RecyclerView ClassNotFound
If you're looking for solution in 2019, you could try to change android.support.v7.widget.RecyclerView
for androidx.recyclerview.widget.RecyclerView
. It works for me. Hope it helps!
you can use androidx recyclerview widget, this works !
<androidx.recyclerview.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:scrollbars="vertical"
android:id="@+id/listExp"
/>
and import to code,
import androidx.recyclerview.widget.RecyclerView;
and then ready to use ,
private RecyclerView recyclerViewExp;
I did all what have been said in this post but nothing worked.
What did work for me:
1.Add this as say up in your build.gradle:
compile 'com.android.support:support-v4:21.0.3'
compile 'com.android.support:appcompat-v7:21.0.0'
compile 'com.android.support:recyclerview-v7:+'
compile 'com.android.support:cardview-v7:+'
2.Add the RecyclerView as a standar View and indicate the class:
<view
android:layout_width="match_parent"
android:layout_height="match_parent"
class="android.support.v7.widget.RecyclerView"
android:id="@+id/my_recycler_view"
/>
3.Then add the imports:
import android.support.v7.widget.RecyclerView;
Hope this helps!
Problem in your layout. Change
<RecyclerView
...
To
<android.support.v7.widget.RecyclerView
...
If you create RecyclerView programmatically - make sure you have proper import:
import android.support.v7.widget.RecyclerView;
