Android 振动崩溃

我想为我正在开发的游戏添加振动反馈，以及音乐播放，例如“获胜者”和振动模式。

问题是，当我添加振动句子时，我的应用程序崩溃了。

例如：

 private void Down()
  {
    soundM.playSound(Sound.SOUND_NEWINTENT);

    for (int i=0 ; i<8 ; i++) {
      for (int j=0 ; j<12 ; j++) {
        if (Play[i][j] != null) {
          Play[i][j].moveDown();

          if (Play[i][j].getSpritePosition().y>=380) {
            Sprite.updateState(Sprite.STATE_GAME_LOST);
            endOfGame = true;

            soundM.playSound(Sound.SOUND_LOST);
            vib = (Vibrator)getSystemService(Context.VIBRATOR_SERVICE); 
            vib.vibrate(500); 

          }
        }
      }
    }

它不在活动内部，所以我无法实现像这样的东西 Vibrator v = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE)，因为它是一个活动语句。我尝试声明public Vibrator vib;，然后实现上面显示的代码，但是当游戏失败时，应用程序崩溃了。

我也尝试通过“通知”来完成此操作，但结果相同，应用程序崩溃。

知道如何在其上实现振动吗？

谢谢！！

PS：我有 android.permission.VIBRATE，所以不是问题。事实上，我在菜单上得到了振动。

I want to add a vibration feedback for a game i'm developing, together a music play, like "winner" and a vibrate pattern.

The problem is that when I add the vibrate sentences, my app crashes.

For example:

 private void Down()
  {
    soundM.playSound(Sound.SOUND_NEWINTENT);

    for (int i=0 ; i<8 ; i++) {
      for (int j=0 ; j<12 ; j++) {
        if (Play[i][j] != null) {
          Play[i][j].moveDown();

          if (Play[i][j].getSpritePosition().y>=380) {
            Sprite.updateState(Sprite.STATE_GAME_LOST);
            endOfGame = true;

            soundM.playSound(Sound.SOUND_LOST);
            vib = (Vibrator)getSystemService(Context.VIBRATOR_SERVICE); 
            vib.vibrate(500); 

          }
        }
      }
    }

It is not inside an activity, so I can't implement something like this Vibrator v = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE), because it is an activity statement. I tried to declare public Vibrator vib; and then implement the code I showed above, but when the game lost is recived the application crashes.

I also tried to do it via "notification", but the same result, app crashes.

Any idea how can I implement vibrate on it?

Thanks!!

P.S.: I have android.permission.VIBRATE, so is not the problem. In fact I got virbation working on menu.

我在调用游戏对象的活动中声明一个公共振动器对象。在我的例子中，onCreate 活动启动了一个扩展 SurfaceView 的 MainGamePanel。因此，在 onCreate 活动中，我声明了振动器对象并使用它进行初始化

public static Vibrator v;

v = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);

//Then when I want to game to vibrate, inside of MainGamePanel I call

long[] pattern = { 0, 200, 500 };

DroidzActivity.v.vibrate(pattern, 0);

希望这会有所帮助！

I declare a public vibrator object in the activity that calls the game object. In my case the onCreate activity launches a MainGamePanel that extends a surfaceView. So in the onCreate activity I declare the vibrator object and initialize it with

public static Vibrator v;

v = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);

//Then when I want to game to vibrate, inside of MainGamePanel I call

long[] pattern = { 0, 200, 500 };

DroidzActivity.v.vibrate(pattern, 0);

Hope this helps!
