OnResume() is not called of the home activity when back pressed from a fragment

Question

I am working on an android application. I have cardviews for multiple fragemnts. I have put these cardviews in the main activity. So when I pressed the cardview a fragment will open. So i will make these cardviews visibility as gone. But on back press the onResume() is not called. Hence the layout is not getting visible. I tried many things but did not work. What should I do?

Answer 1

From what I understand, you have an activity with a fragment. Then you load a new fragment and then you press back. This interaction will not fire the activity's onResume() because the activity has never been stopped. If there is logic you need to perform between fragments, it needs to be somewhere else. I cannot provide any more details without some more information.
