14.不同条目的listview

分类界面

整个项目的逻辑就是这样的

CategoryInfo 
  1. public class CategoryInfo {
  2. 	private String title;
  3. 	private String url1;
  4. 	private String url2;
  5. 	private String url3;
  6. 	private String name1;
  7. 	private String name2;
  8. 	private String name3;
  9. 	
  10. 	private  boolean  isTitle;// 是否是标题，指的是游戏，应用这些标题，下面的字段也是也是叫title，所以也这样写
  11. 	
  12. 	
  13. 	public boolean isTitle() {
  14. 		return isTitle;
  15. 	}
  16. 	public void setIsTitle(boolean isTitle) {
  17. 		this.isTitle = isTitle;
  18. 	}
CategoryProtocol
  1. public class CategoryProtocol extends BaseProtocol<List<CategoryInfo>> {
  3. 	@Override
  4. 	public List<CategoryInfo> paserJson(String json) {
  5. 		List<CategoryInfo> categoryInfos=new ArrayList<CategoryInfo>();
  6. 		try {
  7. 			JSONArray array=new JSONArray(json);
  8. 			for(int i=0;i<array.length();i++){
  9. 				JSONObject jsonObject = array.getJSONObject(i);
  10. 				String title=jsonObject.getString("title");
  11. 				CategoryInfo categoryInfo=new CategoryInfo();
  12. 				categoryInfo.setTitle(title);
  13. 				categoryInfo.setIsTitle(true);
  14. 				categoryInfos.add(categoryInfo);
  15. 				
  16. 				JSONArray jsonArray = jsonObject.getJSONArray("infos");
  17. 				for(int j=0;j<jsonArray.length();j++){
  18. 					JSONObject jsonObject2 = jsonArray.getJSONObject(j);
  19. 					String url1=jsonObject2.getString("url1");
  20. 					String url2=jsonObject2.getString("url2");
  21. 					String url3=jsonObject2.getString("url3");
  22. 					String name1=jsonObject2.getString("name1");
  23. 					String name2=jsonObject2.getString("name2");
  24. 					String name3=jsonObject2.getString("name3");
  25. 					CategoryInfo categoryInfo2=new CategoryInfo(title, url1, url2, url3, name1, name2, name3,false);
  26. 					categoryInfos.add(categoryInfo2);
  27. 				}
  28. 				
  29. 			}
  30. 			return categoryInfos;
  31. 			
  32. 		} catch (JSONException e) {
  33. 			e.printStackTrace();
  34. 			return null;
  35. 		}
  36. 	
  37. 	}
  39. 	@Override
  40. 	public String getKey() {
  41. 		return "category";
  42. 	}
  44. }
布局（三个这）
  1. <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  2.     android:layout_width="match_parent"
  3.     android:layout_height="match_parent"
  4.     android:clickable="false"
  5.     android:orientation="horizontal"
  6.     android:paddingLeft="5dp"
  7.     android:paddingRight="5dp" >
  9.     <RelativeLayout
  10.         android:id="@+id/rl_1"
  11.         android:layout_width="0dip"

  24.             android:scaleType="fitXY"
  25.             android:src="@drawable/ic_default" />

CategoryContentHolder

  21. 	@Override

  14. 	public void refreshView(CategoryInfo data) {
  15. 		tv.setText(data.getTitle());
  16. 	}
  18. }
CategoryFragment （ 注意CategoryAdapter）
  1. public class CategoryFragment extends BaseFragment {
  2. 	private List<CategoryInfo> datas;
  3. 	public static int ITEM_TITLE =2;
  5. 	// 创建成功的界面

修改DefaultAdapter
  1. 	public View getView(int position, View convertView, ViewGroup parent) {
  2. 		BaseHolder holder = null;
  4. 		switch (getItemViewType(position)) {  // 判断当前条目时什么类型
  5. 		case MORE_ITEM:

  14. 				holder = getHolder();
  15. 			} else {
  16. 				System.out.println("aaa");
  17. 				holder = (BaseHolder) convertView.getTag();
  18. 			}
  19. 			if (position < datas.size()) {
  20. 				holder.setData(datas.get(position));
  21. 			}
  22. 			break;
  23. 		}
  24. 		return holder.getContentView();  //  如果当前Holder 恰好是MoreHolder  证明MoreHOlder已经显示
  25. 	}
  26. 	private MoreHolder holder;
  27. 	private BaseHolder getMoreHolder() {
  28. 		if(holder!=null){
  29. 			return holder;
  30. 		}else{
  31. 			holder=new MoreHolder(this,hasMore());
  32. 			return holder;
  33. 		}
  34. 	}
  35. 	/**
  36. 	 * 是否有额外的数据
  37. 	 * @return
  38. 	 */
  39. 	protected boolean hasMore() {
  40. 		return true;
