Performing action after fragment transaction animation is finished

Question

I want to set a buttons visibility after the animation is finished.

That\'s what calls the animation:

android.support.v4.app.FragmentTransaction fAni         


        

Answer 1

You need to subclass Fragment and override onCreateAnimator, then you can load those animations from XML and attach listeners to them.

E.g.

public class MyFragment extends Fragment
{
    @Override
    public Animator onCreateAnimator(int transit, boolean enter, int nextAnim)
    {
        final int animatorId = (enter) ? R.anim.in_anim : R.anim.out_anim;
        final Animator anim = AnimatorInflater.loadAnimator(getActivity(), animatorId);
        anim.addListener(new AnimatorListenerAdapter()
        {
            @Override
            public void onAnimationStart(Animator animation)
            {
                ...
            }

            @Override
            public void onAnimationEnd(Animator animation)
            {
               ...
            }
        });

        return anim;
   }
