Interval操作符:用于创建Observable,跟TimerTask类似,用于周期性发送信息,是一个可以指定线程的TimerTask
首先添加类库
// RxAndroid compile 'io.reactivex:rxandroid:1.2.1' // RxJava compile 'io.reactivex:rxjava:1.2.4'
(1) 间隔时间3秒发送一次
private Subscription subscribe; private void start() { if (subscribe == null || subscribe.isUnsubscribed()) { subscribe = Observable.interval(3000, 3000, TimeUnit.MILLISECONDS)//延时3000 ,每间隔3000,时间单位 .observeOn(AndroidSchedulers.mainThread()) .subscribe(new Action1<Long>() { @Override public void call(Long aLong) { Log.e("1234", "执行一次"); } }); } }
(2)取消订阅
private void stop() { if (subscribe != null && !subscribe.isUnsubscribed()) { subscribe.unsubscribe(); Log.e("1234", "停止"); } }
