使用 Recycler View 使 LinearLayout 可滚动
[英]Make LinearLayout with Recycler View scrollable
问题描述
I'm trying to develop an app which has three horizontal RecyclerView, each one wrapped in a Linear Layout.
我正在尝试开发一个应用程序，它具有三个水平 RecyclerView，每个都包裹在一个线性布局中。 Since they are pretty large (and I'm thinking to add three more of them) I need to make the view scrollable.由于它们非常大（我想再添加三个），我需要使视图可滚动。 The last row is shown incorrectly and I cannot scroll the list to view the cards as on the top two rows.最后一行显示不正确，我无法滚动列表以查看前两行的卡片。 This is my xml:这是我的 xml：
<?xml version="1.0" encoding="utf-8"?>

How can I solve?我该如何解决？ I already modified android:layout_height="wrap_content" in the external LinearLayout but nothing changed.我已经在外部 LinearLayout 中修改了android:layout_height="wrap_content"但没有任何改变。

Solved by adding a ScrollView tag outside the external LinearLayout:通过在外部 LinearLayout 之外添加 ScrollView 标签解决：

if ScrollView did not work you can use androidx.core.widget.NestedScrollView如果ScrollView不起作用，您可以使用androidx.core.widget.NestedScrollView
<androidx.swiperefreshlayout.widget.SwipeRefreshLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/swipe_list"
android:layout_width="match_parent"

<androidx.core.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="8dp"
