What are Android Fragment and their use?

  • It contains its layout and it has self behaviour with its own lifecycle.
  • It is useful for multiple activities.
  • While running activity, it can add or remove any of the fragments.
  • It includes different fragments in a single activity.
  • Furthermore, a Fragment lifecycle is added to its host activity lifecycle. While the activity stops, all remaining fragments will stop working.
  • At first, we need to decide the number of fragments to use within an activity.
  • Next, we need to create a Fragment class. It involves fragment lifecycle instances.
  • Relating to each fragment, we need to create layout files using XML files.
  • Finally, we can modify the activity file to replace the fragments according to the requirement.
