I am having some issues with FragmentTransactions. I have sucessfuly called on a fragment from the onClick method but the original \[code\]mainFragment\[/code\] won't "disappear" or go to back of stack. I have followed the Android Development tutorial on Fragment Transcation. I think the issue is in my \[code\]Survey.java\[/code\] class or my \[code\]Details.java\[/code\] class. Any help is appreciated. Update: (Added Photos below)
