Passing data between ActivtyPrior to learning how to start an activity, in some cases not only need to start another activity, but also to get the results returned. And sometimes more often when you start another activity with some values.1. Define a intent and specify the activity that will be started for the intent2. Call Startactivityforresult (Intent intent,int Requestcode) to jump and Mark Requestcode3. Rewrite onactivityresult (int requestcode,int resultcode,intent data) to parse the retur
