Double start onAnimationEnd on Android

Question

I'm trying to create a sort of slide show. For this I need to make the loop the animation with the change of the image at the end of each animation. But for whatever reason, the same event occurs twice per animation

public cPhotoSlide(Activity _activity, DBHelper _helper, int idMenu, cItemViewer _ItemViewer){
    activity        = _activity;
    helper          = _helper;
    ImageManager    = helper.ImageManager;
    ItemViewer      = _ItemViewer;
    cursor          = 0;        
    itemIds         = ChildsItemsToTable(idMenu);
    MainLayout      = (RelativeLayout) activity.findViewById(R.id.fon);
    SliderObj       = activity.getLayoutInflater().inflate(R.layout.photo_slide, MainLayout, true);
    SlideImage      = (ImageView) SliderObj.findViewById(R.id.slide_image);
    SlideImage.setImageBitmap(ImageManager.loadImage(activity.getApplicationContext(),itemIds.get(cursor)));

    animationSlide  = (AnimationSet) AnimationUtils.loadAnimation(activity.getApplicationContext(), R.anim.slide);

    animationSlide.getAnimations().get(1).setAnimationListener(
            new AnimationListener() {
                public void onAnimationStart(Animation animation) {}
                public void onAnimationRepeat(Animation animation) {}
                public void onAnimationEnd(Animation animation) {
                    Log.d(LOG_TAG,"Cursor = "+cursor+"/"+itemIds.size());
                    if (cursor >= itemIds.size()-1) {
                        cursor = 0;
                    } else {
                        cursor += 1;
                    }
                    if (itemIds.get(cursor).content != 0) {
                        SlideImage.setImageBitmap(ImageManager.loadImage(itemIds.get(cursor)));
                    }
                    SlideImage.startAnimation(animationSlide);
                }
            }
    );

    SlideImage.startAnimation(animationSlide);
}

In XML:

<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:interpolator="@android:anim/decelerate_interpolator">
    <alpha
        android:duration="250"
        android:fromAlpha="0.0"
        android:toAlpha="1.0">
    </alpha>
    <alpha
        android:startOffset="2000"
        android:duration="250"
        android:fromAlpha="1.0"
        android:toAlpha="0.0">
    </alpha>
</set>

in log:

01-30 15:52:26.700: D/cPhotoSlide(22301): Cursor = 0/207
01-30 15:52:26.716: D/cPhotoSlide(22301): Cursor = 1/207

Answer 1

Your animationset consists of two animations , and your code is being called by each one of them, to fix this you can do this:

animationSlide.getAnimations().get(1).setAnimationListener(.....);

insted of

animationSlide.setAnimationListener(.....);
