// simple answer for simply checking if it's VISIBLE or INVISIBLE
View.isShown()//If the image is part of the layout it might be "View.VISIBLE" but
//that doesn't mean it's within the confines of the visible screen.
//If that's what you're after; this will work:
Rect scrollBounds = new Rect();
scrollView.getHitRect(scrollBounds);
if (imageView.getLocalVisibleRect(scrollBounds)) {
// imageView is within the visible window
} else {
// imageView is not within the visible window
}
