How set animation-list as xml attribute

Question

Is there a way to set and start an xml animation-list as an xml attribute? I can set and start it programmatically as follows:

    ImageView img = (ImageView) findViewById(R.id.loadingImageView);
    img.setBackgroundResource(R.drawable.loading_animation);
    AnimationDrawable frameAnimation = (AnimationDrawable) img.getBackground();
    frameAnimation.start();

The animation-list is:

<animation-list xmlns:android="http://schemas.android.com/apk/res/android"
//...
android:oneshot="false" >

<item
    android:drawable="@drawable/loading_anim_frame_one"
    android:duration="50"/>
 <item
    android:drawable="@drawable/loading_anim_frame_two"
    android:duration="50"/>

etcetera.

Is there a way to do this with xml mark-up only, i.e no java code?

If not, is there a way to at least set it as an xml attribute and then start it programmatically?

I can't use rotation of a single drawable since the animation consists of several drawables in sequence.

You can declare it as

<set xmlns:android="http://schemas.android.com/apk/res/android" >

    <scale
        android:duration="700"
        android:fillAfter="false"
        android:fromXScale="0.0"
        android:fromYScale="0.0"
        android:interpolator="@android:anim/accelerate_decelerate_interpolator"
        android:pivotX="50%"
        android:pivotY="50%"
        android:toXScale="1.4"
        android:toYScale="1.4" />

    <scale
        android:duration="400"
        android:fillBefore="false"
        android:fromXScale="1.4"
        android:fromYScale="1.4"
        android:pivotX="50%"
        android:pivotY="50%"
        android:startOffset="700"
        android:toXScale="0.8"
        android:toYScale="0.8" />

</set>

Just a reference. You would have to change animation type and parameters. And as per my knowledge, you will have to start it using java.
