I am making a date picker and when I select the date it starts at 1900, however the time starts at the current time. Is there a way to make the date to choose start at the current date?

Code:

public class MainActivity extends AppCompatActivity implements View.OnClickListener {

int longitudvector=0;
Context context;
// IP de mi Url
String IP = "http://alquilalo.esy.es";
// Rutas de los Web Services
String GET = IP + "/obtener_vehiculos.php";



String semail;

//String recogerdia;
String rdia,rmes,rano,rhora,rminutos;
String ddia,dmes,dano,dhora,dminutos;

//String recogerdiaentero;
Button bfecha,bhora;
EditText efecha,ehora;
public  int dia,mes,ano,hora,minutos;

Button b2fecha,b2hora;
EditText e2fecha,e2hora;
public  int dia2,mes2,ano2,hora2,minutos2;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    context=this;


    //Toast.makeText(this, semail, Toast.LENGTH_SHORT).show();

    bfecha=(Button)findViewById(R.id.bfecha);
    bhora=(Button)findViewById(R.id.bhora);
    efecha=(EditText)findViewById(R.id.efecha);
    ehora=(EditText)findViewById(R.id.ehora);

    b2fecha=(Button)findViewById(R.id.b2fecha);
    b2hora=(Button)findViewById(R.id.b2hora);
    e2fecha=(EditText)findViewById(R.id.e2fecha);
    e2hora=(EditText)findViewById(R.id.e2hora);

    bfecha.setOnClickListener(this);
    bhora.setOnClickListener(this);

    b2fecha.setOnClickListener(this);
    b2hora.setOnClickListener(this);



}

@Override

I have this ListviewAdapter and I would like to know how I can add a similar button for each element of the list, that when pressed it directs me to another activity.

public class ListViewAdapter extends BaseAdapter {
// Declare Variables
Context context;
String[] titulos;
Bitmap[] imagenes;
LayoutInflater inflater;
String[] plazas;
String[] puertas;
String[] maletas;
String[] aire;
String[] transmision;

public ListViewAdapter(Context context, String[] titulos, Bitmap[] imagenes, String[] plazas,String[] puertas,String[] maletas,String[] aire,String[] transmision) {
    this.context = context;
    this.titulos = titulos;
    this.imagenes = imagenes;
    this.plazas=plazas;
    this.puertas=puertas;
    this.maletas=maletas;
    this.aire=aire;
    this.transmision=transmision;

}

@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;
    TextView txplazas;
    TextView txpuertas;
    TextView txmaletas;
    TextView txaire;
    TextView txtransmision;
    //http://developer.android.com/intl/es/reference/android/view/LayoutInflater.html
    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);

    txplazas = (TextView) itemView.findViewById(R.id.tplazas);
    txpuertas = (TextView) itemView.findViewById(R.id.tpuertas);
    txmaletas = (TextView) itemView.findViewById(R.id.tmaletas);
    txaire = (TextView) itemView.findViewById(R.id.taire);
    txtransmision = (TextView) itemView.findViewById(R.id.ttransmision);

    // Capture position and set to the TextViews
    txtTitle.setText(titulos[position]);
    imgImg.setImageBitmap(imagenes[position]);
    txplazas.setText(plazas[position]);
    txpuertas.setText(puertas[position]);
    txmaletas.setText(maletas[position]);
    txaire.setText(aire[position]);

    return itemView;
}
}



public class MainActivity extends AppCompatActivity {

@Override

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);


    String[] titulo = new String[]{
            "titulo1",
            "titulo2",
            "titulo3",
            "titulo4",
    };

    Bitmap[] imagenes = {
            BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher),
            BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher),

    adapter = new ListViewAdapter(this, titulo, imagenes,plazas,puertas,maletas,aire,transmision);
    lista.setAdapter(adapter);

}
}

I have read in other similar questions in the forum but I have not been able to solve it. I suspect that I have to put these instructions, but I do not know where and if it is really like that:

Button boton;
boton = (Button) itemView.findViewById(R.id.botonact1);

lista.setOnItemClickListener(
            new AdapterView.OnItemClickListener() {
                @Override
                public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

                    // Abre una nueva Activity:
                    Intent myIntent = new Intent(view.getContext(), Pago.class);
                    startActivity(myIntent);

                }
            }
    );

These are the errors that the logcat shows me

I have found a code for a listview with images on this page: http://cursoandroidstudio.blogspot.com.es/2014/07/listview-con-imagenes.html I need it to work with bitmap type, I have changed everything of the type int[] to Bitmap[] . The result is as follows:

public class MainActivity extends AppCompatActivity {

ListViewAdapter adapter;

String[] titulo = new String[]{
        "titulo1",
        "titulo2",
        "titulo3",
        "titulo4",
};

Bitmap[] imagenes = {
        BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher),
        BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher),
        BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher),
        BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher)
};

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

    final ListView lista = (ListView) findViewById(R.id.listView1);
    adapter = new ListViewAdapter(this, titulo, imagenes);
    lista.setAdapter(adapter);

    }
}



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

public ListViewAdapter(Context context, String[] titulos, Bitmap[] 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;

    //http://developer.android.com/intl/es/reference/android/view/LayoutInflater.html
    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.setImageBitmap(imagenes[position]);

        return itemView;
    }
}

But it doesn't work for me, does anyone know why or how I can fix it?
