感谢http://blog.csdn.net/h3c4lenovo/article/details/7915170

方法一:

[java] view
plaincopy

package com.h3c.test;

import android.app.Activity;

import android.os.Bundle;

import android.os.Handler;

import android.os.Looper;

import android.os.Message;

import android.util.Log;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

public class HandlerTestActivity extends Activity {

Button btn;

Handler mHandler;

LooperThread thread;

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

btn = (Button) findViewById(R.id.btn);

thread = new LooperThread();

thread.start();

btn.setOnClickListener(new OnClickListener() {

public void onClick(View arg0) {

Log.e("H3c", mHandler + "==");

if (mHandler != null) {

mHandler.sendEmptyMessage(6);

}

}

});

}

class LooperThread extends Thread {

@Override

public void run() {

super.run();

Looper.prepare();

mHandler = new Handler() {

@Override

public void handleMessage(Message msg) {

super.handleMessage(msg);

Log.e("H3c", msg.what + "=");

}

};

Looper.loop();

}

}

}

方法二：

[java] view

package com.h3c.test;

import android.app.Activity;

import android.os.Bundle;

import android.os.Handler;

import android.os.HandlerThread;

import android.os.Looper;

import android.os.Message;

import android.util.Log;

thread = new HandlerThread("test_h3c");

thread.start();

mHandler = new MyHandler(thread.getLooper());

Log.e("H3c", "1:" + Thread.currentThread().getName());

btn.setOnClickListener(new OnClickListener() {

public void onClick(View arg0) {

mHandler.sendEmptyMessage(4);

}

});

}

class MyHandler extends Handler {

public MyHandler(Looper looper) {

super(looper);

}

@Override

public void handleMessage(Message msg) {

}

}
