本文介绍了一款游戏界面的设计与实现过程，详细讲解了如何使用Java和相关框架来构建游戏列表视图，包括数据加载、适配器设计、图片加载策略及数据解析等方面。

Game界面和App界面一样

GameFragment.java

package com.ldw.market.fragment;

import java.util.List;

import com.ldw.market.R;
import com.ldw.market.Adapter.DefaultAdapter;
import com.ldw.market.domain.AppInfo;
import com.ldw.market.fragment.AppFragment.AppAdapter;
import com.ldw.market.fragment.AppFragment.ViewHolder;
import com.ldw.market.fragment.BaseFragment.LoadResult;
import com.ldw.market.holder.BaseHolder;
import com.ldw.market.http.HttpHelper;
import com.ldw.market.protocol.AppProtocol;
import com.ldw.market.protocol.GameProtocol;
import com.ldw.market.utils.UiUtils;
import com.ldw.market.view.BaseListView;
import com.lidroid.xutils.bitmap.PauseOnScrollListener;

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.text.format.Formatter;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.RatingBar;
import android.widget.TextView;

public class GameFragment extends BaseFragment {

	List<AppInfo> datas;
	//加载成功，显示ListView
	@Override
	public View createSuccessView() {
		BaseListView  listView=new BaseListView(UiUtils.getContext());
		listView.setAdapter(new GameAdapter(datas));
		// 第二个参数 慢慢滑动的时候是否加载图片 false  加载   true 不加载
		//  第三个参数  飞速滑动的时候是否加载图片  true 不加载 
		listView.setOnScrollListener(new PauseOnScrollListener(bitmapUtils, false, true));
		bitmapUtils.configDefaultLoadingImage(R.drawable.ic_default);  // 设置如果图片加载中显示的图片
        bitmapUtils.configDefaultLoadFailedImage(R.drawable.ic_default);// 加载失败显示的图片
		return listView;
	}
	
	public class GameAdapter extends DefaultAdapter<AppInfo>{

		public GameAdapter(List<AppInfo> datas) {
			super(datas);
			// TODO Auto-generated constructor stub
		}

		@Override
		protected BaseHolder<AppInfo> getHolder() {
			return new ViewHolder();
		}
		
	}
	
	static class ViewHolder extends BaseHolder<AppInfo>{
		ImageView item_icon;
		TextView item_title,item_size,item_bottom;
		RatingBar item_rating;

		
		//更新界面
		@Override
		public void refreshView(AppInfo data){
			this.item_title.setText(data.getName());// 设置应用程序的名字
			String size = Formatter.formatFileSize(UiUtils.getContext(), data.getSize());
			this.item_size.setText(size);
			this.item_bottom.setText(data.getDes());
			float stars = data.getStars();
			this.item_rating.setRating(stars); // 设置ratingBar的值
			String iconUrl = data.getIconUrl(); //这个地址不全，需要加上apache地址"iconUrl": "app/com.youyuan.yyhl/icon.jpg",
			//http://127.0.0.1:8090/image?name=app/com.youyuan.yyhl/icon.jpg
			
			
			//第一个参数是显示图片的控件，第二个参数是显示图片的url
			bitmapUtils.display(this.item_icon, HttpHelper.URL+"image?name="+iconUrl);
			// 显示图片的控件
			//bitmapUtils.display(holder.item_icon, HttpHelper.URL+"image?name="+iconUrl);
		}

		@Override
		public View initView() {
			View contentView = View.inflate(UiUtils.getContext(), R.layout.item_app, null);
			this.item_icon = (ImageView) contentView.findViewById(R.id.item_icon);
			this.item_title = (TextView) contentView.findViewById(R.id.item_title);
			this.item_size = (TextView) contentView.findViewById(R.id.item_size);
			this.item_bottom = (TextView) contentView.findViewById(R.id.item_bottom);
			this.item_rating = (RatingBar) contentView.findViewById(R.id.item_rating);
			return contentView;
		}

	}

	/*
	 * 请求服务器获取服务器的数据(non-Javadoc)
	 * @see com.ldw.market.fragment.BaseFragment#load()
	 */
	@Override
	protected LoadResult load() {
		GameProtocol protocol = new GameProtocol();
		datas = protocol.load(0);
		return checkData(datas);
	}

}

GameProtocal.java

package com.ldw.market.protocol;

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

import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;

import com.ldw.market.domain.AppInfo;

public class GameProtocol extends BaseProtocol<List<AppInfo>>{

	@Override
	public List<AppInfo> parseJson(String json) {
		List<AppInfo> appInfos = new ArrayList<AppInfo>();
		//获取到中括号的内容
		try {
			JSONArray jsonArray = new JSONArray(json);
			for(int i = 0; i< jsonArray.length();i ++){
				//获取到array里面的Object
				JSONObject jsonObj = jsonArray.getJSONObject(i);
				//解析Object里面的条目
				long id = jsonObj.getLong("id");
				String name = jsonObj.getString("name");
				String packageName = jsonObj.getString("packageName");

				float stars = Float.parseFloat(jsonObj.getString("stars"));
				long size = jsonObj.getLong("size");
				String downloadUrl = jsonObj.getString("downloadUrl");
				String des = jsonObj.getString("des");
				
				//构造函数，创建一个appInfo
				AppInfo appInfo = new AppInfo(id, name, packageName, iconUrl,
						stars, size, downloadUrl, des);
				//往集合中添加对象
				appInfos.add(appInfo);
			}
			return appInfos;
		} catch (JSONException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
			return null;
		}
		
	}

	@Override
	public String getKey() {
		// TODO Auto-generated method stub
		return "game";
	}
