Android 利用Service BroadcastReceiver实现小例子

Activity：

 package com.example.test;

 import android.app.Activity;
 import android.content.Context;
 import android.content.Intent;
 import android.content.IntentFilter;
 import android.os.Bundle;
 import android.view.Menu;
 import android.view.MenuItem;
 import android.widget.TextView;
 /**
  * 实现当插接电源时，手机震动并弹出消息。
  * @author shaobn
  * @date 2015-9-19
  * @packege com.example.testTest
  */
 public class MainActivity extends Activity {
     private TextView text;
     @Override
     protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.activity_main);
         text = (TextView) this.findViewById(R.id.textView1);
         IntentFilter intentFilter = new IntentFilter();
         intentFilter.addAction(Intent.ACTION_POWER_CONNECTED);
         MyReceiver myReceiver = new MyReceiver();
         registerReceiver(myReceiver,intentFilter);
     }
 }

BroacastReceiver:

 package com.example.test;

 import android.content.BroadcastReceiver;
 import android.content.Context;
 import android.content.Intent;
 /**
  *
  * @author shaobn
  * @date 2015-9-19
  * @packege com.example.testTest
  */
 public class MyReceiver extends BroadcastReceiver {

     @Override
     public void onReceive(Context context, Intent arg1) {
         // TODO Auto-generated method stub
         Intent intent = new Intent();
         intent.putExtra("msg","helloworld");
         intent.setClass(context,MyService.class);
         context.startService(intent);
     }
 }

Service:

 package com.example.test;

 import android.app.Service;
 import android.content.Intent;
 import android.os.IBinder;
 import android.os.Vibrator;
 import android.widget.Toast;
 /**
  *
  * @author shaobn
  * @date 2015-9-19
  * @packege com.example.testTest
  */
 public class MyService extends Service {

     @Override
     public IBinder onBind(Intent arg0) {
         // TODO Auto-generated method stub
         return null;
     }
     @Override
     public void onCreate() {
         // TODO Auto-generated method stub
         super.onCreate();
     }
     @Override
     public int onStartCommand(Intent intent, int flags, int startId) {
         // TODO Auto-generated method stub
         String message = intent.getStringExtra("msg");
         Vibrator vibrator = (Vibrator) getSystemService(VIBRATOR_SERVICE);
         vibrator.vibrate(2000);
         Toast.makeText(getApplicationContext(),message,1).show();
         return super.onStartCommand(intent, flags, startId);
     }
 }

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。
