Boîte de dialogue Android et maintien de l'état sur le changement d'orientation de l'écran

Question

I m having trouble with maintaining the dialog on orientation change. I m en utilisant onSaveInstanceState, onRestoreInstanceState. Mais j'ai un null dans onRestore. Je veux que la boîte de dialogue affiche les mêmes valeurs quand je change l'orientation de l'écran. Merci! Voici la boîte de dialogue:

private void ratedialog() { 

     dialog = new Dialog(this); 
     dialog.setContentView(R.layout.dialog); 
     dialog.setTitle("Rate it!"); 
     dialog.setCancelable(true); 
     dialog.show(); 

     seekbar = (SeekBar) dialog.findViewById(R.id.rate_seekbar); 
     button_done = (Button) dialog.findViewById(R.id.button_done); 
     seekbar_result = (TextView) dialog.findViewById(R.id.seekbar_result); 
     checkBox_seen = (CheckBox) dialog.findViewById(R.id.checkBox_seen); 

     button_done.setOnClickListener(EditActivity.this); 
     seekbar.setOnSeekBarChangeListener(EditActivity.this); 
     checkBox_seen.setOnCheckedChangeListener(EditActivity.this); 

     Intent callingIntent = getIntent(); 
     if (callingIntent.getAction().equals(Intent.ACTION_OPEN_DOCUMENT)) { 

      Movie movie = dbHandler.query(id); 
      rate = movie.getRate(); 
      seen = movie.isSeen(); 

      seekbar.setProgress(rate); 
      image_seen.setImageResource(R.drawable.seen); 
      image_seen.setVisibility(View.INVISIBLE); 
      checkBox_seen.setChecked(seen); 
     }else if (callingIntent.getAction().equals(Intent.ACTION_EDIT)){ 
      seekbar.setProgress(rate); 
      image_seen.setImageResource(R.drawable.seen); 
      image_seen.setVisibility(View.INVISIBLE); 
      checkBox_seen.setChecked(seen); 
     }else if (callingIntent.getAction().equals(Intent.ACTION_INSERT)){ 
      seekbar.setProgress(rate); 
      image_seen.setImageResource(R.drawable.seen); 
      image_seen.setVisibility(View.INVISIBLE); 
      checkBox_seen.setChecked(seen); 
     } 


    } 

onSave:

@Override 
    protected void onSaveInstanceState(Bundle outState) { 
     super.onSaveInstanceState(outState); 


     if (rate != 0){ 
      outState.putInt("rate", rate); 
     } 
     outState.putBoolean("check_box", seen); 

onRestrore:

@Override 
    protected void onRestoreInstanceState(Bundle savedInstanceState) { 
     super.onRestoreInstanceState(savedInstanceState); 

     seen = savedInstanceState.getBoolean("check_box"); 
     rate = savedInstanceState.getInt("rate"); 
     checkBox_seen.setChecked(seen); 
     seekbar.setProgress(rate); 

    }
