CoordinatorLayout

的滚动视图行为仅适用于支持嵌套滚动的视图（exp

RecyclerView

）。默认情况下，

ExpandableListView

不支持它，因此，

CoordinatorLayout

没有正确处理

ExpandableListView

的位置

对于API>21，您可以通过以下方式获得此行为：

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {   
    setNestedScrollingEnabled(true);
}

否则，您可以切换到自定义的

RecyclerView

或。

您会遇到什么类型的错误？？？@Madhur当单击下方的设置固定高度和宽度时，下面的项目会被切断，上面的项目会出现在表格布局后面
