Use of Android Vibrator

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 parameter is an array of effects that set the vibration, and the second parameter is 1 for shaking only once, and for 0 the vibrations will persist.

A demo:

Package com.shao.vibrator;

Import android.app.Activity;

Import Android.os.Bundle;

Import Android.os.Vibrator;

Import Android.widget.CompoundButton;

Import Android.widget.Toast;

Import Android.widget.CompoundButton.OnCheckedChangeListener;

Import Android.widget.ToggleButton;

public class Vibratoractivity extends Activity {

Private vibrator Vibrator;

Private ToggleButton Tog1;

Private ToggleButton tog2;

Private ToggleButton Tog3;

@Override

public void OnCreate (Bundle savedinstancestate) {

Super.oncreate (savedinstancestate);

Setcontentview (R.layout.main);

Init ();

Tog1.setoncheckedchangelistener (New Oncheckedchangelistener () {

@Override

public void OnCheckedChanged (Compoundbutton buttonview,

Boolean isChecked) {

TODO auto-generated Method Stub

if (isChecked) {

Set the vibration period

Vibrator.vibrate (New long[] {1000, 10, 100, 1000},-1);

Showtoast ("OK");

} else {

Remove vibrations

Vibrator.cancel ();

Showtoast ("Cancel");

}

}

});

Tog2.setoncheckedchangelistener (New Oncheckedchangelistener () {

@Override

public void OnCheckedChanged (Compoundbutton buttonview,

Boolean isChecked) {

TODO auto-generated Method Stub

if (isChecked) {

Set the vibration period

Vibrator.vibrate (new long[] {100, 100, 100, 1000}, 0);

Showtoast ("OK");

} else {

Remove vibrations

Vibrator.cancel ();

Showtoast ("Cancel");

}

}

});

Tog3.setoncheckedchangelistener (New Oncheckedchangelistener () {

@Override

public void OnCheckedChanged (Compoundbutton buttonview,

Boolean isChecked) {

TODO auto-generated Method Stub

if (isChecked) {

Set the vibration period

Vibrator.vibrate (New long[] {1000, 50, 1000, 50, 1000}, 0);

Showtoast ("OK");

} else {

Remove vibrations

Vibrator.cancel ();

Showtoast ("Cancel");

}

}

});

}

private void init () {

Tog1 = (ToggleButton) Findviewbyid (R.ID.TOG1);

TOG2 = (ToggleButton) Findviewbyid (R.ID.TOG2);

Tog3 = (ToggleButton) Findviewbyid (R.ID.TOG3);

Vibrator = (Vibrator) this.getsystemservice (Vibrator_service);

}

private void Showtoast (String msg) {

Toast.maketext (This, MSG, 1). Show ();

}

}

Finally, don't forget to add <uses-permission android:name= "Android.permission.VIBRATE"/> Permissions.
