Erreur de dépassement de pile Stack android?

Question

Mon code fonctionnait bien, mais soudainement, lorsque j'ai réexécuté le code, cela m'a donné une erreur de débordement de pile. Voici mon code: HelloDatePickerActivity a déjà été défini.

HelloDatePickerActivity daten=new HelloDatePickerActivity(); 
     static final int DATE_DIALOG_ID = 0;  
     Button mPickDate; 
     TextView mDateDisplay; 

     /** Called when the activity is first created. */ 
     @Override 
     public void onCreate(Bundle savedInstanceState) { 

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

    mPickDate=(Button)findViewById(R.id.pickDate); 

     mPickDate.setOnClickListener(new View.OnClickListener() { 
      public void onClick(View v) { 
       showDialog(DATE_DIALOG_ID); 
      } 
     });   
    } 
     @Override 
     protected Dialog onCreateDialog(int id) { 
      switch (id) { 
      case DATE_DIALOG_ID: 
       return new DatePickerDialog(this, 
          daten.mDateSetListener, 
          daten.mYear, daten.mMonth, daten.mDay); 
      } 
      return null; 
     }   

} 

Et le Logcat est:

Answer 1

HelloDatePickerActivity daten=new HelloDatePickerActivity(); 

Voici votre problème. Penses-y.

Editer: Quoi qu'il en soit, vous devez comprendre qu'appeler new Activity() est une mauvaise pratique de programmation. Malheureusement, je ne peux pas fournir de référence de documentation en disant exactement cela. Some relatively useful reference about creating new activities.
