device vibration keeps repeating infinitely

im trying to vibrate device and repeat this pattern for 3 times so in total 6x vibrations. Im using code bellow but my device keeps vibrating infinitely. How to stop vibrating after those 3 repeats?

private void deviceVibration (){
   
   long[] pattern = {0, 2000, 1000, 2000,1000};
   vibrator.vibrate(pattern,3);

}
Solution

  • According to the Vibrator Documentation

    public void vibrate (long[] pattern, int repeat)

    This long[] pattern is an array of longs of times for which to turn the vibrator on or off. This int repeat is the index into pattern at which to repeat, or -1 if you don't want to repeat.

    So if you put the 3 it will repeat the 3 index position of your pattern.

    long[] pattern = {0, 2000, 1000, 2000,1000}; <-- 2000 will be repeated

    So the pattern is ok, you need to remove one to just vibrate three times and then just change your 3 for -1 to don't repeat.
