Answer 1

You should add the RecyclerView in the XML in this way:

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

</android.support.v7.widget.RecyclerView>

Hope it helps!

Answer 2

I meet this problem today. And solved it.

first step:keep the support-libs you used are same version

compile 'com.android.support:appcompat-v7:23.1.1'
compile 'com.android.support:support-v4:23.1.1'
compile 'com.android.support:recyclerview-v7:23.1.1'

second step:you should add recyclerView to your proguard files

-keep class android.support.v7.widget.** {*;}
// I`ve just keep all widgets

Answer 3

Make sure to include before you add RecyclerView to your XML

compile 'com.android.support:recyclerview-v7:22.2.0'
compile 'com.android.support:appcompat-v7:22.2.0'

If you created RecyclerView in your XML before adding these dependencies, to make it work you should remove (comment) your recycler view, build project without it and then add it back. Otherwise it still shows Inflate exception in binary XML line #n.

Answer 4

RecyclerView is not included in base Android framework, only widgets in base Android framework (like ListView, GridView etc) can be specified in layout without full namespace. RecyclerView is part of recyclerview-v7 support library.

Answer 5

1. Check reference in build.gradle
2. In your layout xml file be, write your RecyclerView component's name as a whole with its package like that android.support.v7.widget.RecyclerViewnot like RecyclerView
