System.out.println("当前线程的id是："+Thread.currentThread().getId());
System.out.println("当前线程的名称是："+Thread.currentThread().getName());

HandlerThread htThread=new HandlerThread("myht");
htThread.start();
Handler mHandler=new Handler(htThread.getLooper()){
@Override
public void handleMessage(Message msg) {
// TODO Auto-generated method stub
//super.handleMessage(msg);
Bundle b2= msg.getData();
int age= b2.getInt("age");
String name = b2.getString("name");
Log.d("TAG", "age:" + age + ", name:" + name);
Log.d("TAG", "handler-->" + Thread.currentThread().getId());
Log.d("TAG", "handleMessage");
}
};
Message msg = mHandler.obtainMessage();
//将msg发送到目标对象，就是生成该msg的Handler对象

Bundle b = new Bundle();//使用Bundle来传递数据
b.putInt("age", 20);
b.putString("name", "John");
msg.setData(b);
msg.sendToTarget();

}
