Handler的另外一种用法（HandlerThread）

直接上代码：

public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        HandlerThread hThread=new HandlerThread("myThread");

        hThread.start();

        myhandler myhandler=new myhandler(hThread.getLooper());

        Message msg=myhandler.obtainMessage();

        msg.sendToTarget();//把 Message发送到目标对象，目标对象就是生成msg的目标对象。

    }

class myhandler extends Handler{

    public myhandler(Looper looper){

        super(looper);

    }

    public void handleMessage(Message msg) {

        Log.e("这是新线程", "》》》》》》》》》》》》》》》》》新线程的测试");

    }

}
