android - fragment navigation drawer items not displaying -

-

i'm working material design , reason navigation drawer not displaying drawer items. think may have below:

enter image description here

my gradle looks normal well.

dependencies { compile filetree(dir: 'libs', include: ['*.jar']) compile 'com.android.support:recyclerview-v7:+' compile "com.android.support:appcompat-v7:22.1.0" }

recyclerview needs layoutmanager, have added this?

recyclerview.setlayoutmanager(new linearlayoutmanager(context));

if still not work, try invalidate cache , restart in android studio. if still not work have download , install recent version of android studio , work.
