遍历文件夹~~~包含子目录

ArrayList<String> filelist = new ArrayList<String>();
    /**
     * 遍历文件夹 获取全部本地文件名
     * @param localPath
     */
    public void refreshFileList(String localPath)
    {
        File dir = new File(localPath);
        File[] files = dir.listFiles();

        if (files == null)
            return;
        for (int i = 0; i < files.length; i++)
        {
            if (files[i].isDirectory())
            {
                refreshFileList(files[i].getAbsolutePath());
            }
            else
            {
                filelist.add(files[i].getName());
            }
        }
    }
