Problems closing SearchView

  • 772

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;
            }
        });
    }
}

  1. Best Answer

    para caso 1

    para cerrar el searchView antes de partir a otras actividades:

    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);
                if (searchView.isSearchOpen()) searchView,closeSearch();
                startActivity(aln);
                break;
            case 1:
                Intent caer = new Intent(getApplicationContext(), Aassa.class);
                if (searchView.isSearchOpen()) searchView,closeSearch();
                startActivity(caer);
                break;
        }
    }
});

    para caso 2

    en onOptionsItemSelectedpuedes diferenciar:

    if (null!=searchView && searchView.isSearchOpen()){
    searchView.close();
    return true;
} else {
    // cosas que hacer para la busqueda
    return true;
}

    Pero como el searchView te tapa el menu, tienes que modificar el listener en MaterialSearchView. Revisando el código fuente de MaterialSearchView, lo siguiente te debería solucionar lo que quieres hacer:

    // vamos a hacer una subclase de MaterialSearchView:
public class MyMSView extends MaterialSearchView{

    public MyMSView(Context context) {
        this(context, null);
    }

    public MyMSView(Context context, AttributeSet attrs) {
        this(context, attrs, 0);
    }

    public MyMSView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs);

    }

    @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;
            }
        });
    }
}

    luego usas MyMSView en ves de MaterialSearchView en tu actividad.

    para caso 3 cerrar en onBackPressed()

    si te entiendo bien, quieres mantener la función original de onBackPressed(). Si quieres eso, no deberías olvidar en un @Override de tambien llamar la función original:

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

    o si quieres hacer la una o la otra cosa, dependiente si el searchView esta abierto:

    @Override
public void onBackPressed() {
    if (searchView.isSearchOpen()) {
        searchView.closeSearch();
    } else {
        super.onBackPressed();
    }
}

    actualisación

    Tu delincuente se encuentra aquí:

    Caused by: java.lang.ClassCastException: com.miguelcatalan.materialsearchview.MaterialSearchView cannot be cast to otrointento.dos.categorias.Cat_prueba$MyMSView
   at otrointento.dos.categorias.Cat_prueba.onCreate(Cat_prueba.java:188)

    tu tienes que cambiar los casts:

    searchView = (MaterialSearchView)

    tiene que ser 

    searchView = findViewById(R.id.search_view);

    y searchView tiene que ser declarado como MyMSView. Una parte donde no tienes que cambiar al nombre de la nueva clase es:

    new MyMSView.OnQueryTextListener()

    eso NO funciona, tienes que seguir declarando MaterialSearchView.OnClickListener(), porque la clase interna sigue siendo lo mismo. Cuando uno hace una subclase, no se lleva todos los aspectos estáticos. En general mientras corriges los errores, recuerda:

    • La instancia (new Class()...) tiene que ser tu nueva clase.
    • La variable deberías declarar como tu nueva clase
    • el layout debe tener el <tag> de tu nueva clase
    • en el contexto estático sigues usando MaterialSearchView, por ejemplo en nombres de clases internos

    actualisación 2

    import com.miguelcatalan.materialsearchview.MaterialSearchView;
// aquí tienes que importar tu clase (si no es en el mismo paquete)

public class Cat_shishas extends AppCompatActivity {

    ///////////////// cambio MaterialSearchView searchView; por:

                        break;

                        if (item.contains(newText))
                            lstFound.add(item);
                    }

                    // usemos otro nombre de variable para mas claridad
                    // aun que diferenciemos entre this.titulo y titulo, así queda mas obvio
                    String[] subTitulo = lstFound.toArray(new String[0]);
                    // de nuevo, quedemos con el mismo adapter.
                    adapter.set(subTitulo);
                } else {
                    //if search text is null
                    //return default
                    // y de nuevo ;)
                    adapter.set(titulo.toArray(new String[0]));
                    return true;
                }
                return true;
            }

        });

    }

    @Override
    public void onBackPressed() {
        if (searchView.isSearchOpen()) {
            searchView.closeSearch();
        } else {
            super.onBackPressed();
        }
    }


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

    Me da la impresión que haces mucho "monkey patching", usando código de ejemplos que en el fondo no entiendes bien. Te recomiendo de meterte un poco en los básicos, Java basico, conceptos de POO. Mira aqui:

    ¡No temas a la POO!

    tu problema es eso:

            <com.miguelcatalan.materialsearchview.MaterialSearchView
            android:id="@+id/search_view"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            app:searchBackground="@drawable/contorno_design"
            app:searchSuggestionBackground="@color/colorPrimary"
            app:searchCloseIcon="@drawable/ic_action_navigation_close_inverted"
            app:searchBackIcon="@drawable/ic_action_navigation_arrow_back_inverted"
            app:searchSuggestionIcon="@drawable/ic_suggestion"
            android:textColor="#FFFFFF"
            android:textColorHint="#FFFFFF"
            android:layout_marginEnd="70dp"
            android:layout_marginStart="70dp"
            android:layout_marginTop="10dp"
            android:elevation="2dp" />

    tiene que ser:

            <otrointento.dos.MyMSView
            android:id="@+id/search_view"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            app:searchBackground="@drawable/contorno_design"
            app:searchSuggestionBackground="@color/colorPrimary"
            app:searchCloseIcon="@drawable/ic_action_navigation_close_inverted"
            app:searchBackIcon="@drawable/ic_action_navigation_arrow_back_inverted"
            app:searchSuggestionIcon="@drawable/ic_suggestion"
            android:textColor="#FFFFFF"
            android:textColorHint="#FFFFFF"
            android:layout_marginEnd="70dp"
            android:layout_marginStart="70dp"
            android:layout_marginTop="10dp"
            android:elevation="2dp" />

    Faltaban los constructores en MyMSView. lo he actualizado arriba.

  2. 1) Actually what you are opening is the menu and not the SearchView, to detect if the SearchView is opening you can add a Listener, you get the ImageView reference and change its visibility:

    SearchView searchView = (SearchView) findViewById(R.id.searchView);
    searchView.setOnSearchClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            icon_cat_shi.setVisibility(View.INVISIBLE);

        }
    });

    2) para cerrarlo programaticamente en otra acción además de activar el botón "regreso" puedes implementar que cuando es abre otra Activity se cierre mediante:

     if (!searchView.isIconified()) {
        searchView.onActionViewCollapsed();
 }
