UserNameYo's questions

I have this problem when compiling my DEBUG app on 4.4, on 8.1 it works perfectly.

I have read many questions about this error but it does not solve the problem, I do not know what to do, my version of Android Studio is 3.5, so it does not have Instant Run

Caused by: java.lang.ClassNotFoundException: Didn't find class "com.google.firebase.provider.FirebaseInitProvider" on path: DexPathList[[zip file "/data/app/com.app-2.apk"],nativeLibraryDirectories =[/data/app-lib/com.app-2, /vendor/lib, /system/lib]]

This is my gradle:

MyApplication

public class MyApplication extends Application {
    @Override
    public void onCreate() {
        super.onCreate();

        MultiDex.install(this);

    }
}

I select an image from the gallery and save the path in Sqliteand so far everything is fine, the problem comes when trying to load the image, it is shown ImageViewempty and on Logcatreceipt twice:

Unable to decode stream: java.io.FileNotFoundException: : open failed: ENOENT (No such file or directory)

Make it clear that ManifestI have the permissions:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

And in the application I have the permissions granted.

The code when I try to load the image:

  private String ruta_imagen = "";

// obtengo todo lo demás correctamente, menos la imagen:

     if (notas != null) {
            ed_titulo.setText(notas.getTitulo());
            ed_nota.setText(notas.getNotas());
            tv_fecha.setText(notas.getFecha());
            tv_persistente.setText(notas.getPersistente());
            tv_categoria.setText(notas.getCategoria());
            image1.setImageBitmap(crearThumb());
        }

  private Bitmap getBitmap(String ruta_imagen) {
        // Objetos.
        File imagenArchivo = new File(ruta_imagen);
        Bitmap bitmap = null;

        if (imagenArchivo.exists()) {
            bitmap = BitmapFactory.decodeFile(imagenArchivo.getAbsolutePath());
        }
        return bitmap;
    }

    private Bitmap crearThumb(){
        Bitmap bitmap = getBitmap(ruta_imagen);
        BitmapFactory.Options opciones = new BitmapFactory.Options();
        opciones.inJustDecodeBounds = true;
        BitmapFactory.decodeFile(ruta_imagen, opciones);

        int scaleW = opciones.outWidth / 854 + 1;
        int scaleH = opciones.outHeight / 480 + 1;
        int scale = Math.max(scaleW, scaleH);

        opciones.inJustDecodeBounds = false;
        opciones.inSampleSize = scale;
        opciones.inSampleSize = scale;
        bitmap = BitmapFactory.decodeFile(ruta_imagen, opciones);
        return bitmap;
    }

I have made this code to try that EditTextEmailyou can only write an email if you write something that is not an email send aToast

    EditText EditTextEmail;
    Button btn1;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        btn1 = (Button) findViewById(R.id.btn1);

        EditTextEmail = (EditText) findViewById(R.id.EditTextEmail);
        final String compruebaemail = EditTextEmail.getEditableText().toString().trim();


        btn1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                if (!compruebaemail.matches("[a-zA-Z0-9._-]+@[a-z]+.[a-z]+"))
                {
                Toast.makeText(MainActivity.this, "Por favor, introduce bien su email", Toast.LENGTH_LONG).show();
                }
            }
        });
    }
}

The problem is basically that I write what I write my commands Toastas if I were writing badly.

Example of text with which it fails:

[email protected]

When I do an account to get the % of a number, I have a problem, let me explain:

I take 5% of 7.74 and it is 0.3870 but I want it to only show me two numbers in the decimal part, that is 0.38 . How can I do this?

And another question I have, is it possible that the result is with a , and not a . ?

