android - how to hide fragment(in FrameLayout) and show viewpager fragment? -
i having activity contains viewpager,tablayout , navigationdrawer. navigation drawer contains items(say 10). got framelayout load fragments when navigation drawer items clicked.
here in viewpager got 3 fragments(say breakfast,lunch,dinner). in navigation drawer list items got same items in viewpager.
now when click first 3 items viewpager fragments works fine.after clicking fourth item in drawer(i.e check calories) check calories fragment of framelayout loaded successfully.now when click breakfast,lunch or dinner item,the viewpager fragment not loading replacing framelayout fragment. come solution.
here code
