LoadStateAdapter()
```
- Method Detail
  - getLoadState
```
 final LoadState getLoadState()
```
    Changing this property will immediately notify the Adapter to change the item it's presenting. LoadState.None is the initial state.
    要在适配器中显示的 LoadState。更改此属性将立即通知适配器更改 item 的样式。 LoadState.None 为初始状态。
  - setLoadState
```
 final Unit setLoadState(LoadState loadState)
```
  - getIsLoading
```
 final Boolean getIsLoading()
```
  - getRecyclerView
```
 final RecyclerView getRecyclerView()
```
  - setRecyclerView
```
 final Unit setRecyclerView(RecyclerView recyclerView)
```
  - onCreateViewHolder
```
 final VH onCreateViewHolder(ViewGroup parent, Integer viewType)
```
  - onCreateViewHolder
```
 abstract VH onCreateViewHolder(ViewGroup parent, LoadState loadState)
```
    Called to create a ViewHolder for the given LoadState.
    调用此方法，为 LoadState 创建 ViewHolder。
    
    Parameters:
    
    parent - The ViewGroup into which the new View will be added after it is bound to an adapter position.
    
    loadState - The LoadState to be initially presented by the new ViewHolder.
  - onBindViewHolder
```
 final Unit onBindViewHolder(VH holder, Integer position)
```
  - onBindViewHolder
```
 final Unit onBindViewHolder(VH holder, Integer position, List<Object> payloads)
```
  - onBindViewHolder
```
 abstract Unit onBindViewHolder(VH holder, LoadState loadState)
```
    Called to bind the passed LoadState to the ViewHolder.
    调用此方法，将 LoadState 状态绑定至 ViewHolder
    
    Parameters:
    
    loadState - LoadState to display.
  - getItemViewType
```
 final Integer getItemViewType(Integer position)
```
  - getItemCount
```
 final Integer getItemCount()
```
  - onAttachedToRecyclerView
```
@CallSuper() Unit onAttachedToRecyclerView(RecyclerView recyclerView)
```
  - onDetachedFromRecyclerView
```
@CallSuper() Unit onDetachedFromRecyclerView(RecyclerView recyclerView)
```
  - getStateViewType
```
 Integer getStateViewType(LoadState loadState)
```
    Override this method to use different view types per LoadState. 重写此方法以对每个 LoadState 使用不同的 View 类型。
    By default, this LoadStateAdapter only uses a single view type.
  - displayLoadStateAsItem
```
 Boolean displayLoadStateAsItem(LoadState loadState)
```
    Returns true if the LoadState should be displayed as a list item when active.
    By default, LoadState.Loading and LoadState.Error present as list items, others do not.
    如果 LoadState 在激活时需要显示item，则返回 true。默认情况下，LoadState.Loading 和 LoadState.Error 将会显示，其他则不显示。
  - addLoadStateListener
```
 final Unit addLoadStateListener(LoadStateAdapter.LoadStateListener listener)
```
  - removeLoadStateListener
```
 final Unit removeLoadStateListener(LoadStateAdapter.LoadStateListener listener)
```
