如何根据文件夹名称在android设备中分组图像？

我对android比较陌生。目前正在处理一个Gallery应用程序。我的要求是根据文件夹名称将图像排列在设备中。我已经设法获取文件夹中的所有图像。但我无法根据文件夹名称进行排列。我面临的一个问题是，可能有更多的文件夹具有相同的名称。我将代码附加在下面。如何根据文件夹名称在android设备中分组图像？

final String[] columns = { MediaStore.Images.Media.DATA, MediaStore.Images.Media._ID }; 
      final String orderBy = MediaStore.Images.Media._ID; 
      Bitmap thumbnails[] = new Bitmap[3]; 
      String temp = null; 
      int imageCount = 0; 

      Cursor imagecursor = context.getContentResolver().query(
        MediaStore.Images.Media.EXTERNAL_CONTENT_URI, columns, null, 
        null, orderBy); 
      int image_column_index = imagecursor 
        .getColumnIndex(MediaStore.Images.Media._ID); 
      int count = imagecursor.getCount(); 
      String temparrPath = null; 
      for (int i = 0; i < count; i++) { 
       imagecursor.moveToPosition(i); 
       int id = imagecursor.getInt(image_column_index); 
       int dataColumnIndex = imagecursor 
         .getColumnIndex(MediaStore.Images.Media.DATA); 
       temparrPath = imagecursor.getString(dataColumnIndex); 
       String[] segments = temparrPath.split("/"); 
       String arrPath = segments[segments.length - 2]; 
       if (arrPath.equals(temp)) { 
        if (imageCount >= 3){ 
         imageCount++; 
         continue; 
        } 
        else { 
         thumbnails[imageCount] = MediaStore.Images.Thumbnails 
           .getThumbnail(getApplicationContext() 
             .getContentResolver(), id, 
             MediaStore.Images.Thumbnails.MICRO_KIND, 
             thumbnailOption); 
         imageCount++; 
        } 
       } else { 
        if (i != 0) { 
         Log.d(TAG, "Name = " + temparrPath); 
         adapter.putItem(temp, thumbnails, imageCount); 
         publishProgress(); 
        } 
        imageCount = 0; 
        thumbnails[imageCount] = MediaStore.Images.Thumbnails 
          .getThumbnail(getApplicationContext() 
            .getContentResolver(), id, 
            MediaStore.Images.Thumbnails.MICRO_KIND, 
            thumbnailOption); 
        temp = arrPath; 
        imageCount++; 
       } 
      } 
      Log.d(TAG, "Name = " + temparrPath); 
      adapter.putItem(temp, thumbnails, imageCount); 
      publishProgress();

有没有其他办法？

这就是我得到
