Vibrate(Long [] pattern, int repeat): specifies that the mobile phone vibrates in the pattern specified by pattern!
For example, if pattern is new int [200,400,600,800], it is used to enable or disable the vibrator at 200,400,600,800!
The second one is the number of repetitions. If it is-1, it only vibrates once. If it is 0, it always vibrates.
The other two methods are not used much ~

As developers, we all know that the vibrator is responsible for controlling the vibration function of the mobile phone. The Vibrator System in Android is a small system dedicated to this function and provides the time-based Vibration function.
The vibrator system includes the driver,

The vibration in the Android mobile phone is implemented by vibrator. To set a vibration event, you need to know the duration and cycle of the vibration.
In Android, the vibration time is calculated in one millisecond (1/1000 seconds). Therefore, if the set time value is too small, it cannot be felt.
