Handler 实现轮询的效果(自己对自己发送消息)

public static final int GET_BET_DATA = 0xabc0001;
public Handler handler = new Handler(Looper.myLooper()) {
@Override
public void handleMessage(Message msg) {
super.handleMessage(msg);
switch (msg.what) {
case GET_BET_DATA:
/**
具体操作
doRequest();
*/
break;
default:
break;
}
}
};

private  void doRequest(){

~~~~~~~~~~~省略
handler.sendEmptyMessageDelayed(GET_BET_DATA, 5000);
}
