GridLayout 中的 RecyclerView 无法显示最后一项

Question

我发现 RecyclerView 中的最后一项在 GridLayot 中的 RecyclerView 时无法显示。

我尝试删除 GridLayot 并只使用 RecyclerView，它可以显示所有项目，但我不能使用这些解决方案，因为我也需要显示我的 AppBarLayout .所以我需要用GridLayot把AppBarLayout和RecyclerView做一个组，SwipeRefreshLayout可以用

我该如何解决，谢谢！

将 recyclerview 设为第 1 行

           <androidx.recyclerview.widget.RecyclerView
             android:layout_row="1"
            android:id="@+id/activity_cost_diamond_history_recycler"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:scrollbars="vertical" />

或者像这样使用你的布局

<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/colorAccent">


<androidx.swiperefreshlayout.widget.SwipeRefreshLayout
    android:id="@+id/activity_cost_diamond_history_swipe_refresh"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/colorPrimary">

    <LinearLayout
        android:orientation="vertical"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
        <GridLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:columnCount="1"
            android:rowCount="1">

            <com.google.android.material.appbar.AppBarLayout
                android:layout_width="match_parent"
                android:layout_height="50dp"
                android:layout_marginTop="15dp"
                android:layout_marginBottom="15dp"
                android:layout_row="0">

                <LinearLayout
                    android:layout_width="wrap_content"
                    android:layout_height="50dp"
                    android:layout_gravity="center"
                    android:gravity="center"
                    android:orientation="horizontal">

                    <ImageView
                        android:id="@+id/activity_cost_diamond_history_user_cost_diamond_icon"
                        android:layout_width="30dp"
                        android:layout_height="30dp"
                        android:layout_marginRight="5dp"
                        android:src="@drawable/ic_back" />

                    <TextView
                        android:id="@+id/activity_cost_diamond_history_user_cost_diamond_text"
                        android:layout_width="wrap_content"
                        android:layout_height="50dp"
                        android:gravity="center"
                        android:textColor="@color/background"
                        android:textSize="17sp" />

                </LinearLayout>

            </com.google.android.material.appbar.AppBarLayout>



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


</androidx.swiperefreshlayout.widget.SwipeRefreshLayout>
