I have 2 path objects in my android code.I have tried all the way to check whether these paths are intersected or not, but not able to do it. How can I check whether the paths are intersected or not. Appreciate any good response, Thanks !

推荐答案

看看 Region.op

我还没有尝试过，但我建议使用:

I haven't tried it but I would suggest to use:

Region.setPath(Path path, Region clip);

从你的两个路径中获取一个区域，然后你可以使用:

to get a region from both of your paths and afterwards you can use:

if (region1.op(region2,Region.Op.INTERSECT)) {
  // intersection
}

检查交叉点...
