Question

我对线性布局子项有疑问

使用此布局设置，当我在RecyclerView上滚动时，我可以滚动

但是，如果我触摸并在RecycleView上方的TextView上滚动，则无法滚动布局

这是布局代码

        app:layout_anchorGravity="top|center" />


</android.support.design.widget.CoordinatorLayout>

我期望的行为是，我可以滚动触摸“ txtPhone”或“ txtAddress”或“ txtView5”以及“ reviewList”中的

有什么主意吗？

尝试将LinearLayout包装在NestedScrollView布局中。

<android.support.v4.widget.NestedScrollView 
    android:id="@+id/nestedScrollView"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
  <LinearLayout
        android:id="@+id/linearLayout"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"
        app:layout_behavior="@string/appbar_scrolling_view_behavior">
..
..
..
</LinearLayout>
</android.support.v4.widget.NestedScrollView>

某些线性布局子级无法在协调器布局内滚动
