Activity_main.xml

First, obtain the system vibrator

        Myvibrator = (vibrator) Getsystemservice (service.vibrator_service);         = Mainactivity. this;

Second, judge and set a different frequency of the vibrator

abstract void Cancel (): Close or stop the vibrator

Abstract Boolean Hasvibrator (): Determine if the hardware has a vibrator

void vibrate (long milliseconds): Controls phone vibration of milliseconds milliseconds

void vibrate (long[] pattern,int repeat): Specifies the mode vibration of the phone in pattern specified

First parameter: New int[200,400,600,800], alternately starting and shutting down the vibrator at 200,400,600,800 this time
Second parameter: Repeat number, if 1 is the only vibration once, if it is 0, it has been vibrating

  Public voidOnClick (View v) {Switch(V.getid ()) { CaseR.id.btn_hasvibrator:toast.maketext (Mcontext, Myvibrator.hasvibrator ()? "Current device has vibrators": "Current equipment without vibrators", Toast.length_short). Show ();  Break;  CaseR.id.btn_short:myvibrator.cancel (); Myvibrator.vibrate (New Long[]{100, 200, 100, 200}, 0); Toast.maketext (Mcontext,"Short Vibration", Toast.length_short). Show ();  Break;  CaseR.id.btn_long:myvibrator.cancel (); Myvibrator.vibrate (New Long[]{100, 100, 100, 1000}, 0); Toast.maketext (Mcontext,"Long Vibration", Toast.length_short). Show ();  Break;  CaseR.id.btn_rhythm:myvibrator.cancel (); Myvibrator.vibrate (New Long[]{500, 100, 500, 100, 500, 100}, 0); Toast.maketext (Mcontext,"Rhythm Vibration", Toast.length_short). Show ();  Break;  CaseR.id.btn_cancle:myvibrator.cancel (); Toast.maketext (Mcontext,"Remove Vibration", Toast.length_short). Show (); }    }

Third, open system permissions

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