Writing customised View is good. But with this approach, is it possible to launch activities ( Here B). If B has to be made as an activity only, then this approach might fail onceagain as launching activity B will fill its content view on top of A.
The problem here is handling back key. Mahesh, once check in activity A, finish() is handled properly or not. because on close of Activity B, no need to destroy A for u.
