RecyclerView实现下拉刷新与自动加载控件封装

前端时间自己整合了一个listview实现的下拉刷新上拉自动加载的demo,有需要的看这里listview实现下拉刷新上拉自动加载，由于新版本APP采用到RecyclerView,发现找不到一个好的简单的效果，于是抽几天时间，结合大牛们的文章，整合出一个比较简洁的RecyclerView实现下拉刷新与自动加载控件

一.废话不多少看效果（本人比较笨，不会制作动态图，哈哈哈）：

1.第一进入页面的效果图

2.数据为空的效果图

3.下拉刷新的效果

4.加载更多时效果

5.没有更多数据时的效果

二.代码放送

自定义一个控件MyRecycleView 继承linearlayout,将RecycleView和SwipeRefreshLayout添加进去即可实现下拉刷新效果，对于自动加载布局，需要添加footview,可惜RecycleView不是自带footview,那么就要自己通过itemType的不同来实现footview,这里需要通过adapter实现，那么就需要自己定义一个LoadMoreWrapper,用于接收设置的adapter进行装饰
1.自定义一个通用的adapter

CommonAdapter.java

public abstract class CommonAdapter<T> extends RecyclerView.Adapter<ViewHolder>{    protected Context mContext;    protected int mLayoutId;    protected List<T> mDatas;    protected LayoutInflater mInflater;    protected OnItemClickListener mOnItemClickListener;    public CommonAdapter(Context context, int layoutId, List<T> datas)    {        mContext = context;        mInflater = LayoutInflater.from(context);        mLayoutId = layoutId;        mDatas = datas;    }    protected boolean isEnabled(int viewType) {        return true;    }    @Override    public ViewHolder onCreateViewHolder(final ViewGroup parent, int viewType)    {        ViewHolder viewHolder = ViewHolder.createViewHolder(mContext, parent, mLayoutId);        setListener(parent, viewHolder, viewType);        return viewHolder;    }    protected void setListener(final ViewGroup parent, final ViewHolder viewHolder, int viewType) {        if (!isEnabled(viewType)) return;        viewHolder.getConvertView().setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                if (mOnItemClickListener != null) {                    int position = viewHolder.getAdapterPosition();                    mOnItemClickListener.onItemClick(v, viewHolder , position);                }            }        });        viewHolder.getConvertView().setOnLongClickListener(new View.OnLongClickListener() {            @Override            public boolean onLongClick(View v) {                if (mOnItemClickListener != null) {                    int position = viewHolder.getAdapterPosition();                    return mOnItemClickListener.onItemLongClick(v, viewHolder, position);                }                return false;            }        });    }    @Override    public void onBindViewHolder(ViewHolder holder, int position)    {        convert(holder, mDatas.get(position),position);    }    protected abstract void convert(ViewHolder holder, T t,int position);    @Override    public int getItemCount()    {        return mDatas.size();    }    public void setOnItemClickListener(OnItemClickListener onItemClickListener) {        this.mOnItemClickListener = onItemClickListener;    }    public interface OnItemClickListener {        void onItemClick(View view, RecyclerView.ViewHolder holder, int position);        boolean onItemLongClick(View view, RecyclerView.ViewHolder holder, int position);    }}
2.定义一个LoadMoreWrapper

