协调器布局不会向上滚动特定位置

Question

我正面临有关滚动的协调器布局问题。对于特定位置，它不会滚动购买，单击 添加新 按钮后，列表元素将添加到下方。如果我们滚动该项目，协调器布局的行为通常就像展开和收缩一样。但是当我们尝试通过触摸布局向上滚动时

我添加了一张 Gif 来说明我的问题。请看一下。 ----->[用于理解的 gif]：https://i.stack.imgur.com/uSGfX.gif

终于找到解决方法了

我没有包括布局，而是将其写在 NestedScrollView 的同一个文件中。

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"/>

协调器布局不会向上滚动特定位置

The Coordinator layout doesn't Scroll up for a specific position