This is how I do the process:

public class MainActivity extends AppCompatActivity {

    EditText uno;
    TextView tres;
    Button btn1;

    static final BigDecimal PORCENTAJE_CINCO = new BigDecimal("0.05");

    public BigDecimal calculaCincoPorCiento(BigDecimal numero) {
        return numero.multiply(PORCENTAJE_CINCO);
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        uno = (EditText) findViewById(R.id.uno);
        tres = (TextView) findViewById(R.id.tres);

        btn1 = (Button) findViewById(R.id.btn1);

        btn1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                BigDecimal aux0 = new BigDecimal(uno.getText().toString());
                BigDecimal aux1 = calculaCincoPorCiento(aux0);
                tres.setText(aux1 + " " + "es el 5%");
            }
        });
    }
}

Thank you!

I am trying to do something but I don't know how to do it. Let's see if someone can help me.

I have a EditTextand my intention is that depending on what you write in it, clicking on my Botonwill execute one method and another.

For example, that the correct words are only: " Hello ", " Salut " and Hello ", if you write one of those three words and click on btn1it, the first method is executed. But if you write any other word or none, it is executed the second method.Is this possible?

I leave here what I have been able to do with the code.

public class Main5Activity extends AppCompatActivity {

    EditText text1;
    Button btn1;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main5);

        text1 = (EditText) findViewById(R.id.text1);
        btn1 = (Button) findViewById(R.id.btn1);

        btn1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // si la palabra es correcta:
                Toast.makeText(Main5Activity.this, "Correcto!", Toast.LENGTH_LONG).show();
                // si la palabra no es correcta o no se ha escrito nada:
                Toast.makeText(Main5Activity.this, "No es correcto", Toast.LENGTH_LONG).show();
            }
        });
    }
}

Since I updated Android Studio to 2.3 I'm having problems that don't influence when using the application on my mobile, but if it shows me errors from Android Studio and I don't know if I'll have problems in the future, that's why I want to solve them.

The first is in the gradleand is as follows:

All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 25.1.0, 25.0.2. Examples include com.android.support:animated-vector-drawable:25.1.0 and com.android.support:renderscript:25.0.2

This is my gradle, compile 'com.android.support:appcompat-v7:25.1.0'where I get the above message.

apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.2"
    defaultConfig {
        applicationId "otrointento.dos"
        minSdkVersion 19
        targetSdkVersion 25
        renderscriptTargetApi 19
        renderscriptSupportModeEnabled true
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile files('libs/circleimageview/gradle/wrapper/gradle-wrapper.jar')
    compile 'com.android.support:appcompat-v7:25.1.0'
    compile 'com.github.clans:fab:1.6.2'
    compile 'com.android.support:design:25.1.0'
    compile 'com.google.code.gson:gson:2.3.1'
    compile 'de.hdodenhof:circleimageview:2.1.0'

    compile 'com.android.support.constraint:constraint-layout:1.0.1'
    testCompile 'junit:junit:4.12'
}

Failed to instantiate one or more classes

The following classes could not be instantiated:

I need something like DialogFragmentbut with a full class, in other words create a activityfloat. The procedure is the next:

When I click MainActivityon an Item of my ListViewand it shows me a contextual menu , I select More Information and my class opens MasInformacionloading the data of my Sqliteof that Item , well, with this code I have managed to MasInformacionmake it float (perhaps it is not the best option , if there is a better one you can tell me please) and transparent so that it shows behind my MainActivity, like this:

Well, I want it to be like this:

Not be completely transparent, but have opacity to obscure the 'class' behind it.

MasInformacion: This is how I make it "Floating"

    DisplayMetrics flotante = new DisplayMetrics();
    getWindowManager().getDefaultDisplay().getMetrics(flotante);

    int width = flotante.widthPixels;
    int height = flotante.heightPixels;

    getWindow().setLayout((int)(width*.9),(int)(height*.7));

How can I put the animation like the one WhatsApp has in its search bar when opening and closing:

This is how I have my current animation :

clase

@Override
public void onSearchViewShown() {
    searchView.startAnimation(AnimationUtils.loadAnimation(Cat_sjl.this, R.anim.rotate_image));
}

    @Override
    public void onSearchViewClosed() {       
     searchView.startAnimation(AnimationUtils.loadAnimation(Cat_sjl.this, R.anim.rotate_image));
        adapter.clear();
        adapter.set(titulo.toArray(new String[0]));
    }
});

anim

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <rotate
        android:duration="1500"
        android:fromDegrees="0"
        android:pivotX="50%"
        android:pivotY="50%"
        android:startOffset="0"
        android:toDegrees="360" />
</set>

If I'm not mistaken I should change the animand it will be ready, but which animone do I need?

