Dot indicator resets to the first page after the activity is rotated #126

The issue is still unresolved, but I did a bit more digging. The current item of the However, I have fixed this issue by saving the current item as the original activity is being destroyed and restoring it in my private ViewPager2 mViewPager;
private SpringDotsIndicator mDotsIndicator;
@Override
protected void onCreate(final Bundle savedInstanceState) {

viewPager = findViewById(R.id.tutorial_pager);
final FragmentStateAdapter pageAdapter = new MyPageAdapter(this);

final int position = savedInstanceState.getInt("current_position");

Hello @nachogoro 👋 |
Hello, thanks for your contribution ! |
As the title states. I set the
ViewPager2
object for theSpringDotsIndicator
in theonCreate()
method of my activity, and don't do anything else with theSpringDotsIndicator
:It behaves correctly normally. However, if I'm on e.g. my third fragment and rotate the screen, when the activity is recreated the fragment shown in the new orientation is still the third one, but the dot indicates that we are on the first fragment.
As soon as I slide the fragment slightly the dot catches up and goes to the correct position.
Is this a bug or am I missing some code in order to handle these cases?
