android振动器(Vibrator)

Vibrator三个常用的方法

  void android.os.Vibrator.vibrate(long milliseconds)震动milliseconds秒钟

  void android.os.Vibrator.cancel()关闭手机震动

  void android.os.Vibrator.vibrate(long[] pattern, int repeat)指定手机以pattern指定的震动模式；比如vibrate(new int[]{400,800,1200,1600},2)表示在数组索引为2这个时间点开始循环来震动；这些循环的震动的时间点就是数组的数值，震动在这些时间点交替启动、关闭振动器。
