代码[github地址](https://github.com/drawthink/ExpandableRecyclerView) 2 | 3 | 4 | 1.目前只支持两级结构。 5 | 6 | 2.支持所有组同时全部展开，支持同一时间只能展开一组。 7 | 8 | 3.GroupView,ChildView高度自定义。 9 | 10 | 4.支持初始化数据时，指定展开某组数据。 11 | 12 | 5.支持GroupItem,ChildItem的Onlick,OnLongClick事件。 13 | 14 | 6.展开收起带动画。 15 | 16 | 17 | 效果图： 18 | 19 | ![](https://github.com/drawthink/ExpandableRecyclerView/blob/master/screenshot/screenshot.gif?raw=true) 20 | 21 | 使用步骤：加入依赖 22 | ``` 23 | compile 'com.drawthink:expandable-recyclerview:0.0.3' 24 | 25 | ``` 26 | 1.继承BaseViewHolder，实现自己的ViewHolder 27 | 28 | 1.1 在构造函数中初始化你的View(包括GroupView,和childView). 29 | 30 | 1.2 分别实现以下两个方法，并在对应方法中返回对应Layout布局文件中根节点的ID。 31 | 32 | ``` 33 | public int getGroupViewResId() 34 | 35 | public int getChildViewResId() 36 | ``` 37 | 示例代码： 38 | ``` 39 | public class ImageViewHolder extends BaseViewHolder { 40 | 41 | public ImageView image; 42 | public TextView tvTitle; 43 | 44 | /** 45 | * 初始化你的View(这里包括GroupView,和childView) 46 | */ 47 | public ImageViewHolder(Context ctx, View itemView, int viewType) { 48 | super(ctx,itemView, viewType); 49 | image = (ImageView) itemView.findViewById(R.id.iv_image); 50 | tvTitle = (TextView)itemView.findViewById(R.id.tv_title); 51 | } 52 | 53 | /** 54 | * @return 返回你的GroupView 布局文件中根节点的ID 55 | */ 56 | @Override 57 | public int getGroupViewResId() { 58 | return R.id.group; 59 | } 60 | 61 | /** 62 | * @return 返回你的ChildView 布局文件中根节点的ID 63 | */ 64 | @Override 65 | public int getChildViewResId() { 66 | return R.id.child; 67 | } 68 | 69 | } 70 | ``` 71 | 72 | 2.继承BaseRecyclerViewAdapter ，完成自己的Adapter。 73 | 74 | T,S,VH各参数见如下注释 75 | ``` 76 | /** 77 | * author：Drawthink 78 | * describe: 79 | * date: 2017/5/22 80 | * T :group data 81 | * S :child data 82 | * VH :ViewHolder 83 | */ 84 | 85 | public abstract class BaseRecyclerViewAdapter extends RecyclerView.Adapter 86 | 87 | ``` 88 | 示例Adapter代码： 89 | ``` 90 | public class ImageAdapter extends BaseRecyclerViewAdapter { 91 | 92 | private Context ctx; 93 | private List datas; 94 | private LayoutInflater mInflater; 95 | 96 | public ImageAdapter(Context ctx, List datas) { 97 | super(ctx, datas); 98 | mInflater = LayoutInflater.from(ctx); 99 | this.ctx = ctx; 100 | this.datas = datas; 101 | } 102 | 103 | @Override 104 | public void onBindGroupHolder(ImageViewHolder holder, int groupPos,int position, String groupData) { 105 | holder.tvTitle.setText(groupData); 106 | } 107 | 108 | @Override 109 | public void onBindChildpHolder(ImageViewHolder holder, int groupPos,int childPos,int position, ImageBean childData) { 110 | holder.image.setBackgroundResource(childData.getResId()); 111 | } 112 | 113 | @Override 114 | public View getGroupView(ViewGroup parent) { 115 | return mInflater.inflate(R.layout.title_item_layout,parent,false); 116 | } 117 | 118 | @Override 119 | public View getChildView(ViewGroup parent) { 120 | return mInflater.inflate(R.layout.item_image_layout,parent,false); 121 | } 122 | 123 | @Override 124 | public ImageViewHolder createRealViewHolder(Context ctx, View view, int viewType) { 125 | return new ImageViewHolder(ctx,view,viewType); 126 | } 127 | } 128 | ``` 129 | 130 | 完成以上两步之后，基本大工告成，由于ExpandableRecyclerView的数据是要分组的，所以提供了RecyclerViewData来封装 131 | ``` 132 | /** 133 | * @param groupData 134 | * @param childDatas 135 | * @param isExpand 初始化展示数据时，该组数据是否展开 136 | */ 137 | public RecyclerViewData(T groupData, List childDatas,boolean isExpand) 138 | 139 | ``` 140 | 那接下来看下数据具体是怎样封装的。 141 | ``` 142 | mDatas = new ArrayList<>(); 143 | List bean1 = new ArrayList<>(); 144 | List bean2 = new ArrayList<>(); 145 | List bean3 = new ArrayList<>(); 146 | // 每个子列表长度可以不相同 147 | bean1.add(new ImageBean("Dog", R.mipmap.dog)); 148 | bean1.add(new ImageBean("Dog", R.mipmap.dog)); 149 | bean2.add(new ImageBean("Cat", R.mipmap.cat)); 150 | bean3.add(new ImageBean("Bird", R.mipmap.bird)); 151 | 152 | mDatas.add(new RecyclerViewData("Dog", bean1, true)); 153 | mDatas.add(new RecyclerViewData("Cat", bean2, true)); 154 | mDatas.add(new RecyclerViewData("Bird", bean3, true)); 155 | ``` 156 | 所有工作以完成，现在你可以象平常使用Adapter，RecyclerView一样，来愉快的写代码了。 157 | 158 | 注意：在对元数据mDatas进行增删操作时，要调用adapter.notifyRecyclerViewData();否则会造成数据索引错乱的问题。 159 | 160 | 161 |
