       JAVAFX MEDIA AND MEDIAPLAYER

In this post am going to build a simple mp3 player, the functions are few just drag and drop an mp3 file and it will start playing.

The media and MediaPlayer class are easy to use, the media class takes care of the source and the MediaPlayer takes care of the controls.

Let’s first see what our mp3 looks like,

Playing the MP3

 Media media = new Media(new File("song.mp3"));//file retrieved by drag and drop event

MediaPlayer  mp=new MediaPlayer(media);

 mp.play();

//

scene.setOnDragDropped(new EventHandler<DragEvent>() {

            @Override

            public void handle(DragEvent event) {

               Dragboard db = event.getDragboard();

                boolean success = false;

               if(db.hasFiles()){

                 success=true;

                file=db.getFiles().get(0);

                 if(file.isFile() && file.getName().endsWith(".mp3")){

                        media=new Media(file.toURI().toString());

                        mp=new MediaPlayer(media);

                        mp.play();

}

}

event.setDropCompleted(success);

event.consume();

}

Volume Slider

This method sets the mediaplayer volume.//i dont recommend using this method as it is cause is not cheking if the mediaplay is null or not when adjusting the volume.Which will result in a NullPointerException.

mp.setVolume(double);

   slide.valueProperty().addListener(new ChangeListener<Number>(){

            @Override

     public void changed(ObservableValue<? extends Number>                                    observable, Number oldValue, Number newValue) {

                mp.setVolume(newValue.doubleValue());

            }

        });

The Play Button

It checks for the mediaplayer status if status is playing then pause,else if its paused play.

The variable status keeps track of the mediaplayer status.

Status status;

initilize the status in drag and drop if its an mp3 file.

 mp.setOnPlaying(new Runnable(){

       @Override

          public void run() {

                  status=mp.getStatus();//Status.PLAYING

            }

 });

play button

   play.setOnAction(new EventHandler<ActionEvent>(){

           @Override

       public void handle(ActionEvent event) {

            if(status==Status.PLAYING){

                 mp.pause();

                 play.setText("||");

                 t.setText("Paused");

                 mp.setOnPaused(new Runnable(){

                  @Override

                   public void run() {

                        status=mp.getStatus();//Status.PAUSED

                     }

                    

                 });

             }else if(status==Status.PAUSED){

                 mp.play();

                 play.setText("I>");

                 t.setText(file.getName());

                 mp.setOnPlaying(new Runnable(){

                     @Override

                     public void run() {

                       status=mp.getStatus();//Status.PLAYING

                     }

                 });

             }

}

});
