点击事件防止抖动：

  /**  
	* 点击防止抖动：
    * @Author：yangtianfu
    * @Date：{2018/12/14 20:01}
    * @Description  控件防抖动，windowDuration时间内只允许点击一次
	* 可以用多次初始化点击事件的方式，设置不同条件下控件的防抖动时间
     * 讨论区开启时，1s内只能点击一次，讨论区关闭时，5s内只能点击一次
    */
RxView.clicks(bar_btn_text_live)
                .throttleFirst(windowDuration,TimeUnit.SECONDS)
                .subscribe(new Consumer<Object>() {

                    @Override
                    public void accept(Object o) throws Exception {
                        if (SPUtils.ReadInt(LiveActivity.this, "message", "message") == 100) {
                            PreLiveToast.getINSTANCE().initSinglePreLiveToast(LiveActivity.this,"管理员关闭了讨论区");
                        }else {
                            if (fl_emotionview_main.getVisibility()==View.GONE){

表单验证（账号密码同时验证）

 Observable.combineLatest(RxTextView.textChanges(editName).map(new Function<CharSequence, String>() {
            @Override
            public String apply(CharSequence charSequence) throws Exception {
                return String.valueOf(charSequence.toString());
            }
        }), RxTextView.textChanges(editPwd).map(new Function<CharSequence, String>() {
            @Override
            public String apply(CharSequence charSequence) throws Exception {
                return String.valueOf(charSequence);
            }
        }), new BiFunction<String, String, Boolean>() {
            @Override
            public Boolean apply(String s, String s2) {
                return isNameValid(s)&&isPwdValid(s2);
            }
        }).subscribe(new Consumer<Boolean>() {
            @Override
            public void accept(Boolean aBoolean) throws Exception {
                if (aBoolean){
                    btn1.setEnabled(true);
                    RxView.clicks(btn1).subscribe(new Consumer<Object>() {
                        @Override
                        public void accept(Object o) {
                            showToast("Login Success");
                        }
                    });
                }else {
                    showToast("Login Fail");
                }
            }

倒计时获取验证码

                .throttleFirst(SECOND,TimeUnit.SECONDS)//20内只允许点击一次，防止抖动
                .subscribeOn(AndroidSchedulers.mainThread())