I have some problems with closing mySearchView

The first: SOLVED

When I search in my listviewand enter the Activityone it finds, when I go back my SearchViewis still open. How can I make it close automatically?

The second: SOLVED

To open my SearchView, I click on the icon (magnifying glass) that I have menu/menu_buscarwith ID action_search. How can I make it so that when it is open and I click it closes?

And finally : SOLVED I have created this code to be able to close my SearchViewfrom the back button of the mobile, but how can I make it so that when it is closed its function is the one that is by default, go back in myActivity

Code to close the SearchViewby clicking on the back button of the mobile

@Override
public void onBackPressed() {
    searchView.closeSearch();
}

Code for the first two questions:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_cat_shishas);
    icon_cat_shi = (ImageView) findViewById(R.id.icon_cat_shi);

    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);

    imagenes = new ArrayList();
    for (Integer pos : new int[]{
            R.drawable.icon_1,
            R.drawable.icon_2,
    }) {
        imagenes.add(pos);
    }
    final ListView lista = (ListView) findViewById(R.id.listview_shi);

    titulo = new ArrayList();
    for (String tit : getResources().getStringArray(R.array.as1)) {
        titulo.add(tit);
    }

    adapter = new IndexAdapter(this, new int[]{0, 1});
    lista.setAdapter(adapter);

    lista.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView adapterView, View view, int posicion, long l) {

            switch ((Integer) adapter.getItem(posicion)) {
                case 0:
                    Intent aln = new Intent(getApplicationContext(), Assq.class);
                    startActivity(aln);
                    break;
                case 1:
                    Intent caer = new Intent(getApplicationContext(), Aassa.class);
                    startActivity(caer);
                    break;
            }
        }
    });

    searchView = (MaterialSearchView) findViewById(R.id.search_view);

    searchView.setOnSearchViewListener(new MaterialSearchView.SearchViewListener() {

        @Override
        public void onSearchViewShown() {

        }

        @Override
        public void onSearchViewClosed() {
            adapter.clear();
            adapter.set(titulo.toArray(new String[0]));
        }
    });

    searchView.setOnQueryTextListener(new MaterialSearchView.OnQueryTextListener() {
        @Override
        public boolean onQueryTextSubmit(String query) {
            return false;
        }

        @Override
        public boolean onQueryTextChange(String newText) {
            if (newText != null && !newText.isEmpty()) {
                List<String> lstFound = new ArrayList();
                for (String item : titulo) {
                    if (item.contains(newText))
                        lstFound.add(item);
                }

                String[] subTitulo = lstFound.toArray(new String[0]);
                adapter.set(subTitulo);
            } else {
                adapter.set(titulo.toArray(new String[0]));
                return true;
            }
            return true;
        }
    });

}


@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.menu_buscar,menu);
    MenuItem item = menu.findItem(R.id.action_search);
    searchView.setMenuItem(item);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch(item.getItemId()) {
        case R.id.action_search:
            icon_cat_shi.setVisibility(View.INVISIBLE);
            return true;
        default:
            return super.onOptionsItemSelected(item);

    }
}

UPDATE:

The first and last question have been solved, I need the second. When I click on action_searchit opens SearchViewup to there everything OK, but I want that when it is open its function is to close it SearchViewhow could I do it?

