Usage

1. Set up both EcoGallery and EcoGalleryIndicator as dependencies to your app
2. Include the EcoGalleryIndicator widget in your view. This should usually be placed adjacent to the EcoGallery it indicates.

    <LinearLayout 
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">

        <us.feras.ecogallery.EcoGallery
            android:id="@+id/images"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            app:unselectedAlpha="1" />

        <!-- Size and color are optional - you may leave them out. The default values are given below. -->
        <pl.mnowrot.ecogalleryindicator.EcoGalleryIndicator
            android:id="@+id/images_indicator"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:paddingTop="@dimen/vertical_padding_standard"
            android:layout_gravity="center"
            app:color="@android:color/background_light"
            app:size="10dp" />
    </LinearLayout>

1. In your onCreate method (or onCreateView for a fragment), first inflate the parent view and bind the indicator to the EcoGallery like this:

private void setupGalleryView(View parentView) {
	EcoGallery gallery = (EcoGallery) parentView.findViewById(R.id.images);
	Resources resources = getResources();
	// GallerySpinnerAdapter implements SpinnerAdapter (see EcoGallery docs for details)
	GallerySpinnerAdapter adapter = new GallerySpinnerAdapter(gallery.getContext(),
		resources.getDrawable(R.drawable.img0), resources.getDrawable(R.drawable.img1),
		resources.getDrawable(R.drawable.img2));
	gallery.setAdapter(adapter);
	
	// create and bind the indicator
	EcoGalleryIndicator galleryIndicator = (EcoGalleryIndicator) parentView
				.findViewById(R.id.images_indicator);
	galleryIndicator.setEcoGallery(gallery);
	// optionally set up size and color of the indicator (better do it in the XML - see above)
	galleryIndicator.setSize(resources.getDimensionPixelSize(R.dimen.10dp_size));
	galleryIndicator.setColor(resources.getColor(android.R.color.background_light));
	// optionally if you use an OnItemSelectedListener with the EcoGallery you need to set it
	// on the indicator rather than on the EcoGallery directly
	galleryIndicator.setOnItemSelectedListener(mOnItemSelectedListener);
}
