在Service中使用广播接受者

1、清单文件

 <service android:name="com.example.callmethod.MyService"></service>

2、开启服务和发送广播

 package com.example.callmethod;

 import android.os.Bundle;
 import android.app.Activity;
 import android.content.Intent;
 import android.view.Menu;
 import android.view.View;

 public class MainActivity extends Activity {

     @Override
     protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.activity_main);
         Intent intent = new Intent(this, MyService.class);
         startService(intent);
     }

     public void call(View view){
         //发送广播
         Intent intent = new Intent();
         intent.setAction("com.example.callMethod");
         sendBroadcast(intent);
     }

 }

3、实现Service

 package com.example.callmethod;

 import android.app.Service;
 import android.content.BroadcastReceiver;
 import android.content.Context;
 import android.content.Intent;
 import android.content.IntentFilter;
 import android.os.IBinder;
 import android.widget.Toast;

 public class MyService extends Service {

     private MyRecervice recervice;
     @Override
     public IBinder onBind(Intent intent) {
         // TODO Auto-generated method stub
         return null;
     }

     @Override
     public void onCreate() {
         //采用代码的方式实现广播接受者,所以不需要再清单文件中进行配置
         recervice = new MyRecervice();
         IntentFilter filter = new IntentFilter();
         filter.addAction("com.example.callMethod");//说明它接收的action
         registerReceiver(recervice, filter);
         super.onCreate();
     }

     @Override
     public void onDestroy() {
         // TODO Auto-generated method stub
         unregisterReceiver(recervice);
         recervice = null;
         super.onDestroy();
     }

     public void methodInService(){
         Toast.makeText(this, "我是服务的方法", 0).show();
     }

     private class MyRecervice extends BroadcastReceiver{
         //当接收到广播后，调用的方法
         @Override
         public void onReceive(Context context, Intent intent) {
             // TODO Auto-generated method stub
             System.out.println("我是服务内部的广播接收者，接收了广播事件");
             methodInService();
         }

     }

 }
