Android Resume Fragment From Backstack
I have multiple fragment inside an activity.
Android resume fragment from backstack. This is fairly easy to achieve through overridePendingTransition int enterAnim int exitAnim with both 0 for no animation. Android - tutorial - remove fragment from backstack. If stackCount 0 FragmentManagerBackStackEntry backEntry fmgetBackStackEntryAtstackCount-1.
In my example this would leave the current tab on the backstack. With transaction we mean a sequence of steps to add replace or remove fragments. This new activity is added to the back stack.
Private void replaceFragment Fragment fragment String backStateName fragmentgetClassgetName. The problem is - when i launch A and then B then press back button B is removed and A is resumed. When a fragment moves downward to a lower lifecycle state the relevant LifecycleEvent is emitted to observers by the fragments view Lifecycle if instantiated followed by the fragments Lifecycle.
FragmentManager manager getSupportFragmentManager. I naturally expected the onPause method of current Fragment and onResume of new Fragment to be called. Public static Fragment getCurrentTopFragmentFragmentManager fm int stackCount fmgetBackStackEntryCount.
String fragmentTag backStateName. If fragmentPopped managerfindFragmentByTagfragmentTag null fragment not in back stack. If fmgetBackStackEntryCount 0 fmpopBackStack.
Else List fragments fmgetFragments. Fragments are useful when we want to support multiple screen size. Here is how I solved it.
