You'd better carefully study the finished simple applet, e.g. wallet demo..

Thanks for your help. I have already studied the sample code. Now my question is that, supposed my applet is already selected. I have to send some APDUs to call my method. What is the APDU command I have to send?

That would depend on the list of commands in the applet. The standard commands are available from the ISO 7814-4 standard. Other commands would be ones that are specifically programmed into the applet.
