问题 How can I check whether the mediaplayer is playing or stopped, using Java Media Framework? 回答1: You can call getState and check against Controller.Started: if (mediaPlayer.getState() == Controller.Started) 回答2: // Register ControllerListener : public class myPlayer implements ControllerListener { // ....
