Dynamically: FragmentManager is used to embed fragments with activities that enable the addition, deletion, or replacement of fragments at run time.This type of fragment can not be replaced during the run time. Statically: Explicitly mention the fragment in the XML file of the activity.Multiple fragments can be added to one activity. If you can replace B with A without Losing resources.įragments are always embedded in Activities i.e., they are added to the layout of activity in which they reside. It will call when your fragment Destroy(app crash or attach new fragment with existing fragment)Ĭonsider Fragment-1 is A and Fragment-2 is B and A is attached to the Main ActivityĢ. The system executes this method to disassociate the fragment from its host activity. It is called to perform the final clean up of fragment’s state and its lifecycle. It will call when you can attach new fragment and destroy existing fragment Resoruce System calls this method to clean up all kinds of resources as well as view hierarchy associated with the fragment. Method to terminate the functioning and visibility of fragment from the user’s screen. System call this method to commit the changes made to the fragment. It indicates that the user is leaving the fragment. This method is called to make the visible fragment interactive. The system invokes this method to make the fragment visible on the user’s device. View hierarchy of the fragment also instantiated before this function call. It indicates that the activity has been created in which the fragment exists. You should inflate your layout in onCreateView but shouldn’t initialize other views using findViewById in onCreateView. The root of the fragment’s layout is returned as the View component by this method to draw the UI. System calls this method to create the user interface of the fragment. This method initializes the fragment by adding all the required attributes and components. When we attach fragment(child) to Main(parent) activity then it call first and then not call this method any time(like you run an app and close and reopen) simple means that this method call only one time. This method executes only once during the lifetime of a fragment. The very first method to be called when the fragment has been associated with the activity.
