Android Vibrate on touch?

Question
I am trying to make my device vibrate when I touch an object on Screen. I am using this code:
Vibrator v = (Vibrator) getSystemService(getApplicationContext().VIBRATOR_SERVICE);
v.vibrate(300);
with the permission in the manifest file but I don't seem to get any results. Any suggestions? Also, my hardware supports vibrate.
Solution
please try this :
Button b = (Button) findViewById(R.id.button1);
b.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
// TODO Auto-generated method stub
Vibrator vb = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);
vb.vibrate(100);
return false;
}
});
and add this permission to manifest.xml
<uses-permission android:name="android.permission.VIBRATE"/>
OTHER TIPS
According to this answer, you can perform haptic feedback (vibrate) without asking for any extra permissions. Look at performHapticFeedback
method.
View view = findViewById(...)
view.performHapticFeedback(HapticFeedbackConstants.VIRTUAL_KEY);
Note: I have not tested this code.
This will vibrate once, when user touched view (will not keep vibrating when user still moves his finger!):
@Override
public boolean onTouch(View view, MotionEvent event) {
if(event.getAction() == MotionEvent.ACTION_DOWN) {
Vibrator v = (Vibrator) context.getSystemService(Context.VIBRATOR_SERVICE);
v.vibrate(VIBRATE_DURATION_MS);
}
return true;
}
And as Ramesh said, allow permission in manifest:
<uses-permission android:name="android.permission.VIBRATE"/>
If anyone looking for kotlin
,
val vibrator = context.getSystemService(Context.VIBRATOR_SERVICE) as Vibrator
vibrator.vibrator(durationInMilliSeconds)
and for Android-O and newer,
val vibrationEffect = VibrationEffect.createOneShot(vibrationDuration, vibrationAmplitude)
vibrator.vibrator(vibrationEffect)
while to cancel vibration,
vibrate.cancel()
you also need to add permission in your AndroidManifest.xml
<uses-permission android:name="android.permission.VIBRATE"/>
