Question

在我的应用程序中，我实现了按下硬件音量键，显示当前音量的Toast。事情大部分时间都很顺利。但是，长按音量键确实会导致我的应用程序崩溃。崩溃时生成的日志如下：

....

...many such notifications...

11-19 06:43:22.244 W/WindowManager( 2783): Due to memory failure, waiting a bit for next layout

我遵循的方法：我有一个toast对象，并且对于检测到的每个按键事件，我都会给视图充气，设置视图元素，将其设置为toast然后显示toast。

知道出了什么问题吗？

在我的所有活动继承的基本活动类中：

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中

 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;
 }

你制作了太多的祝酒词，并填满了记忆。

尝试使用计时器或其他东西来限制生成的吐司数量。
