I’m developing an android application. It is an exam app. When a user clicks an answer, the application changes the layout with $setContentView(); in same activity.
But it gives an error for layout Caused by: java.lang.NumberFormatException: unable to parse ‘@2131230721’ as integer

My layout file is below, if you need I can put my project myserver. And I can paste my activity code, but it’s a basic setContentView() only. I guess one of my id’s is causing the error but i couldn’t find it.
