在我的android应用程序中，我使用recyclerview和ScrollView创建了时间表结构。下面是我的时间表。 enter image description here

在recyclerview中，周期表既是侧面标题，又是日期列表是最高标题。下面是我的代码。

xml：

}

在这里，当我水平移动日列表标题时，时间表也会随之滚动，反之亦然，并且它不会隐藏以下时间段列表。 enter image description here

但是当我垂直滚动时段列表或时间表时，它将隐藏或滚动日列表标题。是否有任何方法可以使时间表或时段列表垂直时固定或可见日列表。

更新：

最后，我注意到的一件事是onScrollChanged（）函数仅适用于水平滚动视图（即.ObservableHorizo​​ntalScrollView），而不适用于垂直滚动视图（即.ObservableScrollView）。下面是该函数，不适用于我认为它由于父NesstedScrollview而无法正常工作。

public void onScrollChanged(ObservableScrollView scrollView, int x, int y, int oldx, int oldy) {
        if (scrollView == this.scrVwC) {
            this.scrVwD.scrollTo(x, y);
        } else if (scrollView == this.scrVwD) {
            this.scrVwC.scrollTo(x, y);
        }
    }
