Within the Fragment lifecycle callback methods, you can declare how your Fragment behaves when it is in a certain state, such as active, paused, or stopped. Using a Fragment lifecycle is a lot like using an Activity lifecycle (see The Activity Lifecycle for details). This chapter describes the mechanisms for passing data and how to manage the Fragment lifecycle within an Activity. Understanding the relationship between Activity and Fragment lifecycles helps you design fragments that can save and restore variables and communicate with activities.Īn Activity that hosts a Fragment can send information to that Fragment, and receive information from that Fragment. Like an Activity, a Fragment has its own lifecycle.
