Android Studio not showing preview for XML layouts

Question

I am trying to create a side navigation bar and i am designing the side navigation drawer but the layout is not showing in preview. According to stack-overflows answers i tried to solve by changing app theme and cache data but none worked for me, is there anything xml attribute i am missing here? or i have to initialize it in java class? (i haven't initialized navigation bar in my java class). i am newbie in android so please help me. Here is the preview of my problem.

Answer 1

Have you tried using the side navigation drawer that comes as a default activity, You can use this to familiarise yourself with the code, hence making it simpler to make your own custom side-nav drawer.