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.menu_buscar,menu);
    MenuItem item = menu.findItem(R.id.action_search);
    searchView.setMenuItem(item);
    return true;
}

UPDATE 3: to @StefanNolde

I have created a new class calledMyMSView

import com.miguelcatalan.materialsearchview.MaterialSearchView;


public class MyMSView extends MaterialSearchView {

//////////// creo campo MenuItem

    MenuItem mMenuItem;

//////////////// creo el constructor que me pide Android Studio

    public MyMSView(Context context) {
        super(context);
    }

    @Override
    public void setMenuItem(MenuItem menuItem) {
        this.mMenuItem = menuItem;
        mMenuItem.setOnMenuItemClickListener(new MenuItem.OnMenuItemClickListener() {
            @Override
            public boolean onMenuItemClick(MenuItem item) {
                if (isSearchOpen()){
                    closeSearch();
                } else {
                    showSearch();
                }
                return true;
            }
        });
    }
}

So I fill the texts in my listview

 String[] titulo = new String[]{
        "Prueba1",
        "Prueba2",
        "Prueba3",
        "Prueba4",
        "Prueba5",
};

How can I use getString to be able to translate it to any language in string.xml

For example for other texts in my class I use

.setTitle(getResources().getString(R.string.text_1));

How can I do it in this case? Thank you

My code,

ListViewAdapter:

public class ListViewAdapter extends BaseAdapter {
    // Declare Variables
    Context context;
    String[] titulos;
    int[] imagenes;
    LayoutInflater inflater;

    public ListViewAdapter(Context context, String[] titulos, int[] imagenes) {
        this.context = context;
        this.titulos = titulos;
        this.imagenes = imagenes;
    }

    @Override
    public int getCount() {
        return titulos.length;
    }

    @Override
    public Object getItem(int position) {
        return null;
    }

    @Override
    public long getItemId(int position) {
        return 0;
    }

    public View getView(int position, View convertView, ViewGroup parent) {

        // Declare Variables
        TextView txtTitle;
        ImageView imgImg;

        inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        View itemView = inflater.inflate(R.layout.list_row, parent, false);

        // Locate the TextViews in listview_item.xml
        txtTitle = (TextView) itemView.findViewById(R.id.list_row_title);
        imgImg = (ImageView) itemView.findViewById(R.id.list_row_image);

        // Capture position and set to the TextViews
        txtTitle.setText(titulos[position]);
        imgImg.setImageResource(imagenes[position]);

        return itemView;
    }
}

        public int getCount() {

// ------------------------------------------- NUEVO 

 String[] titulos = context.getResources().getStringArray(R.array.titulos); //Obtiene Array.

//----------------------------------------------

            inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

            View itemView = inflater.inflate(R.layout.list_row, parent, false);

            // Locate the TextViews in listview_item.xml
            txtTitle = (TextView) itemView.findViewById(R.id.list_row_title);
            imgImg = (ImageView) itemView.findViewById(R.id.list_row_image);

            // Capture position and set to the TextViews

            imgImg.setImageResource(imagenes[position]);

            return itemView;

    }

String.xml

<string-array name="titulos">
    <item>Uno</item>
    <item>Dos</item>
    <item>Tres</item>
    <item>Cuatro</item>
    <item>Cinco</item>
</string-array>

With these modifications I can already modify the text from the string.xml but I use ListViewAdapter for different classes and when making these modifications in all the classes I get the same texts, those of that array and I need them to be different in each class but using the same ListViewAdapter . Obviously without having to create different ListViewAdapter

UPDATE 2:

string.xml

<resources>
    <string-array name="titulos">
        <item>Uno</item>
        <item>Dos</item>
        <item>Tres</item>
        <item>Cuatro</item>
        <item>Cinco</item>
    </string-array>

    <string-array name="titulos1">
        <item>Seis</item>
        <item>Siete</item>
        <item>Ocho</item>
        <item>Nueve</item>
        <item>Diez</item>
    </string-array>
</resources>

ListViewAdapter:

    public class ListViewAdapter extends BaseAdapter {

        int[] idArray;

public ListViewAdapter(Context context, String[] titulos, int[] imagenes, int[] idArray) {

    this.idArray = idArray;

    String[] titulos = context.getResources().getStringArray(R.array.titulos); //Obtiene Array.

