Say goodbye to repeated, redundant custom Adapters , Make the developer's focus on the data, beacuse data-driven UI (告别反复、冗余的自定义Adapter，让开发者的重点落在数据上，做到数据驱动UI)

bindinglistadapter's Issues

局部刷新

大佬，对列表中的其中一项里的某个字段或者某几个字段进行局部刷新，请问有比较好的实现方式吗？整项刷新的话导致画面闪烁，不是太美观

多布局时一个bug

普通条目的第一个item没法点击, 其他的没有问题
MultiTypeAdapter:

MultiTypeAdapter(context!!, viewModel.dataSource, object : MultiTypeAdapter.MultiViewTyper {
            override fun getViewType(item: Any): Int = when (item) {
                is HomeViewModel.BannerItemViewModel -> TYPE_BANNER
                is HomeViewModel.HotKeyItemViewModel -> TYPE_HOTKEY
                else -> 0
            }
        }).apply {
            addViewTypeToLayoutMap(TYPE_BANNER, R.layout.home_item_banner)
            addViewTypeToLayoutMap(TYPE_HOTKEY, R.layout.home_item_hotkey)
            addViewTypeToLayoutMap(0, R.layout.home_item_article)
            itemDecorator = object : ItemDecorator {
                override fun decorator(
                    holder: BindingViewHolder<ViewDataBinding>,
                    position: Int,
                    viewType: Int
                ) = when (viewType) {
                    TYPE_BANNER -> {
                        val binding = holder.binding as HomeItemBannerBinding
                        binding.listener = OnBannerListener {
                            context?.toast(binding.item!!.titles[it])
                        }
                    }
                    TYPE_HOTKEY -> itemHotKeyInitView(holder.binding as HomeItemHotkeyBinding)
                    else -> {
                        itemPresenter = object : ItemClickPresenter<Any> {
                            override fun onItemClick(v: View, item: Any) {
                                when (v.id) {
                                    R.id.iv_like -> {
                                        KLog.d(viewModel.dataSource.indexOf(item))
                                        /*if (ACacheHelper.hasLogin()) {
                                            val data = item as ArticleData.DatasBean
                                            data.collect = !data.collect
                                        } else {
                                            openActivity(LoginActivity)
                                        }*/
                                    }
                                    else -> {
                                        KLog.d(viewModel.dataSource.indexOf(item))
                                    }
                                }
                            }

依次点击三个心的位置log如下:

D/HomeFragment.kt: [ (HomeFragment.kt:80)#OnItemClick ] 4
D/HomeFragment.kt: [ (HomeFragment.kt:89)#OnItemClick ] 5
D/HomeFragment.kt: [ (HomeFragment.kt:89)#OnItemClick ] 4
D/HomeFragment.kt: [ (HomeFragment.kt:80)#OnItemClick ] 4
D/HomeFragment.kt: [ (HomeFragment.kt:89)#OnItemClick ] 5
D/HomeFragment.kt: [ (HomeFragment.kt:80)#OnItemClick ] 5
D/HomeFragment.kt: [ (HomeFragment.kt:80)#OnItemClick ] 4

position 3 点不来, 但是红心有点击的selector按压效果

这个Adapter 不是继承的pagedListAdapter呀
