使用方法

build.gradle文件

dependencies {
  compile 'com.wuxiaolong.pullloadmorerecyclerview:library:1.0.4'
}

xml引用

 <com.wuxiaolong.pullloadmorerecyclerview.PullLoadMoreRecyclerView
        android:id="@+id/pullLoadMoreRecyclerView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_margin="10dp" />

设置线性布局

 mPullLoadMoreRecyclerView = (PullLoadMoreRecyclerView) view.findViewById(R.id.pullLoadMoreRecyclerView);
 mPullLoadMoreRecyclerView.setLinearLayout();

设置网格布局

 mPullLoadMoreRecyclerView.setGridLayout(2);//参数为列数

设置交错网格布局，即瀑布流效果

 mPullLoadMoreRecyclerView.setStaggeredGridLayout(2);//参数为列数

绑定适配器

  mRecyclerViewAdapter = new RecyclerViewAdapter();
  mPullLoadMoreRecyclerView.setAdapter(mRecyclerViewAdapter);

public class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerViewAdapter.ViewHolder> {

    public RecyclerViewAdapter() {

    }

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.recycler_view_item, parent, false);
        return new ViewHolder(view);
    }

    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {

    }

    @Override
    public int getItemCount() {
        return 0;
    }

    public class ViewHolder extends RecyclerView.ViewHolder {     

        public ViewHolder(View itemView) {
            super(itemView);

        }
    }
}

调用下拉刷新和加载更多

 mPullLoadMoreRecyclerView.setOnPullLoadMoreListener(new PullLoadMoreRecyclerView.PullLoadMoreListener() {
            @Override
            public void onRefresh() {

            }

            @Override
            public void onLoadMore() {               

            }
        });

刷新结束

mPullLoadMoreRecyclerView.setPullLoadMoreCompleted();

其他方法

不需要下拉刷新

mPullLoadMoreRecyclerView.setPullRefreshEnable(false);

不需要上拉刷新

mPullLoadMoreRecyclerView.setPushRefreshEnable(false);

设置上拉刷新文字

mPullLoadMoreRecyclerView.setFooterViewText("loading");

设置下拉刷新颜色

 mPullLoadMoreRecyclerView.setColorSchemeResources(android.R.color.holo_red_dark,android.R.color.holo_blue_dark);

快速Top

  mPullLoadMoreRecyclerView.scrollToTop();
