如何停止Toast.makeText當關閉對話框或退出應用程序

Question

再次。我創建的應用程序通過在Dialog Alert中使用SeekBar來更改TextSize。當我使用seekBarTextSize將更改並顯示字體編號Toast.makeText。但Toast.makeTake不停止增加號碼，顯示消息。當對話關閉和退出應用程序時，它不會停止。我必須在設置或卸載應用程序中強制關閉應用程序。這將停止。我怎樣才能解決這個問題。 再次感謝。

public void ShowDialog() { 
    final AlertDialog.Builder popDialog = new AlertDialog.Builder(this); 
    final SeekBar seek = new SeekBar(this); 

    seek.setMax(100); 

    popDialog.setIcon(R.drawable.conp); 
    popDialog.setTitle(R.string.menu_settings); 
    popDialog.setView(seek); 

    seek.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() { 
     public void onProgressChanged(SeekBar seekBar, int progress, 
       boolean fromUser) { 

      subtitles.setTextSize(progress); 

      Toast.makeText(ShowMan.this, "your textsize :" + String.valueOf(progress), Toast.LENGTH_LONG).show(); 
     } 

     public void onStartTrackingTouch(SeekBar arg0) { 
      // TODO Auto-generated method stub 

     } 

     public void onStopTrackingTouch(SeekBar seekBar) { 
      // TODO Auto-generated method stub 

     } 
    }); 

    // Button 
    popDialog.setPositiveButton("OK", 
      new DialogInterface.OnClickListener() { 
       public void onClick(DialogInterface dialog, int which) { 
        dialog.dismiss(); 
       } 
      }); 

    popDialog.create(); 
    popDialog.show(); 
} 

&我的老師說：「不要用對話框主題。

寫吐司下onStopTrackingTouch（）

public void ShowDialog() { 
final AlertDialog.Builder popDialog = new AlertDialog.Builder(this); 
final SeekBar seek = new SeekBar(this); 
int pgSeekbar; 

seek.setMax(100); 

popDialog.setIcon(R.drawable.conp); 
popDialog.setTitle(R.string.menu_settings); 
popDialog.setView(seek); 

seek.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() { 
    public void onProgressChanged(SeekBar seekBar, int progress, 
      boolean fromUser) { 

     subtitles.setTextSize(progress); 

     pgSeekbar = progress; 
    } 

    public void onStartTrackingTouch(SeekBar arg0) { 
     // TODO Auto-generated method stub 

    } 

    public void onStopTrackingTouch(SeekBar seekBar) { 
     Toast.makeText(ShowMan.this, "your textsize :" + pgSeekbar, Toast.LENGTH_SHORT).show(); 

    } 
}); 

// Button 
popDialog.setPositiveButton("OK", 
     new DialogInterface.OnClickListener() { 
      public void onClick(DialogInterface dialog, int which) { 
       dialog.dismiss(); 
      } 
     }); 

popDialog.create(); 
popDialog.show();
