Includes smoothly zoom, move, limit and center fix animation support, and allows easy extension so you can add your own child node's customs view and touch event detection. 9 | ```groovy 10 | dependencies { 11 | //请直接使用lib中的代码，1.0.0这个引用库很久没有更新了 12 | implementation 'androidx.dynamicanimation:dynamicanimation:1.0.0' 13 | implementation 'io.github.guaishoun:gyso-treeview:1.0.1' 14 | } 15 | ``` 16 | 17 | ### Funtions 18 | 19 | - 🍇Smoothly zoom, move 20 | - 🍈Fix your window view port 21 | - 🍉Custom your subview for special node 22 | - 🍊Custom lines between nodes 23 | - 🍋Dynamic remove nodes 24 | - 🍌Dynamic add nodes 25 | - 🥭Drag to rebuild the nodes' relationship 26 | 27 | [Releases & downloads](https://github.com/guaishouN/android-tree-view.git) 28 | 29 | > **Base--Line, LayoutManger, Custom node view** 30 | 31 | 32 | 33 | 34 | 35 | > **Add** 36 | 37 | 38 | 39 | > **Remove** 40 | 41 | 42 | 43 | > **Drag Edit Mode** 44 | 45 | 46 | 47 | > **Click** 48 | 49 | 50 | 51 | > **Zoom and Fit Window** 52 | 53 | 54 | 55 | #### Steps for use 56 | 57 | 58 | ```xml 59 | 64 | 65 | ``` 66 | 67 | Before presentation, Animal class means you own bean class, like this: 68 | 69 | ```java 70 | public class Animal { 71 | public int headId; 72 | public String name; 73 | } 74 | ``` 75 | 76 | 77 | To use a tree view, you should do **5 steps** as follows: 78 | 79 | 80 | 81 | 1. Customs adapter by extends TreeViewAdapter. 82 | 83 | ```java 84 | public class AnimalTreeViewAdapter extends TreeViewAdapter { 85 | private DashLine dashLine = new DashLine(Color.parseColor("#F06292"),6); 86 | @Override 87 | public TreeViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, NodeModel node) { 88 | //TODO in inflate item view 89 | NodeBaseLayoutBinding nodeBinding = NodeBaseLayoutBinding.inflate(LayoutInflater.from(viewGroup.getContext()),viewGroup,false); 90 | return new TreeViewHolder<>(nodeBinding.getRoot(),node); 91 | } 92 | 93 | @Override 94 | public void onBindViewHolder(@NonNull TreeViewHolder holder) { 95 | //TODO get view and node from holder, and then control your item view 96 | View itemView = holder.getView(); 97 | NodeModel node = holder.getNode(); 98 | ... 99 | } 100 | 101 | @Override 102 | public Baseline onDrawLine(DrawInfo drawInfo) { 103 | // TODO If you return an BaseLine, line will be draw by the return one instead of TreeViewLayoutManager's 104 | // if(...){ 105 | // ... 106 | // return dashLine; 107 | // } 108 | return null; 109 | } 110 | } 111 | ``` 112 | 113 | 2. configure layout manager. Space unit is dp. You can custom you line by extends {@link com.gyso.treeview.line.BaseLine} 114 | 115 | ```java 116 | int space_50dp = 50; 117 | int space_20dp = 20; 118 | //choose a demo line or a customs line. StraightLine, PointedLine, DashLine, SmoothLine are available. 119 | Baseline line = new DashLine(Color.parseColor("#4DB6AC"),8); 120 | //choose layoout manager. VerticalTreeLayoutManager,RightTreeLayoutManager are available. 