There's plenty of material out there on how this could be accomplished. You can override extend ButtonField and override its paint method to do what you want. You can use a BitmapField and provide the entire image for your button. Here are some links that should help:

Then for implementing navigation functionality, you need to override the navigation methods provided by Field. Such methods include Field#navigationClick(int, int) and Field#keyDown(int, int). Here's a link to the JavaDocs for Field.java.

Thank you very much.It's very helpful links. – user460397 Oct 19 '10 at 15:24 — user460397, Oct 19 '10 at 15:24
