下拉刷新, 上拉加载更多

拖拽排序, 侧滑删除

拖拽排序, 侧滑菜单

• Example

   class DemoBaseListFragment : BaseListFragment<DealModel, DealHolder>() {
  
       //不需要设置下拉刷新\上拉加载更多的事件及逻辑, 只需要一个loadData方法
       override fun loadData() {
           //百度糯米API http://apistore.baidu.com/apiworks/servicedetail/508.html
           val url = "http://apis.baidu.com/baidunuomi/openapi/searchdeals"
           //BaseListFragment中内置的listParams, 带有page和pageSize, 也可自行定义
           val params = listParams
           params.put("city_id", 100010000)
   
           //分页请求通常需要needCallBack = true, 在请求失败时BaseListFragment会自动page--
           HMRequest.go<DealListModel>(url, params, activity = act, cache = false, needCallBack = true) {
               loadCompleted(it?.data?.deals)
           }
  
           override fun getView(parent: ViewGroup?, position: Int): DealHolder = DealHolder(getItemView(parent))
           
       }
   }
  

• UIParams

       override fun setUIParams() {
           //是否能刷新
           canRefesh = true
           //是否能加载更多
           canLoadmore = true
           //是否能拖拽排序
           canDrag = true
           //是否能侧滑
           canSwipe = true
           //侧滑方式 支持Layout(滑动菜单) Delete(滑动删除)
           swipeType = PullRefreshLoadRecyclerView.SwipeType.Layout
   
           //item的布局文件
           itemResID = R.layout.item_deal
   
           //接口定义的分页参数
           default_params_page = "page"
           default_params_pageSize = "page_size"
           //从第几页开始, 默认为1
           default_pageIndex = 1
           //每页加载多少条数据, 默认为10
           default_pageSize = 5
       }
  

• Model & Holder

       class DealListModel(errno: Int, msg: String) : BaseModel(errno, msg) {
   
           var data: DealData? = null
   
           class DealData(var total: Int, var deals: ArrayList<DealModel>? = null)
   
           //实体类中的字段个数可以与json中不同, 可以多, 也可以少, 满足需求即可
           class DealModel(var image: String, var title: String, var description: String)
       }
   
       class DealHolder(itemView: View) : BaseViewHolder<DealModel>(itemView) {
   
           override fun setContent(position: Int) {
               //进到此方法后可直接使用 data对象, 即当前绑定的数据实体
               itemView.tv_name.text = data.title
               itemView.tv_desc.text = data.description
               itemView.iv_pic.show(data.image)
           }
   
       }
