Java 使LinearLayout具有可滚动的回收器视图

我正在开发一个应用程序，它有三个水平的RecyclerView，每个都用线性布局包装。因为它们非常大（我想再添加三个），所以我需要使视图可滚动。 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。这是我的xml：

<?xml version="1.0" encoding="utf-8"?>
<androidx.swiperefreshlayout.widget.SwipeRefreshLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/swipe_list"

    android:layout_height="match_parent">

    <LinearLayout
        android:orientation="vertical"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

我怎样才能解决这个问题？我已经在外部线性布局中修改了android:layout\u height=“wrap\u content”，但没有任何更改。

通过在外部线性布局外添加滚动视图标记解决了此问题：

<?xml version="1.0" encoding="utf-8"?>

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

            >

我希望它能对你起作用

为什么不使用滚动视图？@Dinesh而不是线性布局？