Class:

 int[] idArray = {
 R.array.titulos1,
};

---

adapter = new ListViewAdapter(this, titulo, imagenes, idArray);

How can I change the color of the StatusBar from the java class? For example, to change the color of the navigation bar (the bottom back, home and menu) it would be like this:

getWindow().setNavigationBarColor(getResources().getColor(R.color.colorbar_low));

I would also be interested from color or style but I can't because in AndroidManifest change the Theme AppTheme for Theme.AppCompat.Light to use the App in white and not black colors, and now changing the colorPrimary has no effect.

style:

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>

</resources>

Thank you

My application doesn't work in KK, it stops when I open it, I leave the logcat here:

                Intent work5 = new Intent(descubre_Activity.this, work5Activity.class);
                startActivity(work5);

    }

I have a search bar that should search my listview, but it doesn't, it doesn't search for anything no matter how much I type. I click on the magnifying glass and it opens, I write but it doesn't search for anything.

Example:

Before, I looked for the titles of my ListView, which I obtained from here:

    String[] titulo = new String[]{
        "Android Studio",
        "Java",
        "Xml",
        "Otra Prueba",
};

But my ListViewno longer gets the titles from there, now I have modified my ListViewAdapterso that it gets the titles from array

This is how my code works now:

ListViewAdapter:

public class ListViewAdapter extends BaseAdapter {
    // Declare Variables
    Context context;
    String[] titulos;
    int[] imagenes;
    LayoutInflater inflater;
    int idListaTitulos;

    public ListViewAdapter(Context context, String[] titulos, int[] imagenes, int idListaTitulos) {
        this.context = context;
        this.titulos = titulos;
        this.imagenes = imagenes;
        this.idListaTitulos = idListaTitulos;
    }

    @Override
    public int getCount() {
        return titulos.length;
    }

    @Override
    public Object getItem(int position) {
        return null;
    }

    @Override
    public long getItemId(int position) {
        return 0;
    }

    public View getView(int position, View convertView, ViewGroup parent) {

        // Declare Variables
        TextView txtTitle;
        ImageView imgImg;

        String[] titulos = context.getResources().getStringArray(idListaTitulos);

        inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        View itemView = inflater.inflate(R.layout.list_row, parent, false);

        // Locate the TextViews in listview_item.xml
        txtTitle = (TextView) itemView.findViewById(R.id.list_row_title);
        imgImg = (ImageView) itemView.findViewById(R.id.list_row_image);

        // Capture position and set to the TextViews
        txtTitle.setText(titulos[position]);
        imgImg.setImageResource(imagenes[position]);

        return itemView;
    }
}

And my clase:

public class cocobuzz2 extends AppCompatActivity {
    MaterialSearchView searchView;
    ListViewAdapter adapter;


    String[] titulo = new String[]{
            "Android Studio",
            "Java",
            "Xml",
            "Otra Prueba",
    };

    int[] imagenes = {
            R.drawable.ic_launcher,
            R.drawable.ic_launcher,
            R.drawable.ic_launcher,
            R.drawable.ic_launcher,
    };

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_cocobuzz2);

        final ListView lista = (ListView) findViewById(R.id.listview_coco2);
        adapter = new ListViewAdapter(this, titulo, imagenes, R.array.titulo1);
        lista.setAdapter(adapter);

        lista.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView adapterView, View view, int posicion, long l) {
                switch (posicion) {
                    case 0:
                        Intent a = new Intent(getApplicationContext(), cocobuzz2.class);
                        startActivity(a);
                        break;
                    case 1:
                        Intent b = new Intent(getApplicationContext(), cocobuzz2.class);
                        startActivity(b);
                        break;
                    case 2:
                        Intent c = new Intent(getApplicationContext(), cocobuzz2.class);
                        startActivity(c);
                        break;
                    case 3:
                        Intent d = new Intent(getApplicationContext(), cocobuzz2.class);
                        startActivity(d);
                        break;
                }
            }
        });

        searchView = (MaterialSearchView) findViewById(R.id.search_view);

        searchView.setOnSearchViewListener(new MaterialSearchView.SearchViewListener() {

            @Override
            public void onSearchViewShown() {

            }

            @Override
            public void onSearchViewClosed() {
                //If closed Search View , lstView will return default
                final ListView lista = (ListView) findViewById(R.id.listview_coco2);
                adapter = new ListViewAdapter(cocobuzz2.this, titulo, imagenes, R.array.titulo1);
                lista.setAdapter(adapter);

