LegacyBarFragmentActivity

Hello! I'm already confused from trying to find the solution and test the solutions I found on Google, I decided to ask for help.

The source code posted below works perfectly, but need to get the value held in this variable strEmpresa = Intent.GetStringExtra ("strEmpresa").ToString (); CabecalhoTab class and assign the line view.FindViewById <TextView> (Resource.Id.fragment_text).Text = strEmpresa;
Does anyone know how to do this? Help!
