问题描述
我正在开发一个将AppBarLayout与CollapsingToolbarLayout和NestedScrollView结合使用的应用程序.我已经成功实现了，并且运行正常.
I am working on an application where I'm using AppBarLayout with CollapsingToolbarLayout and NestedScrollView. I have successfully implemented this and it is working fine.
现在我想做的是，在Nestedscrollview上猛扑(快速向上滑动)时，它应该完全滚动到顶部.同样，在朝屏幕底部猛扑(快速向下滑动)时，它必须一直平稳滚动到底部.但是现在，它仅卡在两者之间，这使它看起来很难看. 我尝试了许多可用的解决方案，但对我没有任何帮助.我当前的设置如下.
Now what i am trying to do is, that on fling(fast swipe up) on the Nestedscrollview it should scroll completely to top. Similarly, on fling(fast swipe down) towards the bottom of the screen, it must scroll all the way to the bottom smoothly. However now, it only gets stuck in between which makes it look ugly. I have tried many available solutions available here but nothing worked for me. My current setup is below.

通过执行以下步骤可以改善行为:
According to which the behavior can be improved by following these steps:
1.更改
android.support.design.widget.AppBarLayout
到
me.henrytao.smoothappbarlayout.SmoothAppBarLayout and set android:id
2.删除
app:layout_behavior="@string/appbar_scrolling_view_behavior"
3.将标题添加到NestedScrollView或RecyclerView
3.Add header to your NestedScrollView or RecyclerView
实际上使它像魅力一样工作.
Which actually made it to work like charm.
最终设置如下
