Android: What's wrong with my fragment transition animation?

Question

I just need plain slide in and slide out animation for Fragment transition, below is my code: slide_in_left.xml:

<?xml version="1.0" encoding="utf-8"?>
<set
xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="true">
<translate
    android:fromXDelta="-100%"
    android:toXDelta="0%"
    android:fromYDelta="0%"
    android:toYDelta="0%"
    android:duration="700">
</translate>
</set>

slide_out_right.xml:

<?xml version="1.0" encoding="utf-8"?>
<set
xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="false">
<translate
    android:fromXDelta="0%" android:toXDelta="100%"
    android:fromYDelta="0%" android:toYDelta="0%"
    android:duration="700">
</translate>
</set>

the code I used:

SomeFragment frag = SomeFragment.newInstance(foo);
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
ft.setCustomAnimations(R.anim.slide_in_left, R.anim.slide_out_right);
ft.replace(R.id.the_fragment, frag);
ft.addToBackStack(null);

ft.commit();

The result looks very stranges, when the transition starts, the current fragment disappears without animation, the entering fragment comes(from left) like a scrolling paper. What's wrong with my animation xml code?

Thanks!

Answer 1

getSupportFragmentManager() means you are using the Compatibility Package for Fragments, I guess. I have the same problem, which is no animation happening at all.

See http://groups.google.com/group/android-developers/browse_thread/thread/5ef5ba1be9f40c56/a846578d91a032c0?hide_quotes=yes#msg_8ca017c473818a04

Google has updated the compatibility library and the transitions have been fixed. You guys should update your compatiblity library from the android sdk/avd manager.