121 | TreeLayoutManager treeLayoutManager = new BoxRightTreeLayoutManager(this,space_50dp,space_20dp,line); 122 | 123 | // TODO Other stable layout managers like below: 124 | // new BoxDownTreeLayoutManager(this,space_50dp,space_20dp,line); 125 | // new BoxLeftTreeLayoutManager(this,space_50dp,space_20dp,line); 126 | // new BoxUpTreeLayoutManager(this,space_50dp,space_20dp,line); 127 | // new BoxHorizonLeftAndRightLayoutManager(this,space_50dp,space_20dp,line); 128 | // new BoxVerticalUpAndDownLayoutManager(this,space_50dp,space_20dp,line); 129 | ``` 130 | 131 | 3. setting adapter and layout manager for your tree view. 132 | 133 | ```java 134 | ... 135 | treeView = findViewById(R.id.tree_view); 136 | TreeViewAdapter adapter = new AnimlTreeViewAdapter(); 137 | treeView.setAdapter(adapter); 138 | treeView.setTreeLayoutManager(treeLayoutManager); 139 | ... 140 | ``` 141 | 142 | 4. nodes data setting 143 | ```java 144 | //Create a TreeModel by using a root node. 145 | NodeModel node0 = new NodeModel<>(new Animal(R.drawable.ic_01,"root")); 146 | TreeModel treeModel = new TreeModel<>(node0); 147 | 148 | //Other nodes. 149 | NodeModel node1 = new NodeModel<>(new Animal(R.drawable.ic_02,"sub0")); 150 | NodeModel node2 = new NodeModel<>(new Animal(R.drawable.ic_03,"sub1")); 151 | NodeModel node3 = new NodeModel<>(new Animal(R.drawable.ic_04,"sub2")); 152 | NodeModel node4 = new NodeModel<>(new Animal(R.drawable.ic_05,"sub3")); 153 | NodeModel node5 = new NodeModel<>(new Animal(R.drawable.ic_06,"sub4")); 154 | 155 | 156 | //Build the relationship between parent node and childs,like: 157 | //treeModel.add(parent, child1, child2, ...., childN); 158 | treeModel.add(node0, node1, node2); 159 | treeModel.add(node1, node3, node4); 160 | treeModel.add(node2, node5); 161 | 162 | //finally set this treeModel to the adapter 163 | adapter.setTreeModel(treeModel); 164 | ``` 165 | 166 | 5. If your want to edit your tree view, please use an editor. 167 | 168 | ```java 169 | final TreeViewEditor editor = binding.baseTreeView.getEditor(); 170 | 171 | //add nodes 172 | NodeModel a = new NodeModel<>(new Animal(R.drawable.ic_13,"add-" + atomicInteger.getAndIncrement())); 173 | NodeModel b = new NodeModel<>(new Animal(R.drawable.ic_10,"add-" + atomicInteger.getAndIncrement())); 174 | NodeModel c = new NodeModel<>(new Animal(R.drawable.ic_11,"add-" + atomicInteger.getAndIncrement())); 175 | editor.addChildNodes(targetNode,a,b,c); 176 | 177 | //remove node 178 | editor.removeNode(toRemoveNode); 179 | 180 | //view center in window viewport 181 | editor.focusMidLocation() 182 | 183 | //drag to move and build new relationship 184 | editor.requestMoveNodeByDragging(isChecked); 185 | ``` 186 | 187 | 188 | 189 | 190 | #### Notes & limitations 191 | 192 | Firstly, only vertical-down derection layout and right direction layout is available, more layout style should be code. 193 | 194 | Secondly, customing lines by extends BaseLine may be a little complicate for Android beginner, and performance issues will happen if you using carefully. 