android在滚动端动态加载Listview的最佳实践？

implementation 'androidx.recyclerview:recyclerview:1.2.1'
implementation 'androidx.paging:paging-runtime:3.0.0'

class MyDataSource : PagingSource<Int, Item>() {
    override suspend fun load(params: LoadParams<Int>): LoadResult<Int, Item> {
        // 从网络或数据库中加载数据
        // 返回LoadResult.Page对象，包含加载的数据和下一页的键（key）
    }
}

val pagingConfig = PagingConfig(
    pageSize = 20, // 每页加载的数量
    prefetchDistance = 10, // 预加载的距离
    enablePlaceholders = false // 是否启用占位符
)

val pager = Pager(
    config = pagingConfig,
    pagingSourceFactory = { MyDataSource() }
)
val pagingData: Flow<PagingData<Item>> = pager.flow

class MyAdapter : PagingDataAdapter<Item, MyViewHolder>(diffCallback) {
    // 实现ViewHolder的创建和数据绑定逻辑
}

val recyclerView: RecyclerView = findViewById(R.id.recyclerView)
val adapter = MyAdapter()
recyclerView.adapter = adapter

lifecycleScope.launch {
    pagingData.collectLatest { data ->
        adapter.submitData(data)
    }
}
