Android SwipeRefresh布局，在嵌套的ScrollView中具有RecylerView

我已经在

嵌套滚动视图

中创建了一个带有

回收视图

的片段。我正试图在应用程序中添加滑动刷新功能，但每当我在

NestedScrollView

中添加

SwipeRefreshLayout

时，列表项就会隐藏，运行中的应用程序只显示一个空白片段，下拉时也不会刷新

片段的代码：

片段作为选项卡添加到的基本布局的代码：

这里您已经有了2个可滚动的元素，并尝试添加第三个断点以获得所需的性能

SwipeRefreshLayout

与

NestedScrollview

Shoull不能一起使用。只需将

RecyclerView

与

SwipeRefreshLayout

一起使用，它就可以很好地工作

在XML文件中创建SwipeRefreshLayout和RecyclerView

    <android.support.v4.widget.SwipeRefreshLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/simpleSwipeRefreshLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">


    <android.support.v7.widget.RecyclerView
        android:id="@+id/recyclerView"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</android.support.v4.widget.SwipeRefreshLayout>

---

现在运行应用程序并下拉以刷新RecyclerView中的内容。

请包含整个布局。这样做可以防止工具栏在滚动时自动隐藏/显示。要做到这一点，我现在必须分别在上面的选项卡上上下滚动。我明白了，如果您需要保留这三个选项卡，您应该明确尝试使用swiperefreshlayout作为其他两个选项卡的包装器，而不是将其添加到nestedscrollview中

<?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="horizontal"
    android:padding="5dp">
    <!--
    items for a single row of RecyclerView
    -->
    <ImageView
        android:id="@+id/image"
        android:layout_width="70dp"
        android:layout_height="70dp"
        android:scaleType="fitXY"
        android:src="@mipmap/ic_launcher" />
    <TextView
        android:id="@+id/name"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_vertical"
        android:layout_marginLeft="10dp"
        android:text="ABCD"
        android:textColor="#000"
        android:textSize="20sp" />
</LinearLayout>
