XRecyclerView 的简单使用

首先是导入依赖

compile 'com.jcodecraeer:xrecyclerview:1.3.2'compile 'com.youth.banner:banner:1.4.9'compile 'com.github.bumptech.glide:glide:3.7.0'compile files('libs/universal-image-loader-1.9.3.jar')

其次xml的布局

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical">    <com.jcodecraeer.xrecyclerview.XRecyclerView        android:id="@+id/xre_xrv"        android:layout_width="match_parent"        android:layout_height="match_parent">    </com.jcodecraeer.xrecyclerview.XRecyclerView></LinearLayout>

activity.java的内容

import android.os.Bundle;import android.support.annotation.Nullable;import android.support.v4.app.Fragment;import android.support.v7.widget.LinearLayoutManager;import android.support.v7.widget.RecyclerView;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.ImageView;import android.widget.TextView;import android.widget.Toast;import com.bwie.test.utils.API;import com.bwie.test.utils.GlideImaGlideImageLoader;import com.bwie.test.utils.GsonObjectCallback;import com.bwie.test.utils.OkHttp3Utils;import com.jcodecraeer.xrecyclerview.XRecyclerView;import com.nostra13.universalimageloader.core.ImageLoader;import com.youth.banner.Banner;import com.youth.banner.loader.ImageLoaderInterface;import java.io.IOException;import java.util.ArrayList;import java.util.List;import okhttp3.Call;public class Fragment_one extends Fragment{    View view;    private XRecyclerView xr;    private List<String> list = new ArrayList<>();    //获取数据的开始    private int curr;    private XRAdapter adapter;    @Nullable    @Override    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {        view=inflater.inflate(R.layout.fragment_one,null);        //初始化xr        xr = (XRecyclerView) view.findViewById(R.id.xre_xrv);        //加布局管理器        LinearLayoutManager layoutManager = new LinearLayoutManager(getActivity());        layoutManager.setOrientation(LinearLayoutManager.VERTICAL);        xr.setLayoutManager(layoutManager);        xr.setLoadingListener(new XRecyclerView.LoadingListener() {            @Override            public void onRefresh() {                curr = 0;                list.clear();                getData(API.TYPE_HOME, curr);                xr.refreshComplete();            }            @Override            public void onLoadMore() {             /*   curr++;                getData(API.TYPE_HOME,curr);                xr.refreshComplete();*/            }        });        getData(API.TYPE_HOME, 1);        return view;    }    //初始化数据    private void getData(String url, int curr) {        OkHttp3Utils.getInstance().doGet(url, new GsonObjectCallback<HomeBean>() {            @Override            public void onUi(HomeBean homeBean) {                List<HomeBean.SongListBean> song_list = homeBean.getSong_list();                homeBean.getError_code();                XRAdapter mxradapter = new XRAdapter(song_list,getActivity());                xr.setAdapter(mxradapter);            }            @Override            public void onFailed(Call call, IOException e) {            }        });    }}

