• 獲取驗證碼倒計時實例

//方式一：
Observable.interval(0L, 1L, TimeUnit.SECONDS, AndroidSchedulers.mainThread()).subscribe(new Observer<Long>() {
            @Override
            public void onSubscribe(Disposable disposable) {

            }

            @Override
            public void onNext(Long aLong) {
                 Log.e(TAG, "接收到了事件" + aLong);
                long offset = 10 - aLong;
                mTextview.setText(offset + "S");
                mTextview.setEnabled(false);
                if (offset <= 0) {
                    mDisposable.dispose();
