I set visibility
to invisible like this on Android:
myImageView.setVisibility(View.INVISIBLE);
And then to make it visible:
myImageView.setVisibility(View.VISIBLE);
Now I don't know if myImageView
is visible or not, how can I check it like this:
if (myImageView IS VISIBLE) {
Do something
} else {
Do something else
}
How can I do that? What do I have to write within the brackets?

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
}
You'd use the corresponding method getVisibility(). Method names prefixed with 'get' and 'set' are Java's convention for representing properties. Some language have actual language constructs for properties but Java isn't one of them. So when you see something labeled 'setX', you can be 99% certain there's a corresponding 'getX' that will tell you the value.
Or you could simply use
View.isShown()
