XRecyclerview和Recyclerview详解

XRecyclerview和Recyclerview相似,但是XRecyclerview自带下拉刷新和上拉加载更多的功能,除了引用不一样,其他的都一样,下面写详细代码:

注意!!!!两种不能一同使用

首先导入依赖

XRecyclerview的依赖:

compile 'com.jcodecraeer:xrecyclerview:1.3.2'

Recyclerview的依赖:

compile 'com.android.support:recyclerview-v7:26.0.0-alpha1'

首先在布局当中进行引用:

然后在Activity中初始化:

一共有三种方式,对应三种模式

1.线性流:

rv.setLayoutManager(new LinearLayoutManager(this));

2.网格

rv.setLayoutManager(new GridLayoutManager(this,3));

3.瀑布流

rv.setLayoutManager(new StaggeredGridLayoutManager(3, StaggeredGridLayoutManager.VERTICAL));

然后写适配器,带点击事件的适配器,(点击事件使用的是接口回调)

package com.bwei.manshopping.Adapters;import android.content.Context;import android.net.Uri;import android.support.v7.widget.RecyclerView;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.LinearLayout;import android.widget.TextView;import com.bwei.manshopping.Bean.GoodListsBean;import com.bwei.manshopping.R;import com.facebook.drawee.view.SimpleDraweeView;import java.util.List;/** * Created by 31962 on 2017/10/20. */public class GoodsListAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {    private List<GoodListsBean.DatasBean.GoodsListBean>  list;    private Context context;    private OnIClickListener oniclicklistener;    public GoodsListAdapter(List<GoodListsBean.DatasBean.GoodsListBean> list, Context context) {        this.list = list;        this.context = context;    }    public void setOnIclicklistener(OnIClickListener oniclicklistener){        this.oniclicklistener = oniclicklistener;    }    public interface OnIClickListener{        public void onItemclick(GoodListsBean.DatasBean.GoodsListBean bean);    }    @Override    public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {        View view = LayoutInflater.from(context).inflate(R.layout.goodslistitem, parent, false);        MyViewHolder myViewHolder = new MyViewHolder(view);        return myViewHolder;    }    @Override    public void onBindViewHolder(RecyclerView.ViewHolder holder, final int position) {        MyViewHolder myholder = (MyViewHolder) holder;        Uri imageuri = Uri.parse(list.get(position).getGoods_image_url());        myholder.sdv.setImageURI(imageuri);        myholder.name.setText(list.get(position).getGoods_name());        myholder.price.setText(list.get(position).getGoods_price());        myholder.sale.setText("销量"+list.get(position).getGoods_salenum());        myholder.ll_goodlist.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                if(oniclicklistener!=null){                    oniclicklistener.onItemclick(list.get(position));                }            }        });    }    @Override    public int getItemCount() {        return list.size();    }    public class MyViewHolder extends RecyclerView.ViewHolder {        private final SimpleDraweeView sdv;        private final TextView name;        private final TextView price;        private final TextView sale;        private final LinearLayout ll_goodlist;        public MyViewHolder(View itemView) {            super(itemView);            sdv = itemView.findViewById(R.id.Sdv);            name = itemView.findViewById(R.id.tv_name_GoodsActivity);            price = itemView.findViewById(R.id.tv_price_GoodsActivity);            sale = itemView.findViewById(R.id.tv_sale_GoodsActivity);            ll_goodlist = itemView.findViewById(R.id.ll_goodlist);        }    }}

另外,在Activity中,XRecycler中可以设置加载的监听器:

xRv.setLoadingListener(new XRecyclerView.LoadingListener() {    @Override    public void onRefresh() {        myAdapter.refresh();        getInfo();        xRv.refreshComplete();    }    @Override    public void onLoadMore() {        Toast.makeText(UserActivity.this,"哈哈",Toast.LENGTH_SHORT).show();        xRv.loadMoreComplete();        xRv.setLoadingMoreEnabled(true);        xRv.setLoadingMoreProgressStyle(ProgressStyle.SquareSpin);        String url = "http://tingapi.ting.baidu.com/v1/restserver/ting?method=baidu.ting.billboard.billList&type=1&size=10&offset=0";        HttpUtil.getInstance().doGet(url, MusicBean.class, new OnNetListener() {            @Override            public void onError(IOException e) {            }            @Override            public void onSuccess(MusicBean musicBean) throws IOException {                List<MusicBean.SongListBean> song_list2 = musicBean.getSong_list();                myAdapter.loadmore(song_list2);            }        });    }});

有的时候有分页加载的需求,分页加载的适配器:

public class MyAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
    private Context context;
    private List<ItemBean> list;
    private OnItemListener onItemListener;
    private static int TYPE1 = 0;
    private static int TYPE2 = 1;

    public interface OnItemListener {
        public void onItemClick(ItemBean itemBean, int position);

        public void onItemLongClick(ItemBean itemBean, int position);
    }

    public void setOnItemListener(OnItemListener onItemListener) {
        this.onItemListener = onItemListener;
    }

    public MyAdapter(Context context, List<ItemBean> list) {
        this.context = context;
        this.list = list;
    }

    @Override
    public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        //加载写好的item布局
        RecyclerView.ViewHolder viewHolder = null;
        if (viewType == TYPE1) {
            View view1 = LayoutInflater.from(context).inflate(R.layout.item1, parent, false);
            viewHolder = new Type1Viewholder(view1);
        } else {
            View view2 = LayoutInflater.from(context).inflate(R.layout.item2, parent, false);
            viewHolder = new Type2Viewholder(view2);
        }


        return viewHolder;
    }

    @Override
    public int getItemViewType(int position) {
        return position % 2 == 0 ? TYPE1 : TYPE2;
    }

    @Override
    public void onBindViewHolder(RecyclerView.ViewHolder holder, final int position) {
        //给item布局里的组件设置值
        if (holder instanceof Type1Viewholder) {
            final ItemBean itemBean = list.get(position);
            Type1Viewholder type1Viewholder = (Type1Viewholder) holder;
            type1Viewholder.tvName.setText(itemBean.getName());
            type1Viewholder.tvAge.setText(itemBean.getAge());

            type1Viewholder.ll.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    if (onItemListener != null) {
                        onItemListener.onItemClick(itemBean, position);
                    }
                }
            });
            type1Viewholder.ll.setOnLongClickListener(new View.OnLongClickListener() {
                @Override
                public boolean onLongClick(View view) {
                    if (onItemListener != null) {
                        onItemListener.onItemLongClick(itemBean, position);
                    }
                    return true;
                }
            });
        } else {
            Type2Viewholder type2Viewholder = (Type2Viewholder) holder;
        }
    }

    @Override
    public int getItemCount() {
        return list.size();
    }

    private class Type1Viewholder extends RecyclerView.ViewHolder {
        //类似listview的adapter的viewholder
        private TextView tvName;
        private TextView tvAge;
        private LinearLayout ll;

        public Type1Viewholder(View itemView) {
            super(itemView);
            tvName = itemView.findViewById(R.id.tv_name);
            tvAge = itemView.findViewById(R.id.tv_age);
            ll = itemView.findViewById(R.id.ll);
        }
    }

    private class Type2Viewholder extends RecyclerView.ViewHolder {

        public Type2Viewholder(View itemView) {
            super(itemView);
        }
    }


    public void refresh(List<ItemBean> l) {
        list.clear();
        list.addAll(l);
        notifyDataSetChanged();
    }

    public void addItem(ItemBean itemBean) {
        list.add(0, itemBean);
        notifyItemInserted(0);
    }
