The problem that the data of RecyclerView changes randomly

Question

(Image 1 & Image 2)

(Image 3)

I'm currently using the Epoxy library instead of RecyclerView. However, since Epoxy is built on the basis of RecyclerView, let's just call it RecyclerView.

Problem 1 . (Image 1 & Image 2)

When i return to another screen after entering a value in the EditText of the RecyclerView item, the entered data is moved randomly.

Problem 2 . (Image 3)

After adding enough items to be scrollable, i also enter values ​​into the EditText. And if i scroll down and come back, the data is moved to a random location.

Please tell me what is the reason and what is the proper solution.

Answer 1

Make sure you're overriding getItemViewType, getItemId and getItemCount properly.
