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 ~

Mobile phones have the effect of vibration. The day before yesterday, the flying knife removed a vibrator from the mobile phone, and asked me to tune it next week. Yesterday, I came to the company for a test and got it done. Let's talk about the process below.
In fact, the underlying driver has been completed in Android, that is, timed_gpio, which combines the timing function with the gpio

The vibrations in Android phones are implemented by vibrator. To set a vibration event, you need to know the length of the vibration, the period of vibration and so on.In Android vibrator, the vibration time is calculated in milliseconds (1/1000 seconds), so if the set time value is too small, it will not feel.Implemented by calling Vibrator's vibrate (long[] pattern, int repeat) method.The previous paramet
