我正在尝试使视图可滚动,其中包含滑动刷新布局。我的xml在这里

<?xml version="1.0" encoding="utf-8"?>
<androidx.core.widget.NestedScrollView 
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fillViewport="true"
    android:scrollbars="none"
    xmlns:android="http://schemas.android.com/apk/res/android">
<LinearLayout android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    xmlns:android="http://schemas.android.com/apk/res/android">

    <androidx.cardview.widget.CardView
        android:id="@+id/post"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
        <include layout="@layout/layout_post" />
    </androidx.cardview.widget.CardView>

    <androidx.swiperefreshlayout.widget.SwipeRefreshLayout
        android:id="@+id/swipe_refresh_layout_comments"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <androidx.recyclerview.widget.RecyclerView
            android:id="@+id/comment_recycler_view"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />
    </androidx.swiperefreshlayout.widget.SwipeRefreshLayout>
</LinearLayout>
</androidx.core.widget.NestedScrollView>

但是它没有显示recycler-view的内容。仅显示Cardview的内容 that answer 在不使用NestedScrollView的情况下,显示如下。它同时显示了cardivew和recyler视图的内容。但我想让我的整个屏幕都可滚动。我做错了什么? enter image description here

SwipeRefreshLayout将占据整个高度,在这种情况下,您需要将其添加为xml的父级:

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

    <androidx.core.widget.NestedScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fillViewport="true"
        android:scrollbars="none">

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

            <androidx.cardview.widget.CardView
                android:id="@+id/post"
                android:layout_width="match_parent"
                android:layout_height="wrap_content">

                <include layout="@layout/layout_post" />

            </androidx.cardview.widget.CardView>

            <androidx.recyclerview.widget.RecyclerView
                android:id="@+id/comment_recycler_view"
                android:layout_width="match_parent"
                android:layout_height="wrap_content" />
        </LinearLayout>

    </androidx.core.widget.NestedScrollView>

</androidx.swiperefreshlayout.widget.SwipeRefreshLayout>