LoadMoreWrapper.java
public class LoadMoreWrapper<T> extends RecyclerView.Adapter<RecyclerView.ViewHolder>{    public static final int ITEM_TYPE_LOAD_MORE = Integer.MAX_VALUE - 2;    private RecyclerView.Adapter mInnerAdapter;    private View mLoadMoreView;    private int mLoadMoreLayoutId;    private RelativeLayout mFooterView;    private View mNodataView;    public LoadMoreWrapper(RecyclerView.Adapter adapter)    {        mInnerAdapter = adapter;    }    private boolean hasLoadMore()    {        return mLoadMoreView != null || mLoadMoreLayoutId != 0;    }    private boolean isShowLoadMore(int position)    {        return hasLoadMore() && (position >= mInnerAdapter.getItemCount());    }    @Override    public int getItemViewType(int position)    {        if (isShowLoadMore(position))        {            return ITEM_TYPE_LOAD_MORE;        }        return mInnerAdapter.getItemViewType(position);    }    @Override    public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType)    {        if (viewType == ITEM_TYPE_LOAD_MORE)        {            ViewHolder holder;            if (mLoadMoreView != null)            {                mFooterView = (RelativeLayout) LayoutInflater.from(parent.getContext()).inflate(R.layout.myrecycle_footview, parent,                        false);                mNodataView=LayoutInflater.from(parent.getContext()).inflate(R.layout.myrecycle_nodata_view, parent,                        false);                mFooterView.addView(mLoadMoreView);                mFooterView.addView(mNodataView);                mNodataView.setVisibility(View.GONE);                holder = ViewHolder.createViewHolder(parent.getContext(),mFooterView);            } else            {                mFooterView = (RelativeLayout) LayoutInflater.from(parent.getContext()).inflate(R.layout.myrecycle_footview, parent,                        false);                mNodataView=LayoutInflater.from(parent.getContext()).inflate(R.layout.myrecycle_nodata_view, parent,                        false);                mLoadMoreView=LayoutInflater.from(parent.getContext()).inflate(R.layout.default_loading, parent,                        false);                mFooterView.addView(mLoadMoreView);                mFooterView.addView(mNodataView);                mNodataView.setVisibility(View.GONE);                holder = ViewHolder.createViewHolder(parent.getContext(),mFooterView);            }            return holder;        }        return mInnerAdapter.onCreateViewHolder(parent, viewType);    }    @Override    public void onBindViewHolder(RecyclerView.ViewHolder holder, int position)    {        if (isShowLoadMore(position))        {            if (mOnLoadMoreListener != null)            {                mOnLoadMoreListener.onLoadMoreRequested();            }            return;        }        mInnerAdapter.onBindViewHolder(holder, position);    }    @Override    public void onAttachedToRecyclerView(RecyclerView recyclerView)    {        WrapperUtils.onAttachedToRecyclerView(mInnerAdapter, recyclerView, new WrapperUtils.SpanSizeCallback()        {            @Override            public int getSpanSize(GridLayoutManager layoutManager, GridLayoutManager.SpanSizeLookup oldLookup, int position)            {                if (isShowLoadMore(position))                {                    return layoutManager.getSpanCount();                }                if (oldLookup != null)                {                    return oldLookup.getSpanSize(position);                }                return 1;            }        });    }    @Override    public void onViewAttachedToWindow(RecyclerView.ViewHolder holder)    {        mInnerAdapter.onViewAttachedToWindow(holder);        if (isShowLoadMore(holder.getLayoutPosition()))        {            setFullSpan(holder);        }    }    private void setFullSpan(RecyclerView.ViewHolder holder)    {        ViewGroup.LayoutParams lp = holder.itemView.getLayoutParams();        if (lp != null                && lp instanceof StaggeredGridLayoutManager.LayoutParams)        {            StaggeredGridLayoutManager.LayoutParams p = (StaggeredGridLayoutManager.LayoutParams) lp;            p.setFullSpan(true);        }    }    @Override    public int getItemCount()    {        return mInnerAdapter.getItemCount() + (hasLoadMore() ? 1 : 0);    }    public interface OnLoadMoreListener    {        void onLoadMoreRequested();    }    private OnLoadMoreListener mOnLoadMoreListener;    public void setFootCanLoad(boolean footCanload) {        if(hasLoadMore()) {            if (footCanload) {//如果可以加载更多布局                mNodataView.setVisibility(View.GONE);            } else {                mNodataView.setVisibility(View.VISIBLE);            }        }    }    public LoadMoreWrapper setOnLoadMoreListener(OnLoadMoreListener loadMoreListener)    {        if (loadMoreListener != null)        {            mOnLoadMoreListener = loadMoreListener;        }        return this;    }    public LoadMoreWrapper setLoadMoreView(View loadMoreView)    {        mLoadMoreView = loadMoreView;        return this;    }    public LoadMoreWrapper setLoadMoreView(int layoutId)    {        mLoadMoreLayoutId = layoutId;        return this;    }
3.对recycleview 的封装
