如何使 NestedScrollView 位于 CollapsingToolbarLayout 下方?
How to make the NestedScrollView to be below the CollapsingToolbarLayout?
我是 android 编程的新手,正在制作一个导游应用程序,对于 MainActivity ,我尝试使用 CollapsingToolbarLayout 和 NestedScrollView 实现 xml 布局,但是尽管尝试了各种解决方案scrollview 仍然占据整个屏幕,我希望 NestedScrollView 成为 CollapsingToolbarLayout。我该怎么做?
下面给出了 activity_main.xml 的 xml 布局和 activity 的图像。
