can you please suggest some idea, so that i can use that in my开发者_JAVA百科 application. thnQ

What you need is a pathfinding algorithm to determine the path. If you want an efficient and pretty standard algorithm, there is an algorithm called A* for finding the best path between two places. It's a subject by itself.

Here is a nice tutorial to understand the algorithm: Link

And you can also google "a star pathfinding", and you'll find a lot on the subject.
