9 | 10 | 11 | ##### 具体思路（知识点）： 12 | 1. 异步加载相册图片； 13 | 2. 自定义相册文件夹； 14 | 3. 支持单选、多选（最多9张）图片； 15 | 4. ItemTouchHelper实现拖拽、排序、删除； 16 | 5. 对Canvas画布操作、变换，结合属性动画，实现图片的放大、缩小等； 17 | 18 | **详细看代码怎么实现的！！！** 19 | 20 | **License** 21 | 22 | Copyright 2019 StevenYan88 23 | 24 | Licensed under the Apache License, Version 2.0 (the "License");
