How to implement footer in RecyclerView?

Question

Android

Hello!
Please tell me how to implement a footer with this behavior:

• If the whole screen is filled with list items - footer last
  
• If there are no elements / elements do not fill the entire screen - footer is at the bottom of the screen
  

Thank you!

Answer 1

Hello, the first thing that comes to mind is adding an empty element with height = screen height - footer height - height of all other elements, or with the help of indentation, but even here everything rests on the calculation of height.

Try to do according to this instruction, written in it - a working version. First, laying out an empty blank with your structure on it, and then using it already in a working draft, if there is one, everything will surely work out.
