在我的應用程序中,我已經實現了按下硬件音量鍵顯示當前音量的Toast。大部分時間事情順利。然而長按音量鍵可以成功地使我的應用程序崩潰。上碰撞所產生的日誌如下:Toast崩潰應用程序

我按照該方法: 我有一個烤麪包的對象和用於每個鍵按壓事件檢測的I膨脹的圖,設定內的視圖的元件,將其設置爲烤麪包然後顯示敬酒。
任何想法是什麼問題?

在基本活動類從我的所有活動繼承:
public boolean onKeyDown(int keyCode, KeyEvent event)
{
if(keyCode==KeyEvent.KEYCODE_VOLUME_DOWN)
{
myAudioManager.getInstance().onVolumeDown();
myAudioManager.getInstance().showVolumeAdjustment(myAudioManager.getInstance().getVolume());
return true;
}
else if(keyCode==KeyEvent.KEYCODE_VOLUME_UP)
{
myAudioManager.getInstance().onVolumeUp();
myAudioManager.getInstance().showVolumeAdjustment(myAudioManager.getInstance().getVolume());
return true;
}
return super.onKeyDown(keyCode, event);
}
在myAudioManager
public void showVolumeAdjustment(final int adjustment)
{
volumeToast.setDuration(Toast.LENGTH_SHORT);
volumeToast.setView(getVolumeProgressBarView(adjustment));
volumeToast.setGravity(Gravity.TOP,0,0);
volumeToast.show();
}
private View getVolumeProgressBarView(int adjustment)
{
LayoutInflater inflater = (LayoutInflater) myApplication.getInstance().getApplicationContext()
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
toastView= inflater.inflate(R.layout.volume_toast, null);
ProgressBar pb =(ProgressBar)toastView.findViewById(R.id.level);
pb.setMax(MAX_VOICE_VOLUME_ENGINE);
pb.setProgress(adjustment);
return toastView;
}
您應該發佈顯示您如何設置按鍵事件處理程序的代碼,以及如何顯示敬酒。沒有看到你實際做了什麼,很難說你做錯了什麼。 – Nailuj 2010-11-19 08:20:27
