RecyclerView的使用

一、添加依赖：

二、布局：

<android.support.v7.widget.RecyclerView    android:id="@+id/recycler_view"    android:layout_width="match_parent"    android:layout_height="match_parent"    ></android.support.v7.widget.RecyclerView>

三、activity代码：

recyclerView = (RecyclerView) findViewById(R.id.recycler_view);

recyclerView.setLayoutManager(new GridLayoutManager(SelectActivity.this,2));GvAdapter adapter=new GvAdapter(data,SelectActivity.this);recyclerView.setAdapter(adapter);

四、适配器：

package com.example.day09_kuangjia_login.adapter;import android.content.Context;import android.support.v7.widget.RecyclerView;import android.util.Log;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import com.example.day09_kuangjia_login.R;import com.example.day09_kuangjia_login.holder.MyHolder;import com.example.day09_kuangjia_login.model.bean.SelBean;import com.example.day09_kuangjia_login.utils.ImageUtil;import com.nostra13.universalimageloader.core.ImageLoader;import java.util.ArrayList;import java.util.List;/** * Created by DESKTOP on 2017/12/9. */public class GvAdapter extends RecyclerView.Adapter<MyHolder>{    List<SelBean.DataBean> data;    Context con;    List<String> imgs=new ArrayList<>();    public GvAdapter(List<SelBean.DataBean> data, Context con) {        this.data = data;        this.con = con;    }    @Override    public MyHolder onCreateViewHolder(ViewGroup parent, int viewType) {        View view = LayoutInflater.from(con).inflate(R.layout.gv_child, parent, false);        MyHolder holder=new MyHolder(view);        return holder;    }    @Override    public void onBindViewHolder(MyHolder holder, int position) {        for (int i = 0; i< data.size(); i++){            String[] images = data.get(i).getImages().split("\\|");            Log.d("iiiii",images.toString());            for (int j=0;j<images.length;j++){                imgs.add(images[j]);            }        }        holder.price.setText("折扣价"+data.get(position).getPrice());        holder.title.setText(data.get(position).getTitle());        ImageLoader.getInstance().displayImage(imgs.get(position),holder.image, ImageUtil.getoption());    }    @Override    public int getItemCount() {        return data.size();    }}

五、holder：

package com.example.day09_kuangjia_login.holder;import android.support.v7.widget.RecyclerView;import android.view.View;import android.widget.ImageView;import android.widget.TextView;import com.example.day09_kuangjia_login.R;/** * Created by DESKTOP on 2017/12/9. */public class GvHolder extends RecyclerView.ViewHolder{    public final ImageView image;    public final TextView title;    public final TextView price;    public GvHolder(View itemView) {        super(itemView);        image = (ImageView) itemView.findViewById(R.id.img);        title = itemView.findViewById(R.id.title);        price = (TextView) itemView.findViewById(R.id.price);    }}
、、、这是现实表格样式的条目
、、、想要列表样式就把activity中的
recyclerView.setLayoutManager(new GridLayoutManager(SelectActivity.this,2));
代码和布局修改和替换
recyclerView.setLayoutManager(new LinearLayoutManager(SelectActivity.this,LinearLayoutManager.VERTICAL,false));
