android - 如何在Android Q中获取特定文件夹的路径

Question

我正在尝试显示保存在图库中特定文件夹中的所有图像，在Android Q getExternalStoragePublicDirectory方法已弃用且无法正常工作，如何获取Android Q中文件夹的路径？

@Override
    protected ArrayList<Photo> doInBackground(Void... voids) {
        ArrayList<Photo> photo = new ArrayList<>();
        File downloadsFolder = null;
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
            //
        } else {
            downloadsFolder = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES + "/FolderName");
        }
        Photo s;
        if (downloadsFolder != null && downloadsFolder.exists()) {
            File[] files = downloadsFolder.listFiles();
            if (files != null) {
                for (File file : files) {
                    s = new Photo();
                        s.setName(file.getName());
                        s.setUri(Uri.fromFile(file));
                        photo.add(s);
                }
            }
        }
        return photo;
    }
