recyclerview No adapter attached; skipping layout

Question

Just implemented RecyclerView in my code, replacing ListView.

Everything works fine. The data is displayed.

But error messages are

Answer 1

This is really a simple error you are getting, there in no need of doing any codes in this. This error occurs due to the wrong layout file used by the activity. By IDE i automatically created a layout v21 of a layout which became a default layout of the activity. all codes I did in the old layout file and new one was only having few xml codes, which led to that error.

Solution: Copy all codes of old layout and paste in layout v 21