数据解析 就不写了  然后是适配器的配置

import android.content.Context;import android.support.v7.widget.LinearLayoutManager;import android.support.v7.widget.RecyclerView;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import com.bwie.test.utils.GlideImaGlideImageLoader;import com.youth.banner.Banner;import java.util.ArrayList;import java.util.List;public class XRAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {    List<HomeBean.SongListBean> song_list;    Context mcontext;    ArrayList mlist;    ArrayList<Mynews> list_news;    RecyclelistAdapter adapter;    //枚举类型    private enum Item_Type {        Typeone, Typetwo    }    public XRAdapter(List<HomeBean.SongListBean> song_list, Context mcontext) {        this.song_list = song_list;        this.mcontext = mcontext;    }    @Override    public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {        if (viewType == Item_Type.Typeone.ordinal()) {            View mView = LayoutInflater.from(mcontext).inflate(R.layout.recycle_banner_item, null);            ViewHolderA viewHolder = new ViewHolderA(mView);            return viewHolder;        } else{            View mView = LayoutInflater.from(mcontext).inflate(R.layout.recycle_list_item, null);            ViewHolderB viewHolder = new ViewHolderB(mView);            return viewHolder;        }    }    /**     * 绑定数据：可以直接拿到已经绑定控件的Viewholder对象     *     * @param holder     * @param position     */    @Override    public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {        if (holder instanceof ViewHolderA) {            mlist = new ArrayList();            for (int i = 0; i<song_list.size(); i++){                mlist.add(song_list.get(i).getPic_big());            }            //设置图片加载器            ((ViewHolderA) holder).mbanner.setImageLoader(new GlideImaGlideImageLoader());            ((ViewHolderA) holder).mbanner.setImages(mlist);            ((ViewHolderA) holder).mbanner.start();        } else if (holder instanceof ViewHolderB) {            list_news = new ArrayList<Mynews>();            for (int i = 0; i<song_list.size(); i++){                list_news.add(new Mynews(song_list.get(i).getPic_big(),song_list.get(i).getAlbum_title()));            }            ((ViewHolderB) holder).recyclerViewList.setLayoutManager(new LinearLayoutManager(mcontext));            ((ViewHolderB) holder).recyclerViewList.setAdapter(new RecyclelistAdapter(mcontext,list_news));        }    }    @Override    public int getItemCount() {        return song_list.size();    }    @Override    public int getItemViewType(int position) {        if (position == 0) {            return 0;        } else {            return 1;        }    }    class ViewHolderA extends RecyclerView.ViewHolder {        public Banner mbanner;        public ViewHolderA(View itemView) {            super(itemView);            mbanner = (Banner) itemView.findViewById(R.id.banner);        }    }    class ViewHolderB extends RecyclerView.ViewHolder {        public RecyclerView recyclerViewList;        public ViewHolderB(View itemView) {            super(itemView);            recyclerViewList = (RecyclerView) itemView.findViewById(R.id.recycleList);        }    }}
这里面有两个布局 一个是
recycle_banner_item

<com.youth.banner.Banner    android:id="@+id/banner"    android:layout_width="match_parent"    android:layout_height="200dp"></com.youth.banner.Banner>
另一个是 
recycle_list_item
<android.support.v7.widget.RecyclerView    android:id="@+id/recycleList"    android:layout_width="match_parent"    android:layout_height="wrap_content"></android.support.v7.widget.RecyclerView>
这个RecyclerView 还有一个适配器
import android.content.Context;import android.support.v7.widget.RecyclerView;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.ImageView;import android.widget.TextView;import com.nostra13.universalimageloader.core.ImageLoader;import java.util.ArrayList;public class RecyclelistAdapter extends RecyclerView.Adapter
<RecyclelistAdapter.ViewHolder>{    ArrayList<Mynews> list;    Context context;    public RecyclelistAdapter(Context context, ArrayList<Mynews> list) {        this.context = context;        this.list = list;    }    @Override    public RecyclelistAdapter.ViewHolder onCreateViewHolder
(ViewGroup parent, int viewType) {
        ViewHolder holder = new ViewHolder(LayoutInflater.from(context).inflate(R.layout.item_home, parent, false));        return holder;    }    @Override    public void onBindViewHolder(RecyclelistAdapter.ViewHolder holder, int position) {        holder.tv.setText(list.get(position).getTitle());        String imgURL = list.get(position).getPic_url();        ImageLoader instance = ImageLoader.getInstance();        instance.displayImage(imgURL,holder.img);    }    @Override    public int getItemCount() {        return list.size();    }    class ViewHolder extends RecyclerView.ViewHolder{        ImageView img;        TextView tv;        public ViewHolder(View view) {            super(view);            img = (ImageView) view.findViewById(R.id.img);            tv = (TextView) view.findViewById(R.id.tv);        }    }}
这个里面的布局是
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="wrap_content"    android:layout_marginTop="10dp"    android:orientation="horizontal">    <ImageView        android:id="@+id/img"        android:layout_width="wrap_content"        android:layout_height="wrap_content" />    <TextView        android:id="@+id/tv"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:layout_marginLeft="10dp"/></LinearLayout>

这个就是 XRecyclerView的简单使用， 里面是一个轮播图和一个网络请求数据
