Hiding a small line in a RecyclerView ItemTouchHelper

I'm new on Android studio. I made a RecyclerView with a list of data, and I implemented the event on Swiped with an ItemTouchHelper. When I swipe a child from the right to the left I see a small line like in the photo
I would hide this small line. What properties or element of the RecyclerView can be?

try setting onFocusChanged listener to edittext.

Did you mean that, when you click on custom TextView, your convertView's OnClickListener didn't called onClick()?
If yes, you could try disable the custom TextView.
