Program Android Vibrator

android.os.Vibrator operates the vibrator on the device.

Your code call getSystemService(AndroidVibratorActivity.VIBRATOR_SERVICE) to retrieve a Vibrator for interacting with the vibration hardware. In the example, touch on button1 to generate vibration for 500ms. Touch and hold on button2 to generate vibration for max 1 second, or release to stop.

You have to modify AndroidManifest.xml to add permission of "android.permission.VIBRATE".

package com.exercise.AndroidVibrator;

import android.app.Activity;
import android.os.Bundle;
import android.os.Vibrator;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.View.OnTouchListener;
import android.widget.Button;

public class AndroidVibratorActivity extends Activity {
 
 Button buttonVibrate1, buttonVibrate2;
 
 Vibrator myVibrator;
 
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        buttonVibrate1 = (Button)findViewById(R.id.buttonVibrate1);
        buttonVibrate2 = (Button)findViewById(R.id.buttonVibrate2);
        
        myVibrator = (Vibrator)getSystemService(AndroidVibratorActivity.VIBRATOR_SERVICE);
        
        buttonVibrate1.setOnClickListener(new OnClickListener(){

   @Override
   public void onClick(View v) {
    // TODO Auto-generated method stub
    myVibrator.vibrate(500);
   }});
        
        buttonVibrate2.setOnTouchListener(new OnTouchListener(){

   @Override
   public boolean onTouch(View v, MotionEvent event) {
    int action = event.getAction();
    
    if(action == MotionEvent.ACTION_DOWN){
     myVibrator.vibrate(1000);
    }else if(action == MotionEvent.ACTION_UP){
     myVibrator.cancel();
    }
    
    return true;
   }});
        
    }
}

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="@string/hello" />

        android:layout_height="wrap_content"
        android:text="Vibrate for 500ms" />
    <Button
        android:id="@+id/buttonVibrate2"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="Touch to Vibrate (max. 1 sec.)" />

</LinearLayout>
