本文实例为大家分享了Android实现轮询的方式，供大家参考，具体内容如下

1.通过rxjava实现(代码中使用了Lambda表达式)

private static final int PERIOD = 10 * 1000;private static final int DELAY = 100;private Disposable mDisposable;/** * 定时循环任务 */private void timeLoop() { mDisposable = Observable.interval(DELAY, PERIOD, TimeUnit.MILLISECONDS) .map((aLong -> aLong + 1)) .subscribeOn(Schedulers.io()) .observeOn(AndroidSchedulers.mainThread()) .subscribe(aLong -> getUnreadCount());//getUnreadCount()执行的任务}//关闭定时任务if (mDisposable != null) mDisposable.dispose();

2.通过Handler实现

private Handler mHandler = new Handler(Looper.getMainLooper()); // 全局变量private Runnable mTimeCounterRunnable = new Runnable() { @Override public void run() {//在此添加需轮寻的接口getUnreadCount();//getUnreadCount()执行的任务 mHandler.postDelayed(this, 20 * 1000); }};//关闭定时任务mHandler.removeCallbacks(mTimeCounterRunnable);

3.使用Java的Timer和TimerTask实现

private static final int PERIOD = 10 * 1000;private static final int DELAY = 100;private Timer mTimer;private TimerTask mTimerTask;private void timeLoop2(){ mTimer = new Timer(); mTimerTask = new TimerTask() { @Override public void run() { //在此添加轮询 } }; mTimer.schedule(mTimerTask,DELAY,PERIOD);}//关闭定时任务if (mTimer != null) mTimer.cancel();
