问题 Hey guy's First of all thanks for reading this. I'm having trouble to find a way to change my EditText when I loose focus to it.

问题 I have a RecyclerView where each row also has an EditText that allows the user to enter a value. However when the user rotates the screen the values reset to their default blank values.
