setContentView pour alertDialog

faire votre propre boîte de dialogue

class YourDialog extends Dialog {

private TextView mTextView1, mTextView1;
private Button mButton1, mButton2;

public YourDialog(Context context) {
    super(context);


}

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

    //init your component from layout
    //and add listiner to them

}

}

J'avais été confronté exactement au même problème.

Voici ce que j'ai fait après une recherche.

activity_main.xml

MainActivity.java

public class MainActivity extends AppCompatActivity implements myDialogFragment.MyDialogListener {
private Button buttonAdd;
private myDialogFragment dialog;

@Override

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

    dialog = new myDialogFragment();
    buttonAdd = (Button)findViewById(R.id.button_add_title);

    buttonAdd.setOnClickListener(new View.OnClickListener() {

        public void onClick(View v) {
            Log.i("MainActivity", "onClick: going to show dialog");
            dialog.show(getSupportFragmentManager(), "myCustomAlert !!");

        }
    });

}

@Override
public void onDialogPositiveClick(DialogFragment dialog, String name, String desc) {
    Toast.makeText(getApplicationContext(), "name :" + name + "description :" + desc, Toast.LENGTH_SHORT).show();
}

@Override
public void onDialogNegativeClick(DialogFragment  dialog) {
    Toast.makeText(getApplicationContext(), "Cancel clicked", Toast.LENGTH_SHORT).show();
    }
}

myDialogFragment.java

Lors de l'utilisation de la bibliothèque de prise en charge, assurez-vous que vous importez android.de soutien.v4.app.DialogFragment classe et pas android.app.DialogFragment.
