Move object along path with finger

Question

Following what is explained on Android move object along a path I drawed a circle path and could animate an object along it

Now I need to move the same object along the same path but using the finger. Basically it should be like a drag and drop but using the path as a guide.

How can I do such a thing?

Thanks in advance,

Answer 1

U can try to get the pixel color of the touched point, then u can check if that color matches a pre-defined path color. i had the same problem and find that very useful.
