问题 I am not sure what would be the correct way. I have a few calls for action for result in different fragments. Should each fragment have its own onActivityResult? Or should it all be handles in the activity's onActivityResult? 回答1: You must implement the onActityResult for every Fragment which started an activity via startActivityForResult . So, each fragment can track the result properly: The activity result makes sense only for the fragment which requested it. There's also a reason for it.

How can i achieve similar behaviour in my situation? I have this code that i wrote to try to
