简单实用Handler传递数据并且更新UI界面

1.在Activity中

private Handler mHandler = new Handler(){

public void handleMessage(Message msg){

super.handleMessage(msg);

switch(msg.what){

case 1:

//xxxx

resultMap = (Map<String,Object>)msg.getData().getSerialzable("value");

fillView(resultMap);

break;

default:

break;

}

}

};

2.在Activity中

class MyThread implements Runnable{

public void run(){

Message msg =  new Message();

msg.what=1;

Bundle mBundle = new Bundle();

mBundle.putSerializable("value",(Serialzable)map);

msg.setData(mBundle);

msg.obj = "hahahaha";

mHandler.sendMessage(msg);

}

}

3.在OnCreate()中：

new MyThread().start();
