复制代码 代码如下:

package com.yanjun;

import android.app.Activity;

import android.os.Bundle;

import android.os.Handler;

import android.os.HandlerThread;

import android.os.Looper;

import android.os.Message;

public class HandlerActivity extends Activity {

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

// 通过HandlerThread对象来实现使用looper处理消息队列的功能

HandlerThread handlerThread = new HandlerThread("handlerThread");

// 使线程运行必须调用start()

handlerThread.start();

MyHandler myHandler = new MyHandler(handlerThread.getLooper());

Message message = myHandler.obtainMessage();

// 把message发送到myHandler.obtainMessage()目标处，即谁调用的就发送给谁

Bundle bundle = new Bundle();

// 通过bundle添加数据

bundle.putInt("age", 10);

bundle.putString("name", "john");

// 将bundle信息添加进去

message.setData(bundle);

message.sendToTarget();

}

class MyHandler extends Handler {

public MyHandler(Looper looper) {

super(looper);

// TODO Auto-generated constructor stub

}

@Override

public void handleMessage(Message msg) {

Bundle bundle = msg.getData();

int age = bundle.getInt("age");

String name = bundle.getString("name");

System.out.println("年龄" + age + "名字" + name);

}

}
