Answer 1

Okay you have no code that shows how you switch between your views but here it goes: When you switch in code in your on click or whatever you set a membervariable to last = currentselected and currentselected = the id of the selected viewflipper. Really dead simple. Oh and first time you make a check to see if its null. If you want me to be more precise supply code that shows how you switch between your views.
