仿前端pagination

Android仿前端分页组件pagination

最近Android原生有个需求就是做个分页组件，不用上拉加载，因为数据量太大用户喜欢前端的方式，UI主要是拼凑比较简单，主要补充了一些判断越界和数据不全的细节，记录方便以后COPY

适配器用的万能的

maven { url 'https://jitpack.io' }

  implementation "io.github.cymchad:BaseRecyclerViewAdapterHelper4:4.1.4"

使用示例

 

   //设置监听即可pageBottomView.mOnPageNumChangeListener = object : PageBottomView.OnPageChangeListener {override fun onPageChange(page: Int, mustRefresh: Boolean) {if (mustRefresh) {mViewModel.goodsPage = pageval name = etGoodsName.text.trim().toString()mViewModel.filterList(name)}}}  fun getGoodsList(goodsName: String? = null) {ApiClient.mainService().getGoodsList(page = goodsPage,page_size = goodsSize,fuzzySearch = goodsName,goodsCategoryId = selectDishType.goodsCategoryId).enqueue(object : BaseCallBack<GoodsPage>() {override fun success(response: HttpResult<GoodsPage>) {LogUtils.logD(TAG, "getGoodsTypeList：${response.data?.data?.size}")response.data?.run {
//                        if (current_page?.toInt() == 1) {
//
//                        }// 设置最大值 接口没有则可以不显示 或者用固定值binding.pageBottomView.setPageSize(last_page, total)// 因为是前端单页分页 所以都得清除// 主页面列表更换goodsList.clear()data?.run {goodsList.addAll(this)}goodsLiveData.postValue(goodsList)}}})}
