Libgdx 如何获取目录中的文件列表?

So I am trying to get a list of files in a directory with a file handle.list() method but it returns an empty list even though there are files in the directory. What seems strange to me is that it does work on the device but it does not work on the desktop. I think I know what the problem is but I dont know how to solve it though. In the method description it says "On the desktop, an FileType.Internal handle to a directory on the classpath will return a zero length array.", but there is no other method than this so what do you guys think I can do?

推荐答案

内部文件"是在桌面运行时通过类路径找到的，所以没有简单的方法可以在类路径中列出"一个目录.如果您只是使用桌面进行开发，并且不介意一些 hack，您可以在./bin/"中搜索丢失的文件.

FileHandle dirHandle;
if (Gdx.app.getType() == ApplicationType.Android) {
   dirHandle = Gdx.files.internal("some/directory");
} else {
  // ApplicationType.Desktop ..
  dirHandle = Gdx.files.internal("./bin/some/directory");
}
for (FileHandle entry: dirHandle.list()) {
   // yadda ...
}
