ThumbnailImageViewTarget

abstract class ThumbnailImageViewTarget<T> : ImageViewTarget<Z>

Avoids extra calls to requestLayout when loading more than once image into an android.widget.ImageView with fixed dimensions.

Typically it makes sense to use this class when loading multiple images with the thumbnail API into views in a scrolling list like ListView, GridView, or RecyclerView.

FixedSizeDrawable may cause skewing or other undesirable behavior depending on your images, views, and scaling. If this occurs, consider DrawableImageViewTarget or as alternatives.
