1 | # android-drag-FowLayout
2 | this is a draggable flow layout lib (android 可拖拽的流布局库) . support android-x
3 | [Sample apk/示例app](https://github.com/LightSun/android-drag-FlowLayout/tree/master/apk)
4 |
5 | 
6 |
7 |
8 | ## 特点
9 | - 1, 类似可拖拽的GridView. 不过gridView 宽度/个数是固定的。 这个布局item宽度是不定的（放不下自动换行）。
10 | - 2，长按item拖拽，如果要处理点击事件请调用。
11 | ```java
12 |
13 | mDragflowLayout.setOnItemClickListener(new ClickToDeleteItemListenerImpl(R.id.iv_close){
14 |
15 | //点击删除成功时回调
16 | @Override
17 | protected void onDeleteSuccess(DragFlowLayout dfl, View child, Object data) {
18 | //your code
19 | }
20 | });
21 | ```
22 | - 3，可嵌套ScrollerView. demo就是。
23 | - 4, 默认均可拖拽，如果想禁止某些Item拖拽请实现 {@link IDraggable} 接口 .
24 | - 5, 支持预存储一定个数的item view. 以避免频繁创建.
25 | ```java
26 | //预存指定个数的Item. 这些Item会反复使用
27 | mDragflowLayout.prepareItemsByCount(10);
28 | ```
29 | - 6, 1.5.0 新增 拖拽状态监听器 和 view观察者。
30 | ```java
31 | //设置拖拽状态监听器
32 | mDragflowLayout.setOnDragStateChangeListener(new DragFlowLayout.OnDragStateChangeListener() {
33 | @Override
34 | public void onDragStateChange(DragFlowLayout dfl, int dragState) {
35 | System.out.println("on drag state change : dragState = " + dragState);
36 | }
37 | });
38 | //添加view观察者
39 | mDragflowLayout.addViewObserver(new IViewObserver() {
40 | @Override
41 | public void onAddView(View child, int index) {
42 | Logger.i(TAG, "onAddView", "index = " + index);
43 | }
44 | @Override
45 | public void onRemoveView(View child, int index) {
46 | Logger.i(TAG, "onRemoveView", "index = " + index);
47 | }
48 | });
49 | ```
50 |
51 | ## 使用步骤
52 | - 1, 导入下面的gradle 配置。并在xml中添加配置
53 | ```java
54 | //root gradle
55 | allprojects {
56 | repositories {
57 | maven { url "https://jitpack.io" }
58 | }
59 | }
60 | // if you use androidx . please use '1.8.8-x'
61 | implementation 'com.github.LightSun:android-drag-FlowLayout:1.8.8'
62 | ```
63 | ```java
64 |
68 |
69 | ```
70 | - 2，设置点击事件处理器 和 数据适配器.
71 | ```java
72 | //用这个处理点击事件
73 | mDragflowLayout.setOnItemClickListener(new ClickToDeleteItemListenerImpl(R.id.iv_close){
74 | @Override
75 | protected void onDeleteSuccess(DragFlowLayout dfl, View child, Object data) {
76 | //your code
77 | }
78 | });
79 |
80 | //DragAdapter 泛型参数就是为了每个Item绑定一个对应的数据。通常很可能是json转化过来的bean对象
81 | mDragflowLayout.setDragAdapter(new DragAdapter() {
82 |
83 | @Override //获取你的item布局Id
84 | public int getItemLayoutId() {
85 | return R.layout.item_drag_flow;
86 | }
87 | //绑定对应item的数据
88 | @Override
89 | public void onBindData(View itemView, int dragState, TestBean data) {
90 | itemView.setTag(data);
91 |
92 | TextView tv = (TextView) itemView.findViewById(R.id.tv_text);
93 | tv.setText(data.text);
94 | //iv_close是关闭按钮。只有再非拖拽空闲的情况下才显示
95 | itemView.findViewById(R.id.iv_close).setVisibility(
96 | dragState!= DragFlowLayout.DRAG_STATE_IDLE
97 | && data.draggable ? View.VISIBLE : View.INVISIBLE);
98 | }
99 | //根据指定的child获取对应的数据。
100 | @NonNull
101 | @Override
102 | public TestBean getData(View itemView) {
103 | return (TestBean) itemView.getTag();
104 | }
105 | });
106 | ```
107 | - 3, item管理： 对item的增删改查-,即CRUD. 通过api： mDragflowLayout.getDragItemManager()。
108 | 即可得到DragItemManager.
109 | - 4, 禁止个别Item拖拽。
110 | ```java
111 | //数据实体实现IDraggable (是否可拖拽) 接口，并且 isDraggable 为false即可
112 | private static class TestBean implements IDraggable{
113 | String text;
114 | boolean draggable = true;
115 | public TestBean(String text) {
116 | this.text = text;
117 | }
118 | @Override
119 | public boolean isDraggable() {
120 | return draggable;
121 | }
122 | }
123 | ```
124 | - 5, 如果要使用布局动画，请用ViewGroup.setLayoutTransaction(...) .
125 | - 6, 更多详情请参见[demo](https://github.com/LightSun/android-drag-FlowLayout/blob/master/Drag-FlowLayout/app/src/main/java/com/heaven7/android/drag/demo/DragFlowLayoutTest.java).
126 |
127 | ## Gradle Config
128 | ```java
129 | repositories {
130 | jcenter()
131 | }
132 | // if you use androidx . please use '1.8.8-x'
133 | compile 'com.heaven7.android.dragflowlayout:dragflowlayout:1.8.8'
134 | ```
135 |
136 | ## API说明
137 | ```java
138 | //设置拖拽状态监听器
139 | public void setOnDragStateChangeListener(OnDragStateChangeListener l)
140 | //获取拖拽状态
141 | public @DragState int getDragState()
142 | //设置Item点击事件处理器
143 | public void setOnItemClickListener(OnItemClickListener l)
144 | //设置数据适配器
145 | void setDragAdapter(DragAdapter adapter)
146 | //获取Item管理器(方便CRUD-增删改查 item)
147 | public DragItemManager getDragItemManager()
148 | //设置全局是否可拖拽。如果false,则无法长按拖拽了。
149 | public void setDraggable(boolean draggable)
150 | //设置缓存view的个数。可避免重复创建item view
151 | public void prepareItemsByCount(int count)
152 |
153 | //标记拖拽开始，这个会使得拖拽状态变更为draggable. .
154 | public void beginDrag();
155 | //标记拖拽结束, 内部会自动将拖拽状态改为 DRAG_STATE_IDLE .
156 | public void finishDrag();
157 | ```
158 |

184 | ## 一些思想
185 | - 1 ，最开始我打算用DragHelper做的。但是发现不能将拖拽的child 渲染在最上面。
186 | - 2, RecyclerView的自定义LayoutManager + onItem touch / 应该也可以.
187 |
188 |
189 |
190 | ## issue
