Nested fragments disappear during transition animation

Question

Here\'s the scenario: Activity contains fragment A, which in turn uses getChildFragmentManager() to add fragments A1 and A2

Answer 1

you can do this in the child fragment.

@Override
public Animator onCreateAnimator(int transit, boolean enter, int nextAnim) {
    if (true) {//condition
        ObjectAnimator objectAnimator = ObjectAnimator.ofFloat(getView(), "alpha", 1, 1);
        objectAnimator.setDuration(333);//time same with parent fragment's animation
        return objectAnimator;
    }
    return super.onCreateAnimator(transit, enter, nextAnim);
}
