问题 In one of my previous questions, I asked (and answered by myself following this blog post) how to properly handle key input on a RecyclerView . Now I realized that if I keep an arrow key pressed, let's say down key, the scrolling downwards stops and the RecyclerView loses its focus, probably because the scrolling is faster than the generation of all the children View s.

问题 Background I'm try to achieve something similar to what the Camera app has for its modes: I might probably not need to have a ViewPager, as seems that it uses above the horizontal list, but could be nice to have it as an option.

问题 I have gone through most of the topics related to it and couldn't find the proper solution. I am getting an error "E/RecyclerView: No adapter attached; skipping layout" when retrieving the data from firebase database to my fragments using recycler view. Please see the code below: Resources : Fragment file import android.os.Bundle; import androidx.annotation.NonNull; import androidx.fragment.app.Fragment; import androidx.recyclerview.widget.GridLayoutManager; import androidx.recyclerview
