获取FIle路径下所有文件的地址和名称

Posted 2020-08-22 gali

 public   static  void getFileName(File[] files) {
        String address="";
        if (files != null)// 先判断目录是否为空，否则会报空指针
        {
            for (File file : files) {
                if (file.isDirectory()) {
                    getFileName(file.listFiles());

                } else {
                      String fileName = file.getName();

                        address=file.getAbsolutePath();
                       // HashMap map = new HashMap();
                        System.out.println("***address:"+address);
                    System.out.println("***name:"+fileName);
                    }

            }
        }
    }

// 获得SD卡路径   
File file1=new File(Environment.getExternalStorageDirectory()+File.separator+"AA");

 File[] files = file1.listFiles();// 读取
Utils.getFileName(files);
