如何知道在Android中移动一个图像时两个图像是否相交? [英] How to know if two images are intersect while one image moving in android?

问题描述

在我的应用程序中，我正在使用onTouchListener在屏幕上移动图像.

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

我在同一视图中还有另外两张图像. 我的问题是，当运动图像触摸其他任何图像时，我需要执行某些操作 (这意味着如果图像相交，则可以执行某些操作).

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).

如何实现?请尽快帮助我

How can this be achieved?.Please help me asap

预先感谢.

推荐答案

您应该能够使用Rect.intersects(Rect, Rect)，例如以下示例:

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
}
