RxView.clicks(activityNewsButton)                 .throttleLast(1000,TimeUnit.MICROSECONDS)                 .subscribe(new Action1<Void>() {                     @Override                     public void call(Void aVoid) {                         System.out.println("click");                     }                 });

经过调试，这样子还是会输出很多个click，好像并没有成功防抖动，为什么
还有compoundbutton也不能实现这个功能

RxCompoundButton.checkedChanges(schoolBusSwitchButton)                 .throttleLast(1000, TimeUnit.MICROSECONDS)                 .subscribe(new Action1<Boolean>() {                     @Override                     public void call(Boolean aBoolean) {                         System.out.println("switch");                     ｝                 ｝);
