CollapsingToolbarLayout＆安培; NestedScrollView不一起工作 [英] CollapsingToolbarLayout & NestedScrollView don't work together

问题描述

我试图让 Col​​lapsingToolbarLayout 与 NestedScrollView 工作，但它不遵循的滚动 NestedScrollView 正确。它移动时， NestedScrollView 到达顶部或底部一点点，但是这显然不是预期的行为。

呵呵，和 contentScrim 覆盖的ImageView 立即为好。

下面是发生了什么视频： https://youtu.be/1GlTJq5fd0U

和这里的XML：

I'm trying to make CollapsingToolbarLayout work with NestedScrollView, but it doesn't follow the scrolling of NestedScrollView correctly. It moves a little bit when the NestedScrollView reaches the top or bottom end, but that's clearly not the intended behavior.

Oh, and the contentScrim covers the ImageView immediately as well.

Here's a video of what happens: https://youtu.be/1GlTJq5fd0U

And here's the xml:

解决方案

I ended up playing around with a bunch of xml tags and don't know which one fixed the problem, but here's the last version of the xml:
