How to check View null condition in xamarin.android












0















I am working on xamarin.android application. I have a statement as below



 View photoresponse =_questionTypesModel.QuestionTypesContent.FindViewWithTag( Convert.ToString(questionType["id"]));


here I need to check the null condition for photoresponse, When I am trying to check as if(photoresponse ==null) always returns true.



 QuestionTypesContent


This is a `Linearlayout

  • You are checking correctly. Probably your view is always null.

  • My guess would be that the view tagged with the string is not in the view hierarchy: developer.android.com/reference/android/view/… We would need to see more code to figure out why that is.

  • Thanks for both the suggestions. I found finally it is the tags issue and I solved them
