I am having a similar issue, where I use onCreateDialog(int) inside I use AlertDialog.builder to build my dialogbox depending on what the int is, and then I use builder.show. However onCreateDialog is only called by onTouch(motionevent) but If I rotate the screen after calling createDialog(2) it will seeminly call itself. I have stepped through the code an oncTouchis never called. I have tried calling dialog.dismiss() in the onClick method that is inside onCreateDialog but it doesn't work.
