滚动时如何在图库中制作日期吐司？

Question

我使用网格视图创建了一个示例库应用程序，现在我想 喜欢添加一个吐司，其中包含使用moto g，

等图像创建的文件日期

Sample Image

以下是用于获取图像列表的方法，

 public static String[] getAllImages(){

String[] rootFolders = MainActivity.getStorageDirectories();    

  if (rootFolders == null) 
  {
      return rootFolders;
  }
  int rl = rootFolders.length;

  for (int i = 0; i < rl; i++)
  {
      String path = rootFolders[i];
      File target = new File(path + "/DCIM/Camera/");
      if (target.exists()) 
      {
          File[] filelists = target.listFiles();
          if(common==null)
              common = new ArrayList<File>(Arrays.asList(filelists));
          else
              Collections.addAll(common, filelists);
      }
      File target2 = new File(path + "/DCIM/100ANDRO/");
      if (target2.exists()) 
      {
          File[] filelist = target2.listFiles();
          if(common == null)
              common = new ArrayList<File>(Arrays.asList(filelist));
          else
              Collections.addAll(common, filelist);
      }
  }
  int i = common.size();
  String[] list = new String[i];
  int counter = 0;    
  String name = null;
  String path = "file:///";
  for(File file : common)
  {
        date = new Date(file.lastModified());
        if(file.isFile())
            name = path+file.getAbsolutePath().toString();
            list[counter] = name;
            mThumbIds = new Integer[counter];
            counter++;
  }
return list;}

和getview（）方法显示图像，

             String[] imagesurl = getAllImages(); 

    public View getView(int position, View convertView,
                        ViewGroup parent) {

        View view = convertView;
        final ViewHolder gridViewImageHolder;

        if (convertView == null) {

            view = getLayoutInflater().inflate(R.layout.item_grid_image, parent, false);
            gridViewImageHolder = new ViewHolder();
            gridViewImageHolder.imageView = (ImageView) view.findViewById(R.id.image);
            gridViewImageHolder.imageView.setMaxHeight(80);
            gridViewImageHolder.imageView.setMaxWidth(80);
            view.setTag(gridViewImageHolder);
        } else {

            gridViewImageHolder = (ViewHolder) view.getTag();
        }
          imageLoader.displayImage(imagesURL[position], gridViewImageHolder.imageView,options);
          return view; 
    }

提前致谢。
