如何使用ViewPropertyAnimation制作从右到左的翻译动画？

Question

I am trying to show a fragment with right to left animation, as though it is coming from the right side of the screen but my code does exactly the opposite.

flBackground.animate().setDuration(250).x(0).translationX(0).alpha(1).start();

flBackground here is the id of the root view in my fragment.

I played with 'translationX' method. I gave the screen width in pixels, but my fragment got off screen. Is there a way in ViewPropertyAnimation that I can set initial positioning of a view to animate from?

I only want to use ViewPropertyAnimation, not other Animation objects. Other ones are quite big and I want simple code for my project.

You can use FragmentTransaction.setCustomAnimations() . It's the best way.

Example:

getFragmentManager().beginTransaction()
        .setCustomAnimations(R.animator.slide_right, R.animator.slide_left)
        .add(R.id.list_fragment_container, YourFragment.instance())
        .commit()
