本文整理了Java中rx.Observable.timer()方法的一些代码示例，展示了Observable.timer()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Observable.timer()方法的具体详情如下：
包路径：rx.Observable
类名称：Observable
方法名：timer

Observable.timer介绍

[英]Returns an Observable that emits a 0L after the initialDelay and ever increasing numbers after each period of time thereafter.

Backpressure Support: This operator does not support backpressure as it uses time. If the downstream needs a slower rate it should slow the timer or use something like #onBackpressureDrop. Scheduler: timer operates by default on the computation Scheduler.
[中]返回一个可观测值，该值在初始延迟后发出0L，此后的每一段时间后都会不断增加。
背压支持：该操作员不支持背压，因为它使用时间。如果下游需要较慢的速度，则应减慢计时器或使用#onBackpressureDrop之类的方法。调度程序：默认情况下，计时器在计算调度程序上运行。

@Override
  public Observable<Long> call(String s) {
    playVideo(s);
    return Observable.timer(2000, TimeUnit.MILLISECONDS);
  }
})

@Override
 public void start() throws Exception {

  //
  Scheduler scheduler = io.vertx.rxjava.core.RxHelper.scheduler(vertx);

  // Create a periodic event stream using Vertx scheduler
  Observable<Long> o = Observable.
    timer(0, 1000, TimeUnit.MILLISECONDS, scheduler);

  o.subscribe(item -> {
   System.out.println("Got item " + item);
  });
 }
}
