BottomNavigationView在CoordinatorLayout中重叠FrameLayout

Question

BottomNavigationView在CoordinatorLayout中重叠FrameLayout

hjc*_*hin 10 android coordinator-layout bottomnavigationview

以下是我的布局xml.现在的问题是BottomNavigationView与FrameLayout重叠.我希望FrameLayout延伸到BottomNavigationView的顶部.

我尝试使用技巧,例如在FrameLayout中添加paddingBottom,但我想知道是否还有其他更好的解决方案.谢谢.

您的问题有一个简单的解决方案。这是把marginBottom在FrameLayout上56dp这是根据文档height的BottomNavigationView。我不确定它是否可以根据移动屏幕进行更改。甚至文档也没有提到改变高度。我在我的一些应用程序中使用了它，但我没有发现的高度发生了BottomNavigationView变化。但以防万一。希望这会有所帮助。

将 CoordinatorLayout 和 BottomNavigationView 放在 RelativeLayout 内

使用BottomNavigation android:layout_alignParentBottom="true" 和CoordinatorLayout 布局与android:layout_above="@+id/{BottomNavigationView-ID}"

请检查以下布局
