Android四大组件Service之bindService启动

package com.example.ibcondservice02;

import android.app.Service;
import android.content.Intent;
import android.os.Binder;
import android.os.IBinder;

public class BindServiceText extends Service {  //Service 处理函数

//1.创建一个binder实例
private MyBinder binder = new  MyBinder(); // 创建一个binder类，类中能返回Service 对象（MyBinder）并创建一个实例 binder

public class MyBinder extends Binder{  // 创建一个Binder实例

public BindServiceText getService()   // 返回当前服务对象
{
return BindServiceText.this;
}

}

// 2.返回一个binder实例 ， 传入到onServiceConnected 的IBinder参数中
@Override
public IBinder onBind(Intent arg0) {  //传入到onServiceConnected 的IBinder参数中
// TODO Auto-generated method stub
return binder;   // 返回binder对象
}

public void MyMethod()  // 创建一个公共的方法
{
System.out.println("BinderService!!!");
}

}
