Recyclerview 不显示或滚动片段

Question

我在这里发现了一些关于此问题的问题，但其中 none 帮助解决了我的问题。 Recycler 视图工作正常，但棒棒糖版本存在问题。它在 activity 中完美运行，但在片段内部使用时不显示或滚动。我的片段屏幕显示为空白，但回收器视图适配器中的点击侦听器正在工作。当我将片段代码迁移到 activity 时，它运行良好。我正在使用 28.0.0 这是我的 xml 代码。

<?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="match_parent"
android:orientation="vertical">

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

<android.support.v4.widget.SwipeRefreshLayout
    android:id="@+id/swipeToRefresh"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">

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

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

            android:background="@color/white"
            android:nestedScrollingEnabled="false" />

    </FrameLayout>

Answer 1

该死的！在这个问题上卡了整整两天后，我终于找到了解决方案。这是因为我在 activity 中添加片段时使用了 FragmentTransaction.TRANSIT_FRAGMENT_FADE。删除过渡解决了我的问题

Recyclerview 不显示或滚动片段
