-------------------------------------------------------------------------------- 1 | # TreeView 2 | 这是一个功能多样的自定义树形列表，在使用RecyclerView实现树形列表，并在其基础上附加了一些额外功能。 3 | 4 | **基本功能：** 5 | - 展开收拢，收拢后保持子节点展开收拢状态（1.0.1实现） 6 | - 响应点击事件（1.0.1实现） 7 | 8 | **附加功能：** 9 | - 自定义每个节点的布局，自定义每个节点所保存的数据（1.1.0实现） 10 | - 选中功能，响应选中事件，可设置选中子节点后是否选中父节点（1.1.0实现） 11 | - 全部展开（展开列表中数据，不响应节点展开事件）和全部收拢功能（1.1.0实现） 12 | - 将展开收拢细分成（1.2.0实现）： 13 | - 点击展开收拢后事件响应toggleClick（可在此请求该节点下孩子节点数据，并添加到当前结点下） 14 | - 列表展开或收拢toggle 15 | - 展开后事件响应toggled（节点箭头旋转等） 16 | 17 | ## 添加依赖 18 | 仓库 19 | ``` 20 | allprojects { 21 | repositories { 22 | ... 23 | maven { url 'https://jitpack.io' } 24 | } 25 | } 26 | ``` 27 | ([最新版本](https://github.com/q1113225201/TreeView/releases/latest)) 28 | 29 | ``` 30 | compile
