android - using same fragment for multiple activities

Question

I want to use a fragment in multiple activities. In the first activity i will use it in, I created it by

    final ScoreBoard fragment = new ScoreBoard();
    getFragmentManager()
            .beginTransaction()
            .add(R.id.fragment_container, fragment)
            .commit();

In the second activity, I have placed the same code in the onCreate() method. However, the fragment keeps resetting and doesn't keep its values in the second activity even though I had saved them through onSavedInstanceState() and onActivityCreated(). Am I recreating the fragment and resetting it? Thank you.

Answer 1

Yeah you can use same fragment in different activities.

Create a fragment_container view in all activities that you need to call the fragment. Then call the fragment into that container .

ex :

Activity A: calling fragment in Activity A

 final ScoreBoard fragment = new ScoreBoard();
    getFragmentManager()
            .beginTransaction()
            .add(R.id.fragment_container_activityA, fragment)
            .commit();

Activity B: calling fragment in Activity B

 final ScoreBoard fragment = new ScoreBoard();
    getFragmentManager()
            .beginTransaction()
            .add(R.id.fragment_container_activityB, fragment)
            .commit();
