No display on screen. Blank screen with only the search view appears

Question

I have no display of the data from my firebase database. Only the search view appears on top. It gives a blank screen with no error. Can someone tell me what's wrong with the code. Below is the xml, main activity and adapter class. Also I have a contractor class having all setters and getters. Is the xml in the right format as well?
