What is lifecycle of DialogFragment

Question

I could not find proper lifecycle of android.support.v4.app.DialogFragment by searching on Google. I need this for some implementation. As we know DialogF

Answer 1

DialogFragment does various things to keep the fragment's lifecycle driving it, instead of the Dialog. Note that dialogs are generally autonomous entities -- they are their own window, receiving their own input events, and often deciding on their own when to disappear (by receiving a back key event or the user clicking on a button).

Answer 2

DialogFragment life cycle is similar to the life cycle of fragment:. To test yourself put logs in each of the overrided methods of dialogFragment and then run your code you will understand the working of dialogFragment.

onAttach
onCreate
onCreateDialog
onCreateView
onActivityCreated
onStart
onResume

And as far as finishing or destroying dialogFragment is concerned the lifeCycle is as follows:

onPause
onStop
onDestroyView
onDestroy
onDetach

Also I believe this method will also help you know the lifecycle :

@NonNull
@Override
public Lifecycle getLifecycle() {
    return super.getLifecycle();
}

Answer 3

Strange, that if you created an AlertDialog in onCreateDialog(), didn't call onCreateView(), then onViewCreated() wouldn't also call.

See Android DialogFragment onViewCreated not called and OnCreateView not called in a dialogfragment from a fragment.
