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<Bean.SongListBean> 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<Bean.SongListBean> list = new ArrayList<>();
private ViewHolder1 holder1;
private ViewHolder2 holder2;

public MyAdapter(Context context, List<Bean.SongListBean> 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
