How to work lifecycle if load Fragment and Activity and Replace another fragment
Portrait Mode i.e (Non-rotational)
1. First, create MainActivity and one Fragment which has all lifecycle include in Fragment and Activity.
Activity lifecycle i.e.
onCreate() -> onStart() -> onResume -> onPause() -> onStop() -> onDestroyed()
↑ ↓
<---------------------- onRestart()
Fragment lifecycle i.e.
onAttach() -> onCreate() -> onCreateView() -> onActivityCreated() -> onStart() -> onResume -> onPause() -> onStop() ->
↑ ↑<----------------------------------------------↓
onDestroyed() -> onDestroyedView() -> onDetach()
If Activity and Fragment load at the same time when calling the lifecycle method i.e
Activity call- >
onCreate() ->(Activity)
then call Fragment method -> ↓
onAttach() ->(Fragment)
onCreate() -> (Fragment)
onCreateView() ->(Fragment)
onActivityCreated() ->(Fragment)
onStart() ->(Fragment)
then Activity call -> ↓
onStart() ->(Activity)
onResume() ->(Activity)
then call Fragment method -> ↓
onResume() ->(Fragment)
When user click another fragment-2 then lifecycle how to works and call method
another Fragment-2 call -> ↓
onAttach() ->(Fragment-2)
onCreate() ->(Fragment-2)
then Fragment-1 method -> ↓
onPause() ->(Fragment-1)
onStop() ->(Fragment-1)
onDestroyView() ->(Fragment-1)
onDestroyed() ->(Fragment-1)
onDettach() ->(Fragment-1)
then Fragment-2 method -> ↓
onCreateView() ->(Fragment-2)
onActivityCreated() ->(Fragment-2)
onStart() ->(Fragment-2)
onResume() ->(Fragment-2)
When the user clicks before fragment-1 then lifecycle how to works and call method
Fragment-1 call -> ↓
onAttach() ->(Fragment-2)
onCreate() ->(Fragment-2)
then Fragment-2 method -> ↓
onPause() ->(Fragment-1)
onStop() ->(Fragment-1)
onDestroyView() ->(Fragment-1)
onDestroyed() ->(Fragment-1)
onDettach() ->(Fragment-1)
then Fragment-1 method -> ↓
onCreateView() ->(Fragment-2)
onActivityCreated() ->(Fragment-2)
onStart() ->(Fragment-2)
onResume() ->(Fragment-2)
