我有一个底部的表格,里面有一个 NestedScrollView(见下文)。当我按下 FAB 按钮时,我想让这个 NestedScrollView 中的某些部分不可见。但是当我将一些线性布局的可见性更改为 GONE 时,底页会从顶部飞走。看这里:
您可以从https://github.com/Tanrikut/BottomSheetExample获取整个代码
我的更改可见性方法:
private void changeVisibility() {
subtitleLayout.setVisibility(View.GONE);
coordinateLayout.setVisibility(View.GONE);
timeLayout.setVisibility(View.GONE);
}
我的 NestedScrollView xml:
