Android Studio 的gradle中新增如下依賴，SwipeRefreshLayout在 support V4 包下,RecyclerView在V7包下，由於V7包內包涵了V4，所以就不需要新增V4的依賴了。

  compile 'com.android.support:appcompat-v7:23.0.0'
  compile 'com.android.support:recyclerview-v7:23.0.0'

實現繼承自RecyclerView.Adapter<>的介面卡， 實現上拉載入功能，在RecyclerView的底部新增一個footer，（根據ViewType的型別判斷是新增Item還是Footer），需要重寫的三個方法:

①onCreateViewHolder()
這個方法主要為每個Item inflater出一個View，但是該方法返回的是一個ViewHolder。該方法把View直接封裝在ViewHolder中，然後我們面向的是ViewHolder這個例項，當然這個ViewHolder需要我們自己去編寫。直接省去了當初的convertView.setTag(holder)和convertView.getTag()這些繁瑣的步驟。

②onBindViewHolder()
這個方法主要用於適配渲染資料到View中。方法提供給你了一個viewHolder，而不是原來的convertView。

③getItemCount()
這個方法就類似於BaseAdapter的getCount方法了，即總共有多少個條目。

public class MyAdapter  extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
    public enum LoadStatus{
        CLICK_LOAD_MORE,//上拉載入更多
        LOADING_MORE//正在載入更多
    }
    private LoadStatus mLoadStatus = LoadStatus.CLICK_LOAD_MORE;//上拉載入的狀態
