ActionBarSherlock animation moves position

Question

I have a menu option in my ActionBarSherlock Actionbar that kicks off an AsyncTask. I'm trying to get the icon to animate while the background task is running. I have it working, except when I click on the icon, the icon itself will "jump" a couple pixels over to the right, and it's very noticeable. Not exactly sure what is causing that to happen.

This is what I have so far:

private MenuItem refreshItem;   

private void DoRefresh() 
{
    final LayoutInflater inflater = (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    final ImageView ivRefresh = (ImageView)inflater.inflate(R.layout.refresh_view, null);

    final Animation rotation = AnimationUtils.loadAnimation(activity, R.anim.refresh);
    ImageView ivRefresh.startAnimation(rotation);

    refreshItem.setActionView(ivRefresh);

    //AsyncTask is kicked off here
}

@Override
public boolean onOptionsItemSelected(final MenuItem item) 
{
    if (item.getItemId() == R.id.refresh) {
        refreshItem = item;
        this.DoRefresh();
        return true;
    } else {
        return super.onOptionsItemSelected(item);
    }
}

refresh_view.xml

<?xml version="1.0" encoding="utf-8"?>

<ImageView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:src="@drawable/refresh"
/>

refresh.xml

<rotate
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:fromDegrees="0"
    android:toDegrees="360"
    android:pivotX="50%"
    android:pivotY="50%"
    android:repeatCount="infinite"
    android:interpolator="@android:anim/linear_interpolator"
    android:duration="1100" 
/>

UPDATE:

Been fooling around with this, with no luck. It has nothing to do with the animation because if I disable the animation, the icon still jumps over to the right. If I comment out setActionView, the icon does not jump, so it has something to do with that. Have no clue, driving me nuts.

If the menu option is an action item, you should apply the style Widget.Sherlock.ActionButton to the ImageView to keep consistency. Read this article I wrote on how to animate action items properly. http://alexfu.tumblr.com/post/19414506327/android-dev-animate-action-items
