Question

The new Shared Element Transitions works when i use Fragment \'replace\' but i can\'t seem to make it work fragment \'add\'. I use the same container in bo

Answer 1

It will not animate because the old fragment is still present. For adding you need to hide the previous fragment. Here is the example

For pushing:

    fragmentTransaction.add(R.id.content, fragment);
    if (fragments.size() > 0) {
        UIBaseFragment lastElement = fragments.lastElement();
        fragmentTransaction.hide(lastElement);
    }
    fragmentTransaction.addToBackStack(null);
    fragmentTransaction.commit();
    fragments.push(fragment);

Then pop in this way

    final FragmentManager manager = getChildFragmentManager();
    manager.popBackStack();
    fragments.pop();
