Javafx媒体播放器 [英] Javafx Media Player

问题描述

为什么不起作用? 我尝试更改文件名，路径，但仍然无法正常工作. 我得到了很多东西. 我不知道这段代码有什么问题. 文件路径/Users/Mariusz/Music/Audio.mp3

Why it doesn't work? I tried change file name, path and still doesn't work. I get a lot of exeptions. I don't know what's wrong with this code. File path /Users/Mariusz/Music/Audio.mp3

我更改了代码，但仍然无法正常工作.

I changed my code but still doesn't work.

if(e.getActionCommand().equals("Play")) {
        bar.setString(file.getName().split(".mp3")[0]);
        playSound(file); 
}

public void playSound(File file){
    String bip = file.toURI().toString();
    Media hit = new Media(bip);
    MediaPlayer mediaPlayer = new MediaPlayer(hit);
    mediaPlayer.play();
}

推荐答案

The Media constructor takes a URI, not a file path specifier.

构造函数在JavaFX 2.2中具有以下约束:

The constructor has the following constraints in JavaFX 2.2:

• 提供的URI必须符合您当前的file.getPath()调用返回的空格字符在URI中是非法的.

  A space character, as returned by your current file.getPath() call, is illegal in a URI.

  要成为有效的URI，必须将' '编码为%20.

  To be a valid URI, a ' ' must be encoded as %20.

  要为文件构造URI，请调用 file.toURI()，而不是您当前对file.getPath()的调用.

  To construct a URI for a file, call file.toURI() instead of your current call to file.getPath().
