我正面临着关于滚动协调器布局的这个问题。对于特定位置,它不会滚动购买,点击添加新按钮后,下面会添加一个列表元素。如果我们滚动该项,协调器布局的行为通常像扩展和收缩。但是当我们尝试通过触摸布局来向上滚动

我添加了一个Gif来解决问题。请看一下。 -----&gt; [gif for understanding]:https://i.stack.imgur.com/uSGfX.gif
答案 0 :(得分:2)
最后,我找到了解决方案。
我在NestedScrollView中的同一个文件中写了它,而不是包含布局。
不知何故,它奏效了。谢谢您的帮助。
<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"/>
