Android - OnCreateDialog se bloque lors du retour DatePickerDialog

Question

Je suis actuellement en train d'élever un DatePickerDialog chaque fois qu'un certain EditText est cliqué. Cependant, chaque fois que je clique sur EditText, l'application se bloque. Voici le code pertinent et LogCat.

Le EditText et son OnClickListener:

addBirth.setClickable(true); 
    addBirth.setOnClickListener(new OnClickListener() { 

     @Override 
     public void onClick(View v) { 
      // TODO Auto-generated method stub 
      showDialog(DATE_DIALOG_ID); 
     } 
    }); 

La méthode onCreateDialog et DateSetListener:

@Override 
protected Dialog onCreateDialog(int id) { 
    // TODO Auto-generated method stub 
    switch (id) { 
    case DATE_DIALOG_ID: 
     DatePickerDialog dialog = new DatePickerDialog(getApplicationContext(), mDateSetListener, mYear, mMonth, mDay); 
     return dialog; 
    } 
    return null; 
} 

protected DatePickerDialog.OnDateSetListener mDateSetListener = 
     new DatePickerDialog.OnDateSetListener() { 

      @Override 
      public void onDateSet(DatePicker view, int year, int monthOfYear, 
        int dayOfMonth) { 
       mYear = year; 
       mMonth = monthOfYear; 
       mDay = dayOfMonth; 
       updateDisplay(); 

      } 
     }; 
private void updateDisplay() { 
    addBirth.setText(
      new StringBuilder() 
        .append(mMonth + 1).append("-") 
        .append(mDay).append("-") 
        .append(mYear).append(" ")); 
} 

Et voici le LogCat:

Answer 1

Ne jamais utiliser getApplicationContext() pour créer des boîtes de dialogue.

Essayez ceci.

DatePickerDialog dialog = new DatePickerDialog(YourActivity.this, mDateSetListener, mYear, mMonth, mDay);
