固定高度的嵌套垂直RecycleView（滚动发行）

Question

我设计了这种布局布局，其中我有一个包含3 NestdScrollView的RecycleViews。在每个RecycleView项目上，单击都会出现另一个NestedRecycleView，高度在ScrollView内。 200dp滚动不起作用。在图像中，有超过4个“列表项”，但仅显示了4个，它不可滚动。当我滚动父级时，NestedRecycleView也会滚动。

[如果有人有想法，有人会说这是不好的设计如何解决这个问题也请分享您的想法。

Answer 1

将

  <?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:padding="10dp">

    <TextView
        android:id="@+id/text_view"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:textSize="20sp"
        android:layout_marginBottom="8dp"/>
    <ScrollView

        android:visibility="gone"
        android:background="@color/colorAccent"
        android:layout_height="200dp">
        <androidx.recyclerview.widget.RecyclerView
            android:id="@+id/recycle_view_nested"

            android:layout_height="wrap_content"/>

    </ScrollView>

</LinearLayout>

添加到所有RecyclerViews，并检查是否解决了滚动问题。

Answer 2

activity_main.xml

请在所有RecyclerView标签中添加recyclerView.setNestedScrollingEnabled(false); ...
