I have a problem with RecyclerView.
When I fill my descTextView to my adapter file. DescTextView Scrool is not working. I want to scrool just text in descTextView.
If i change layout_height to match_parent in item_detail_view.xml then all pages starts to scroll. But I dont want it.
Here is my codes. What is wrong
Sometimes scroll is working and lost how is work I dont know.
I tried some codes bu I dont find the problem.
//fragment_home.xml
<?xml version="1.0" encoding="utf-8"?>

android:layout_height="match_parent"