195 | 196 | Finally, this custom view will be continuely improved, if you has some innovative ideas, please tell me. Thanks for you patience. 197 | 198 | I will tell you how it works on [my CSDN blogs](https://blog.csdn.net/guaisou/article/details/116611140).Thx. 199 | -------------------------------------------------------------------------------- /README_CN.md: -------------------------------------------------------------------------------- 1 | # GysoTreeView 2 | 3 | 【[中文](./README_CN.md)】【[English](./README.md)】 4 | 5 | Tree View; Mind map; Think map; tree map; 树状图；思维导图； 6 | 7 | 目前没发现比较好的Android树状图开源控件，于是决定自己写一个开源控件，对比了一下市面上关于思维导图或者树状图显示（如xMind，mind master等）的app，本文开源框架并不逊色。 8 | 9 | ### 特点 10 | 11 | - 丝滑的跟随手指放缩，拖动，及惯性滑动 12 | 13 | - 自动动画回归屏幕中心 14 | 15 | - 支持子节点复杂布局自定义，并且节点布局点击事件与滑动不冲突 16 | 17 | - 节点间的连接线自定义 18 | 19 | - 可删除动态节点 20 | 21 | - 可动态添加节点 22 | 23 | - 支持拖动调整节点关系 24 | 25 | - 增删、移动结构添加动画效果 26 | 27 | 28 | 29 | [github控件连接](https://github.com/guaishouN/android-tree-view.git) 30 | 31 | > **基础--连接线, 布局, 自定义节点View** 32 | 33 | 34 | 35 | 36 | 37 | > **添加** 38 | 39 | 40 | 41 | > **删除** 42 | 43 | 44 | 45 | > **拖动节点编辑书树状图结构** 46 | 47 | 48 | 49 | > **放缩拖动不影响点击** 50 | 51 | 52 | 53 | > **放缩及适应窗口** 54 | 55 | 56 | 57 | #### 使用步骤： 58 | 59 | 添加依赖 60 | ```groovy 61 | dependencies { 62 | //请直接使用lib中的代码，1.0.0这个引用库很久没有更新了 63 | implementation 'androidx.dynamicanimation:dynamicanimation:1.0.0' 64 | implementation 'io.github.guaishoun:gyso-treeview:1.0.1' 65 | } 66 | ``` 67 | 68 | ```xml 69 | 74 | 75 | ``` 76 | 下面说明中Animal类是仅仅用于举例的bean 77 | 78 | ```java 79 | public class Animal { 80 | public int headId; 81 | public String name; 82 | } 83 | ``` 84 | 85 | 按照以下四个步骤使用该开源控件 86 | 87 | 1 通过继承 TreeViewAdapter实现节点数据与节点视图的绑定 88 | 89 | ```java 90 | public class AnimalTreeViewAdapter extends TreeViewAdapter { 91 | private DashLine dashLine = new DashLine(Color.parseColor("#F06292"),6); 92 | @Override 93 | public TreeViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, NodeModel node) { 94 | //TODO in inflate item view 95 | NodeBaseLayoutBinding nodeBinding = NodeBaseLayoutBinding.inflate(LayoutInflater.from(viewGroup.getContext()),viewGroup,false); 96 | return new TreeViewHolder<>(nodeBinding.getRoot(),node); 97 | } 98 | 99 | @Override 100 | public void onBindViewHolder(@NonNull TreeViewHolder holder) { 101 | //TODO get view and node from holder, and then control your item view 102 | View itemView = holder.getView(); 103 | NodeModel node = holder.getNode(); 104 | ... 105 | } 106 | 107 | @Override 108 | public Baseline onDrawLine(DrawInfo drawInfo) { 109 | // TODO If you return an BaseLine, line will be draw by the return one instead of TreeViewLayoutManager's 110 | // if(...){ 111 | // ... 112 | // return dashLine; 113 | // } 114 | return null; 115 | } 116 | } 117 | ``` 118 | 119 | 2 配置LayoutManager。主要设置布局风格（向右展开或垂直向下展开）、父节点与子节点的间隙、子节点间的间隙、节点间的连线（已经实现了直线、光滑曲线、虚线、根状线，也可通过BaseLine实现你自己的连线） 120 | 121 | ```java 122 | int space_50dp = 50; 123 | int space_20dp = 20; 124 | //choose a demo line or a customs line.
