Question

我发现RecyclerView内的RecyclerView内的GridLayot上的最后一个项目无法显示。

我尝试删除GridLayot并仅使用RecyclerView，它可以显示所有项目，但是我不能使用这些解决方案，因为我也需要显示我的AppBarLayout。因此，我需要使用GridLayot来使AppBarLayout和RecyclerView成为一个群组，并且SwipeRefreshLayout才能使用。

我该如何解决，谢谢！

使recyclerview行1

           <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" />

或使用您的布局

<RelativeLayout

android:layout_height="match_parent"
android:background="@color/colorAccent">

                    android:orientation="horizontal">

                    <ImageView

                        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"
