Backport of android.transition package

[matt-oakes]

I'm currently playing around with a backport of the android.transition package. To me, this seems like a perfect fit for inclusion into NineOldAndroids to give a more complete backward compatible animation library.

If it is indeed possible to backport the transition framework all the way back to Android 1.0 (and I've not looked into it enough to know if I can) then would you consider including these into NOA itself? Another option could be to create a new library which has a hard dependency on NOA to provide pre-honeycomb support.

Let me know what you think.

A question, I tried to load something like:

<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:shareInterpolator="false" >
    <translate
        android:duration="@android:integer/config_mediumAnimTime"
        android:fromXDelta="50%p"
        android:toXDelta="0" />
    <alpha
        android:duration="@android:integer/config_mediumAnimTime"
        android:fromAlpha="0.0"
        android:toAlpha="1.0" />
</set>

But I saw that the code launches a RuntimeException on the translate element. The case is not handled by AnimatorInflator. Would your port solve it? I am definitely interested in it and I will be able to contribute.

Thanks!

I attempted to port the transition package. I had some success, but ran into a couple of issues due to two missing features: 1) ViewGroup.suppressLayout and 2) View.setTransitionAlpha. It doesn't use nine-old-androids, but could probably be modified fairly easily to use it for the animations instead.
