Android Erreur: impossible d'ajouter une fenêtre - le token null n'est pas pour une application

Hy. J'ai essayé de créer une boîte de dialogue d'alerte mais lorsque j'exécute mon application, je lance une exception

Voici mon code:

public class DeleteRewardsFragment extends Fragment{

private Context context;

private FragmentsActivity activity;

private ListView listView;
private View myFragmentView;
private DeleteRewardsAdapter adapter;
private String[] values;

@SuppressLint("ResourceAsColor")
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

    myFragmentView = inflater.inflate(R.layout.listview, container, false);
    listView = (ListView) myFragmentView.findViewById(Android.R.id.list);


    activity = (FragmentsActivity) getActivity();
    context = activity.getApplicationContext();

    values = new String[4];

    adapter = new DeleteRewardsAdapter(context, values);
    listView.setAdapter(adapter);
    listView.setOnItemClickListener(deleteEvent);

    return myFragmentView;

}

private OnItemClickListener deleteEvent = new OnItemClickListener() {

    @Override
    public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
            long arg3) {
        AlertDialog.Builder alertDialog  = new AlertDialog.Builder(context);
        alertDialog .setTitle("Jetzt löschen?");
        alertDialog .setMessage("Die in deisem Store gesammelten stampss gehen debei verloren!")
                .setCancelable(false)
                .setPositiveButton("Abbrechen", new DialogInterface.OnClickListener() {

                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        values = new String[values.length-1];
                        adapter = new DeleteRewardsAdapter(context, values);
                        listView.setAdapter(adapter);
                    }
                })
                .setNegativeButton("Löschen", new DialogInterface.OnClickListener() {

                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        dialog.cancel();
                    }
                });

        AlertDialog dialog = alertDialog.create();
        dialog.show();

    }
};

}

Quelqu'un peut-il m'aider?

Pour ajouter AlertDialog à votre Activity ou Fragment vous devez utiliser l'instance de votre Activity, pas celle de votre application que vous faites dans votre code. Créez votre AlertDialog comme ceci:

AlertDialog.Builder alertDialog  = new AlertDialog.Builder(getActivity());

Et cela devrait faire l'affaire pour vous! :)

Dans mon cas, j'essayais de créer ma boîte de dialogue comme ceci:

new Dialog(getApplicationContext());

J'ai donc dû changer pour:

new Dialog(MyActivity.this);

Et ça a commencé à fonctionner.

Vous trouverez ci-dessous ce que vous pouvez faire pour résoudre le problème.

  1. À la place d'utiliser

      context
    Tu devrais utiliser
      ActivityName.this

  2. si vous utilisez getApplicationContext (), utilisez l'indicateur ci-dessous avant d'utiliser getApplicationContext ()

      dialog.getWindow().setType(WindowManager.LayoutParams.TYPE_SYSTEM_ALERT)  

Ajoutez l'autorisation suivante à votre manifeste:

<uses-permission Android:name="Android.permission.SYSTEM_ALERT_WINDOW" />

Envoyez l'activité plutôt que le contexte.

AlertDialog.Builder alertDialog  = new AlertDialog.Builder(activity);

J'ai changé:

ProgressDialog(getApplicationContext());

à:

ProgressDialog(MainActivity.this);

J'ai changé getApplicationContext() en

activity.this

ça va marcher
