SSS___listview多条目加载、使用okhttp请求网络数据，Glide加载图片

今天无聊的时候在做list view多条目加载，整了老半天再出来，所以今天把他总结一下发出来，希望给那些初学者一些便利，话不多说，先来看一下效果

本人只加载了两种条目，其实可以记载很多，但是由于本人懒所以就加载了两条，来看一下代码吧 

 

package com.example.week3demo;
import android.os.Bundle;
import android.os.Handler;
import android.support.v7.app.AppCompatActivity;
import android.util.Log;
import android.widget.ListView;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
import okhttp3.Call;
import okhttp3.Callback;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.Response;
public class Main3Activity extends AppCompatActivity {
    List list=new ArrayList<>();
    private Request request;
    Bean bean;
    String url="http://tingapi.ting.baidu.com/v1/restserver/ting?method=baidu.ting.billboard.billList&type=1&size=10&offset=0";
    private Handler handler = new Handler();
        ListView listview;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main3);
        listview= (ListView) findViewById(R.id.listview);
        initData();
    }
    private void initData() {
        OkHttpClient client = new OkHttpClient();
        request = new Request.Builder().addHeader("User-Agent", "").url(url).build();
        Call call = client.newCall(request);
        call.enqueue(new Callback() {
            @Override
            public void onFailure(Call call, IOException e)
            {
                Log.d("onFailure", "请求失败");
            }
            @Override
            public void onResponse(Call call, Response response) throws IOException {
                if (response.body() != null && response.isSuccessful()) {
                    String result = response.body().string();
                    bean=Bean.objectFromData(result);
                    list=bean.song_list;
                    handler.post(new Runnable() {
                        @Override
                        public void run() {
                            listview.setAdapter(new MyAdapter(Main3Activity.this, list));
                        }
                    });
                } else {
                    Log.d("onFailure", "请求失败");
                }
            }
        });
    }
}

主方法里就这么点，

 

再来看一下adapter里面的吧：

 

package com.example.week3demo;

import android.content.Context;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.TextView;

import com.bumptech.glide.Glide;

import java.util.ArrayList;
import java.util.List;



public class MyAdapter extends BaseAdapter {
    Context context;
    List list = new ArrayList<>();
    private ViewHolder1 holder1;
    private ViewHolder2 holder2;

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

    private final int TYPE_1 = 0;// 类型1
    private final int TYPE_2 = 1; //类型2

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

    @Override
    public Object getItem(int position) {
        return list.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public int getItemViewType(int position) {
        if (position % 2 == 0) {
            return TYPE_1;
        } else {
            return TYPE_2;
        }
    }

    @Override
    public int getViewTypeCount() {
        return 2;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        holder1 = null;
        holder2 = null;
        int type = getItemViewType(position);
        if (convertView == null) {
            switch (type) {
                case TYPE_1:
                    holder1 = new ViewHolder1();
                    convertView = View.inflate(context, R.layout.main3_item1, null);
                   holder1.image1 = (ImageView) convertView.findViewById(R.id.image1);
                   holder1.biaoti1 = (TextView)convertView .findViewById(R.id.biaoti1);
                    holder1.xiaobiaoti1 = (TextView)convertView .findViewById(R.id.xiaobiaoti1);
                    holder1.shijian1 = (TextView)convertView .findViewById(R.id.shijian1);

                    convertView.setTag(holder1);

                    break;
                case TYPE_2:
                    holder2=new ViewHolder2();
                    convertView = View.inflate(context, R.layout.main3_item2, null);
                    holder2.biaoti2 = (TextView)convertView .findViewById(R.id.biaoti2);
                    holder2.shijian2 = (TextView)convertView .findViewById(R.id.shijian2);
                    holder2.xiaobiaoti2 = (TextView)convertView .findViewById(R.id.xiaobiaoti2);
                    convertView.setTag(holder2);
                    break;
                default:
                    break;

            }
        }

        switch (type) {
            case TYPE_1:
                holder1 = (ViewHolder1) convertView.getTag();
                Glide.with(context).load(list.get(position).pic_big).into(holder1.image1);
                holder1.biaoti1.setText(list.get(position).si_proxycompany);
                holder1.xiaobiaoti1.setText(list.get(position).album_title);
                holder1.shijian1.setText("时间" + list.get(position).publishtime);
                break;
            case TYPE_2:
                holder2 = (ViewHolder2) convertView.getTag();
                holder2.biaoti2.setText(list.get(position).si_proxycompany);
                holder2.xiaobiaoti2.setText(list.get(position).album_title);
                holder2.shijian2.setText("时间" + list.get(position).publishtime);
                break;
            default:
                break;
        }
        return convertView;
    }


    public static class ViewHolder1 {

        public ImageView image1;
        public TextView biaoti1;
        public TextView xiaobiaoti1;
        public TextView shijian1;

    }

    class ViewHolder2 {
        public TextView biaoti2;
        public TextView xiaobiaoti2;
        public TextView shijian2;


    }
}

最后把依赖也发出来吧
