RecyclerView Rendering Issue

Question

I want to implement recycler view layout, but I am getting error "render problem". I tried to add include, but the error still exists. How can I solve the problem ?

<?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>

image the error

the error: I

have you added the recycler view dependency in your build.gradle file?? — sumit, Jul 14 '17 at 07:59

Remove this android:scrollbars="vertical" form your code and try rebuilding the project

Firstly, since you are not using CoordinatorLayout, you can safely remove the problematic app:layout_behavior="@string/appbar_scrolling_view_behavior". Read more about it here: No resource identifier found for attribute 'layout_behavior' in package

Then, I think your android:showIn xml attribute is superfluous. Get rid of it. You are recursively referring to the same activity (with include and showIn) and that's what messes up your rendering.

Search all your project with keyword: "layout_behavior" and remove all lines of them. Especially, in "content_main.xml"

ok I think I found your problem.

Just change this one line in your xml:

tools:showIn="@layout/activity_main"  to tools:showIn="@layout/activity_main.xml"

Hope it helps!!!

Well, you don't really need to add .xml after specifying the @layout/something path. Android Studio will deduce the rest itself :) – lidkxx Jul 14 '17 at 08:07

Add this to your app's build.gradle

dependencies{

         compile fileTree(include: ['*.jar'], dir: 'libs')

         compile 'com.android.support:recyclerview-v7:your_version'


       }
