Boîte de dialogue dans le groupe d'activité à l'intérieur d'un TabActivity ne fonctionne pas

Question

J'essaie d'exécuter un ActivityGroup intégré dans un autre ActivityGroup. (Exemple: un ActivityGroup dans un TabActivity)

Cela semble afficher correctement, mais lancer une exception quand je suis en train pour afficher une boîte modale comme un AlertDialog.

TabActivity 

• Tab1
• Tab2
• MyGroupActivity
• • ChildActivity1
• • ChildActivity2

Si childActivity1 ou 2 essayez d'afficher un DialogBox Je reçois ce exception:

ERROR/AndroidRuntime(2449): 
android.view.WindowManager$BadTokenException: Unable to add window -- 
token android.app.LocalActivityManager$LocalActivityRecord@43424620 is 
not valid; is your activity running? 

Si quelqu'un sait s'il vous plaît répondre ...

Ceci est mon dialogue code de boîte

  final Dialog dialog = new Dialog(EditDeleteReqCardList.this); 
    dialog.setContentView(R.layout.customdialougbox); 
     dialog.setTitle("Request Card - "+reqid); 

     // set the custom dialog components - text, image and button 
     TextView text = (TextView) dialog.findViewById(R.id.text); 
     text.setText("Do You Want to Delete This request Card ?"); 
     ImageView image = (ImageView) dialog.findViewById(R.id.image); 
     image.setImageResource(R.drawable.dialougimage); 

    Button dialogButton = (Button) dialog.findViewById(R.id.dialogButtonOK); 
     Button cancelbutton = (Button) dialog.findViewById(R.id.cancel); 
     dialogButton.setText("Yes"); 
        dialog.show();
