我正在尝试制作音乐播放器。我的目标是让用户选择播放按钮，然后播放音乐，暂停然后暂停，按下一个 //mp3 player
String bob = getClass().getResource("Songs/Sing.m4a").toExternalForm();
Media lol = new Media(bob);
MediaPlayer myMedia = new MediaPlayer(lol);
//play button for mp3 player - in My Library scene
public void audioPlayerButtons(ActionEvent actionEvent) {
if (actionEvent.getSource() == playbtn) {
myMedia.play();
nowPlaying.setText("Now Playing...");
songPlayingName.setText("Sing - Ed Sheeran");
} else if (actionEvent.getSource() == stopbtn) {
myMedia.stop();
nowPlaying.setText("Stopped");
songPlayingName.setText("-");
} else if (actionEvent.getSource() == pausebtn) {
myMedia.pause();
nowPlaying.setText("Paused");
}
}
public void forwardAudio(ActionEvent actionEvent) {
if (actionEvent.getSource() == forwardbtn) {
//mp3 player
nowPlaying.setText("Now Playing...");
songPlayingName.setText("No Better - Lorde");
if (actionEvent.getSource()==forwardbtn) {
myMedia.pause();
if(actionEvent.getSource()==stopbtn){
myMedia.stop();
}
}
}
}
public void backAudio(ActionEvent actionEvent) {
if (actionEvent.getSource() == backwardbtn) {
//mp3 player
nowPlaying.setText("Now Playing...");
songPlayingName.setText("Dark Horse - Kate Perry");
}
}
按钮，它应该转到下一首歌曲，然后按上一个public class playList {
ArrayList<String> titles = new ArrayList<String>();
public String playList() throws IOException {
FileReader fr = new FileReader("Songs");
BufferedReader br = new BufferedReader(fr);
String s;
while ((s = br.readLine()) != null) {
titles.add(s);
}
fr.close();
}
}
按钮它应该回到上一首歌。
这是我播放音乐时的代码：*这只播放文件夹名称中的一首歌曲＆＃34;歌曲＆＃34;
10我制作了一个导入音乐文件，以便它读取所有音乐文件所在的文件夹并在播放列表中播放：
