RecyclerView呈现问题

Question

我想实现回收器视图布局，但我得到错误“呈现问题”。我尝试添加include，但错误仍然存在。我该如何解决问题呢？

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:background="@color/viewBg"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    tools:context="com.example.waadalkatheri.popularmovies.MainActivity"
    tools:showIn="@layout/activity_main"
    android:layout_marginTop="@dimen/activity_vertical_margin">
    <include layout="@layout/activity_main"/>

    <android.support.v7.widget.RecyclerView
        android:id="@+id/recycler_view"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:clipToPadding="false"
        android:scrollbars="vertical" />

</RelativeLayout>

错误：I

试试这个

只需从RelativeLayout中删除工具:showin=“@layout/activity_main”即可
