broadcast 和 service的简单结合使用

package com.ct.mytestsab;

import com.ct.mytestsab.MyService.ServiceBinder;

import android.os.Bundle;
import android.os.IBinder;
import android.app.Activity;
import android.content.ComponentName;
import android.content.Intent;
import android.content.ServiceConnection;
import android.view.Menu;

public class MainActivity extends Activity {

    private ServiceBinder binder;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Intent intent = new Intent(this,MyService.class);
        bindService(intent, connection, BIND_AUTO_CREATE);
    }
    
    private ServiceConnection connection = new ServiceConnection() {
        
        @Override
        public void onServiceDisconnected(ComponentName name) {
            // TODO Auto-generated method stub
            
        }
        
        @Override
        public void onServiceConnected(ComponentName name, IBinder service) {
            // TODO Auto-generated method stub
            binder = (ServiceBinder)service;
            int count = binder.getCount();
            System.out.println();
        }
    };

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

}
