even if they overlap. You always get the clicked image in the click event.
Note that a imageview always have a rect to click on. Even if you show a circle. Always the hole imageview is clickable.

For test I make and on phone I see If I click in space between circles in black space then ImageView recognizes a click. I need to know when it clicked ONLY circle, not all ImageView. I save images as png without background with transparent.

Create a canvas object for each ImageView.

You can then get the touched pixel color with Canvas.Bitmap.GetPixel(x, y). Use the color value to decide whether the user touched the shape.
