I'm trying to get my replaced fragment to appear in the detail fragment but after debugging my app on a tablet emulator and selecting the necessary list view item, the log cat gives me this error:
Caused by: java.lang.IllegalArgumentException: No view found for id 0x7f0c0050 (com.apptacularapps.exitsexpertlondonlite:id/detail_container) for fragment FragmentWCBank{3b4ea8fb #0 id=0x7f0c0050}
I really don't understand why I'm getting this error when my fragment is there within my project. Does anyone know what I'm doing wrong and how to fix this?

Undesired result
Your code transaction.replace(R.id.
detail_container
...Now this may be the correct UI element. I am assuming this is the correct UI. If so,fragment_wc_bank
layout xml does not have that IDdetail_container
, hence you get error, simple as that. However activity_main.xml has that ID, again I am assumingdetail_container
is the correct UI that you want.Suggested code FROM:
