How to know if two images are intersect while one image moving in android?

Question

In my application, i am moving image around the screen by using onTouchListener.

I have another two images in the same view. My problem is that, when the moving image, touches any of the other images, i need to perform a certain action (that means if images are intersected, then do something).

How can this be achieved?.Please help me asap

Thanks in Advance.

You should be able to use Rect.intersects(Rect, Rect), like this example:

Rect myViewRect = new Rect();
myView.getHitRect(myViewRect);

Rect otherViewRect1 = new Rect();
otherView1.getHitRect(otherViewRect1);

Rect otherViewRect2 = new Rect();
otherView2.getHitRect(otherViewRect2);

if (Rect.intersects(myViewRect, otherViewRect1)) {
  // Intersects otherView1
}

if (Rect.intersects(myViewRect, otherViewRect2)) {
  // Intersects otherView2
}