            }
        });

        searchView.setOnQueryTextListener(new MaterialSearchView.OnQueryTextListener() {
            @Override
            public boolean onQueryTextSubmit(String query) {
                return false;
            }

            @Override
            public boolean onQueryTextChange(String newText) {
                if (newText != null && !newText.isEmpty()) {
                    List<String> lstFound = new ArrayList<String>();
                    for (String item : titulo) {
                        if (item.contains(newText))
                            lstFound.add(item);
                    }

                String[] titulo = lstFound.toArray(new String[0]);

                    adapter = new ListViewAdapter(cocobuzz2.this, titulo, imagenes, R.array.titulo1);
                    lista.setAdapter(adapter);
                } else {
                    //if search text is null
                    //return default
                    adapter = new ListViewAdapter(cocobuzz2.this, titulo, imagenes);
                    lista.setAdapter(adapter);
                }
                return true;
            }

        });
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.menu_item,menu);
        MenuItem item = menu.findItem(R.id.action_search);
        searchView.setMenuItem(item);
        return true;
    }
}

And now having added that it obtain the titles of array (values-string) -titles1- and my search engine does not search for anything, so I imagine that my error is here:

        @Override
        public boolean onQueryTextChange(String newText) {
            if (newText != null && !newText.isEmpty()) {
                List<String> lstFound = new ArrayList<String>();
                for (String item : titulo) {
                    if (item.contains(newText))
                        lstFound.add(item);
                }

// Al añadir esta linea ya me buscaba, PERO, cuando cambie la forma de obtener los títulos, dejó de hacerlo.

                    String[] titulo = lstFound.toArray(new String[0]);

// ---

                adapter = new ListViewAdapter(cocobuzz2.this, titulo, imagenes, R.array.titulo1);

My String with its array

    <resources>

...
        <string-array name="titulos1">
            <item>Android Studio</item>
            <item>Java</item>

How can I calculate the age (including day and month) using an EditText? Right now I do it through a Calendar, but I would like that when writing the date 01/23/2017 (Example) in the EditText the age is calculated.

EditText that I want to use to calculate the age:

editText1=(EditText) findViewById(R.id.editText1);

MainActivity:

public class MainActivity extends Activity implements OnClickListener{
    private Button btnStart;
    static final int DATE_START_DIALOG_ID = 0;
    private int startYear=1970;
    private int startMonth=6;
    private int startDay=15;
    private AgeCalculation age = null;
    private TextView currentDate;
    private TextView birthDate;
    private TextView result;

    EditText editText1;
    TextView edad;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        age=new AgeCalculation();
        currentDate=(TextView) findViewById(R.id.textView1);
        currentDate.setText("Current Date(DD/MM/YY) : "+age.getCurrentDate());
        birthDate=(TextView) findViewById(R.id.textView2);
        result=(TextView) findViewById(R.id.textView3);
        edad=(TextView) findViewById(R.id.edad);
        editText1=(EditText) findViewById(R.id.editText1);
        btnStart=(Button) findViewById(R.id.button1);
        btnStart.setOnClickListener(this);

    }

    @Override
    protected Dialog onCreateDialog(int id) {
        switch (id) {
            case DATE_START_DIALOG_ID:

When I put this link:

http://www.writeurl.com/text/hc2m5gy29z0byqvo53ug/38nftxs4azvgifrbq6m9

Which is a website that allows you to update the online text in my application without having to edit the App.

