CollapsingToolbarLayout 在 ImageView 中显示填充底部
CollapsingToolbarLayout Showing padding bottom in ImageView
当 CollapsingToolbarLayout 中的 ImageView 同时使用 android:fitsSystemWindows="true" 和 android:adjustViewBounds="true" 时,它会在底部为 ImageView 提供填充
并且我发布了它的答案以帮助参考这个问题解决方案以帮助其他人解决我很久以前提出的github问题

修复你需要从根添加 android:fitsSystemWindows="true" 到每个子视图,直到你想要显示在状态栏下方的视图,然后设置 android:fitsSystemWindows="false “对于那些你想根据状态栏高度自动填充的视图,所以这将解决图像视图上的填充问题,但现在黑色渐变行为很奇怪并且达到工具栏的大小以修复我手动将填充设置为渐变在代码中使用 window 插入下面的检查代码
