Ma question est:

Comment ajouter onclicklistener pour le bouton de sélection d'emplacement dans RegisterBlood.Java ou appeler onClickListener qui est dans RegisterBlood.Java à partir de RegisterBloodFragment.Java

Sil te plait aide moi.

Le bouton faisant partie de la présentation du fragment, définissez le programme d'écoute à cet endroit:

@Override
public View onCreateView(LayoutInflater inflater,ViewGroup container, Bundle args) {
    View view = inflater.inflate(R.layout.registerblood, container, false);
    String menu = getArguments().getString("Menu");
    location = (Button) view.findViewById(R.id.etlocation);
    location.setText(menu);
    location.setOnClickListener(this);

    return view;
}

@Override
public void onClick(View v) {
    RegisterBlood activity = (RegisterBlood) getActivity();
    // Now you can contact your activity through activity e.g.:
    activity.onKeyDown(KeyEvent.KEYCODE_MENU, null);
}

Tout d'abord, n'oubliez pas d'implémenter l'interface OnClickListener:

public class YourClassName extends Fragment implements View.OnClickListener

public Button button;

Ensuite, dans la méthode OnCreateView, gonflez le bouton et configurez-le comme suit:

@Override
public View onCreateView(LayoutInflater inflater,ViewGroup container, Bundle args) {

    button = (Button) inflater.inflate(R.layout.registerblood, container, false).findViewById(R.id.your_button_id);
    button.setOnClickListener(this);

}

Puis @Override la fonction onClick et faites ce que vous devez faire:

@Override
public void onClick(View v) {
    //YOUR CODE HERE
}

EDIT Si vous cherchez simplement une FocusListener (dans ce cas, votre question nécessite une mise à jour), définissez le programme d'écoute sur votre méthode onCreateView:

your_edittext.setOnFocusChangeListener(new OnFocusChangeListener() {

@Override
public void onFocusChange(View v, boolean hasFocus) {
    if (hasFocus) {
        Toast.makeText(getApplicationContext(), "got the focus", Toast.LENGTH_LONG).show();
        // OPEN THE DRAWER HERE
    } else {
         Toast.makeText(getApplicationContext(), "lost the focus", Toast.LENGTH_LONG).show();
    }
}

ou vous pouvez implémenter cet auditeur dans votre classe.

vous devez gonfler un fragment comme celui-ci pour cliquer sur un bouton

  View view = inflater.inflate(R.layout.fragment_blank3,
            container, false);
   Button bt1=(Button)view.findViewbyId(R.id.buttton);
   bt1.setOnclick...
   //then return in on create view.
    return view;