But it always gives me an error: "We are trying to connect to the server." If I use, for example, Google if it works and other websites but not that one in particular, why is that? I'm also interested in another option for what I want to do.

My code:

public class MainActivity extends AppCompatActivity {

    private WebView view;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        view = (WebView) this.findViewById(R.id.prueba);
        view.getSettings().setJavaScriptEnabled(true);
        view.setWebViewClient(new MyBrowser());
        view.loadUrl("http://www.writeurl.com/text/hc2m5gy29z0byqvo53ug/38nftxs4azvgifrbq6m9"); 
        view.setWebChromeClient(new WebChromeClient()); 
    }

    private class MyBrowser extends WebViewClient {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            view.loadUrl(url);
            return true;
        }
    }

    public boolean onKeyDown(int keyCode, KeyEvent event) {
        if ((keyCode == KeyEvent.KEYCODE_BACK) && view.canGoBack()) {
            view.goBack();
            return true;
        }
        return super.onKeyDown(keyCode, event);
    }

}

What should I do so that when my application sends a second (third... fourth... etc) notification it is not replaced and all are included?

MainActivity.java:

public class MainActivity extends ActionBarActivity {

    DatePicker datePicker;
    TimePicker timePicker;
    Button btnStart;

        setContentView(R.layout.notif_main);

        datePicker = (DatePicker)findViewById(R.id.datepicker);
        timePicker = (TimePicker)findViewById(R.id.timepicker);

        textonombre = (EditText)findViewById(R.id.textonombre);
        textodescripcion = (EditText)findViewById(R.id.textodescripcion);

                }
        });
    }

                datePicker.getMonth(),
                datePicker.getDayOfMonth(),

        alarmManager.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), pendingIntent);

    }
}

AlarmReceiver.java

public class AlarmReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {

        NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);

        Intent repeating_intent = new Intent(context,MainActivity.class);
        repeating_intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);


        PendingIntent pendingIntent = PendingIntent.getActivity(context,id,repeating_intent, PendingIntent.FLAG_UPDATE_CURRENT);


        NotificationCompat.Builder builder = (NotificationCompat.Builder) new NotificationCompat.Builder(context)
                .setContentIntent(pendingIntent)
                .setSmallIcon(R.drawable.ic_launcher)
                .setContentTitle("NOMBRE")
                .setContentText("DESCRIPCIÓN")
                .setAutoCancel(true);
        notificationManager.notify(id,builder.build());

    }
}

Edit: @Elenasys

public class AlarmReceiver extends BroadcastReceiver {

    int id= 1;

    @Override
    public void onReceive(Context context, Intent intent) {



        NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);

        Intent repeating_intent = new Intent(context,MainActivity.class);
        repeating_intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

        NotificationCompat.Builder builder = (NotificationCompat.Builder) new NotificationCompat.Builder(context)
                .setContentIntent(pendingIntent)
                .setSmallIcon(R.drawable.ic_launcher)

Why doesn't it create the .png I'm trying to get it to create from the selected image?

I don't get any errors, it just doesn't get created, why is that?

The problem is that when I click on the floating button it does the action, but when I return to the main Activity, the floating menu is still open, why doesn't it close? I leave a GIF so you can see the problem better:

Code:

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        btn_flo_menu = (FloatingActionMenu) findViewById(R.id.icon_btn_flo_menu);
        btn_flo_1 = (FloatingActionButton) findViewById(R.id.icon_btn_flo_1);
        btn_flo_2 = (FloatingActionButton) findViewById(R.id.icon_btn_flo_2);
        btn_flo_3 = (FloatingActionButton) findViewById(R.id.icon_btn_flo_3);


        btn_flo_1.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                editarPersona(0);
            }
        });


        btn_flo_2.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {


            }
        });
        btn_flo_3.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {


            }
        });

I click on the image and it lets me select one from the gallery, but when I select it it doesn't change. I know I'm missing a part of the code, could someone help me with it? Thank you!
