I use com.koushikdutta.ion.Ion for download image to ImageView:
void ChangeImage()
{
Ion.with(imageView).error(R.drawable.request_error).load(nextHttpUrl);
}
When begins loading next image, the current image disappears and while the next request is loading, ImageView does not contain any images (or, if I add .placeholder() - contains a picture from resources).
How I leave as placheholder current image? Or any other way that the current image on ImageView is changed only after the complete download the next?
Try
.crossfade(), that will crossfade from the existing image.
