Activity:

 1 package com.example.test;
 2 
 3 import android.app.Activity;
 4 import android.content.Context;
 5 import android.content.Intent;
 6 import android.content.IntentFilter;
 7 import android.os.Bundle;
 8 import android.view.Menu;
 9 import android.view.MenuItem;
10 import android.widget.TextView;
11 /**
12  * 实现当插接电源时,手机震动并弹出消息。
13  * @author shaobn
14  * @date 2015-9-19
15  * @packege com.example.testTest
16  */
17 public class MainActivity extends Activity {
18     private TextView text;
19     @Override
20     protected void onCreate(Bundle savedInstanceState) {
21         super.onCreate(savedInstanceState);
22         setContentView(R.layout.activity_main);
23         text = (TextView) this.findViewById(R.id.textView1);
24         IntentFilter intentFilter = new IntentFilter();
25         intentFilter.addAction(Intent.ACTION_POWER_CONNECTED);
26         MyReceiver myReceiver = new MyReceiver();
27         registerReceiver(myReceiver,intentFilter);
28     }
29 }

BroacastReceiver:

 1 package com.example.test;
 2 
 3 import android.content.BroadcastReceiver;
 4 import android.content.Context;
 5 import android.content.Intent;
 6 /**
 7  * 
 8  * @author shaobn
 9  * @date 2015-9-19
10  * @packege com.example.testTest
11  */
12 public class MyReceiver extends BroadcastReceiver {
13 
14     @Override
15     public void onReceive(Context context, Intent arg1) {
16         // TODO Auto-generated method stub
17         Intent intent = new Intent();
18         intent.putExtra("msg","helloworld");
19         intent.setClass(context,MyService.class);
20         context.startService(intent);
21     }
22 }

Service:

 1 package com.example.test;
 2 
 3 import android.app.Service;
 4 import android.content.Intent;
 5 import android.os.IBinder;
 6 import android.os.Vibrator;
 7 import android.widget.Toast;
 8 /**
 9  * 
10  * @author shaobn
11  * @date 2015-9-19
12  * @packege com.example.testTest
13  */
14 public class MyService extends Service {
15 
16     @Override
17     public IBinder onBind(Intent arg0) {
18         // TODO Auto-generated method stub
19         return null;
20     }
21     @Override
22     public void onCreate() {
23         // TODO Auto-generated method stub
24         super.onCreate();
25     }
26     @Override
27     public int onStartCommand(Intent intent, int flags, int startId) {
28         // TODO Auto-generated method stub
29         String message = intent.getStringExtra("msg");
30         Vibrator vibrator = (Vibrator) getSystemService(VIBRATOR_SERVICE);
31         vibrator.vibrate(2000);
32         Toast.makeText(getApplicationContext(),message,1).show();
33         return super.onStartCommand(intent, flags, startId);
34     }
35 }

自己随手写的,程序有点简单,就不写注释了。AndroidManifest.xml中注意配置Service 以及vibrator权限。
