Heartbeat Shock Vibrator Use

Device vibrator, can set the frequency of vibration, simulating the vibration of the heartbeat.

There are two ways to get a device vibrator:

Vibrator = (Vibrator) getsystemservice (Vibrator_service);

Vibrator = (Vibrator) getapplicationcontext (). Getsystemservice (Service.vibrator_service);

There are two ways to turn on the set vibration:

The first type:

vibrator.vibrate (+); Direct Vibration 1000 ms, no waiting time

The second type:

Simulates the frequency of vibrations using an array.

long[] pattern = { ----; {Wait time, vibration time, wait time, vibration time ...}
vibrator.vibrate (Pattern,-1); -1 not repeat, non-1 to start repeating the specified subscript from pattern

First parameter: pattern: Specify the frequency of the vibration, wait 50 milliseconds first, shake 30 milliseconds, wait 60 milliseconds, shake 30 milliseconds ..... has been shaking down this frequency.

The second parameter: <0: Normally set to-1, which means that the frequency is only shaken once, waits 50 milliseconds, and vibrates for 30 milliseconds.

Greater than or equal to 0, but not >=pattern.length, that is, 0<=x<pattern.length, otherwise reported Java.lang.ArrayIndexOutOfBoundsException Exception

Remove Vibration:

Vibrator.cancel ();

Finally, I forgot to add the permissions in the Androidmanifest.xml file:

<uses-permission android:name= "Android.permission.VIBRATE"/>
