Android实现震动功能

#首先添加权限#

震动开始方法：

 /**
   * @param activity 
   * @param pattern 震动频率
   * @param isRepeat 是否循环执行震动
   */
 public static void starVibrate(final Activity activity, long[] pattern, boolean isRepeat) {
    Vibrator vib = (Vibrator) activity.getSystemService(Service.VIBRATOR_SERVICE);
    vib.vibrate(pattern, isRepeat ? 1 : -1);
  }

震动结束方法：

public static void stopVibrate(final Activity activity) {
    Vibrator vib = (Vibrator) activity.getSystemService(Service.VIBRATOR_SERVICE);
    vib.cancel();
  }
