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();
