JavaFx目錄選擇圖像和MP3並播放並顯示它們

目前我開始我的程序，然後我可以選擇一個dircetory。這些信息將打印在Textfield2上。我將這個文本複製到Textfiel1中，並添加「/textbild.png」作爲例子。那麼圖像應該顯示在另一個窗口中。與mp3相同的東西。這是我的代碼：JavaFx目錄選擇圖像和MP3並播放並顯示它們

所以我錯過了這個問題，是不是工作，或者你想要更好地做到這一點的想法？ – 2014-11-08 12:44:46

如果我選擇路徑並想要打開圖片或mp3。他們不會打開。 – 2014-11-09 12:21:22

我認爲這個問題是在這行

Image image = new Image(getClass().getResourceAsStream(TextBild)); 
.... 

InputStream thing = getClass().getResourceAsStream(Song); 
Media audioFile = new Media(thing.toString());

在變量已保存的目錄選擇所以你替換以前的代碼：

Image image = new Image("file:/"+a+TextBild); 
.... 
Media audioFile = new Media("file:/"+a+Song);

如果您在圖像和歌曲的TextField上添加路徑（例如：c：\ image \ image.png和c：\ mp3 \ song.mp3），則使用此

Image image = new Image("file:/"+TextBild); 
.... 
Media audioFile = new Media("file:/"+Song);

謝謝我解決了圖像的問題，但mp3不會播放。這是我的媒體代碼：.... Media audioFile = new Media（「file：/」+ Song）; MediaPlayer m = new MediaPlayer（audioFile）; m.play（）; ..... 可變歌曲是mp3file的目錄。 – 2014-11-09 18:12:24
