推荐答案
最后，我找到了解决方案.
Finally, I found the solution.
我没有包含布局，而是在NestedScrollView的同一文件中编写了它.
Rather than including the layout, I wrote it in the same file within NestedScrollView.
以某种方式起作用.谢谢您的帮助.
Somehow it worked. Thanks for the help.
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
app:layout_behavior="@string/appbar_scrolling_view_behavior"/>
