Question

I\'m trying to dynamically add and remove Fragments from a ViewPager, adding works without any problems, but removing doesn\'t work as expected.

Everytime I want to

Answer 1

i solved this problem by these steps

1- use FragmentPagerAdapter

2- in each fragment create a random id

fragment.id = new Random().nextInt();

3- override getItemPosition in adapter

@Override
public int getItemPosition(@NonNull Object object) {
    return PagerAdapter.POSITION_NONE;
}

4-override getItemId in adapter

 @Override
public long getItemId(int position) {
    return mDatasetFragments.get(position).id;
}

5- now delete code is

 adapter.mDatasetFragments.remove(< item to delete position >);
 adapter.notifyDataSetChanged();

this worked for me i hope help
