问题 The setTitle() method from CollapsingToolbarLayout had some bugs already (like showing only after a scroll, fixed in v22.2.1 ). Today I updated to v23.0.0 , and it is simply not working, like no title is shown. By calling it multiple times with a delay, I can see that sometimes the title is there, but it is really not reliable (like, you switch to another fragment, then back to the first, and there's no title anymore). I found there's a new attribute, app:titleEnabled or

问题 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: <android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas
