14.不同条目的listview

分类界面

整个项目的逻辑就是这样的

CategoryInfo 

public class CategoryInfo {
	private String title;
	private String url1;
	private String url2;
	private String url3;
	private String name1;
	private String name2;
	private String name3;
	
	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
	
	
	public boolean isTitle() {
		return isTitle;
	}
	public void setIsTitle(boolean isTitle) {
		this.isTitle = isTitle;
	}

CategoryProtocol

public class CategoryProtocol extends BaseProtocol<List<CategoryInfo>> {
	@Override
	public List<CategoryInfo> paserJson(String json) {
		List<CategoryInfo> categoryInfos=new ArrayList<CategoryInfo>();
		try {
			JSONArray array=new JSONArray(json);
			for(int i=0;i<array.length();i++){
				JSONObject jsonObject = array.getJSONObject(i);
				String title=jsonObject.getString("title");
				CategoryInfo categoryInfo=new CategoryInfo();
				categoryInfo.setTitle(title);
				categoryInfo.setIsTitle(true);
				categoryInfos.add(categoryInfo);
				
				JSONArray jsonArray = jsonObject.getJSONArray("infos");
				for(int j=0;j<jsonArray.length();j++){
					JSONObject jsonObject2 = jsonArray.getJSONObject(j);
					String url1=jsonObject2.getString("url1");
					String url2=jsonObject2.getString("url2");
					String url3=jsonObject2.getString("url3");
					String name1=jsonObject2.getString("name1");
					String name2=jsonObject2.getString("name2");
					String name3=jsonObject2.getString("name3");
					CategoryInfo categoryInfo2=new CategoryInfo(title, url1, url2, url3, name1, name2, name3,false);
					categoryInfos.add(categoryInfo2);
				}
				
			}
			return categoryInfos;
			
		} catch (JSONException e) {
			e.printStackTrace();
			return null;
		}
	
	}
	@Override
	public String getKey() {
		return "category";
	}
}

布局（三个这）

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:clickable="false"
    android:orientation="horizontal"
    android:paddingLeft="5dp"
    android:paddingRight="5dp" >
    <RelativeLayout
        android:id="@+id/rl_1"
        android:layout_width="0dip"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:background="@drawable/grid_item_bg"
        android:clickable="true"
        android:paddingBottom="10dp"
        android:paddingTop="10dp" >
        <ImageView
            android:id="@+id/iv_1"
            android:layout_width="55dp"
            android:layout_height="55dp"
            android:layout_centerHorizontal="true"
            android:scaleType="fitXY"
            android:src="@drawable/ic_default" />
        <TextView
            android:id="@+id/tv_1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_below="@id/iv_1"
            android:layout_centerHorizontal="true"
            android:textColor="#ff7a7a7a" />
    </RelativeLayout>

CategoryContentHolder 

public class CategoryContentHolder extends BaseHolder<CategoryInfo> {
	ImageView [] ivs;
	TextView [] tvs;
	@Override
	public View initView() {
		View view=UiUtils.inflate(R.layout.item_category_content);
		ivs=new ImageView[3];
		ivs[0]=(ImageView) view.findViewById(R.id.iv_1);
		ivs[1]=(ImageView) view.findViewById(R.id.iv_2);
		ivs[2]=(ImageView) view.findViewById(R.id.iv_3);
		
		tvs=new TextView[3];
		tvs[0]=(TextView) view.findViewById(R.id.tv_1);
		tvs[1]=(TextView) view.findViewById(R.id.tv_2);
		tvs[2]=(TextView) view.findViewById(R.id.tv_3);
		
		
		return view;
	}
	@Override
	public void refreshView(CategoryInfo data) {
		// 第一块 
		if(!TextUtils.isEmpty(data.getName1())&&!TextUtils.isEmpty(data.getUrl1())){
			tvs[0].setText(data.getName1());
			bitmapUtils.display(ivs[0], HttpHelper.URL+"image?name="+data.getUrl1());
			tvs[0].setVisibility(View.VISIBLE);
			ivs[0].setVisibility(View.VISIBLE);
		}else{
			tvs[0].setVisibility(View.INVISIBLE);
			ivs[0].setVisibility(View.INVISIBLE);
		}
		// 第二块
		if(!TextUtils.isEmpty(data.getName2())&&!TextUtils.isEmpty(data.getUrl2())){
			tvs[1].setText(data.getName2());
			bitmapUtils.display(ivs[1], HttpHelper.URL+"image?name="+data.getUrl2());
			tvs[1].setVisibility(View.VISIBLE);
			ivs[1].setVisibility(View.VISIBLE);
		}else{
			tvs[1].setVisibility(View.INVISIBLE);
			ivs[1].setVisibility(View.INVISIBLE);
		}
		//第三块
		if(!TextUtils.isEmpty(data.getName3())&&!TextUtils.isEmpty(data.getUrl3())){
			tvs[2].setText(data.getName3());
			bitmapUtils.display(ivs[2], HttpHelper.URL+"image?name="+data.getUrl3());
			tvs[2].setVisibility(View.VISIBLE);
			ivs[2].setVisibility(View.VISIBLE);
		}else{
			tvs[2].setVisibility(View.INVISIBLE);
			ivs[2].setVisibility(View.INVISIBLE);
		}
	}
}

CategoryTitleHolder 

public class CategoryTitleHolder extends BaseHolder<CategoryInfo> {
	private TextView tv;
	@Override
	public View initView() {
		tv = new TextView(UiUtils.getContext());
		tv.setTextColor(Color.BLACK);
		tv.setBackgroundDrawable(UiUtils.getDrawalbe(R.drawable.grid_item_bg));
		return tv;
	}
	@Override
	public void refreshView(CategoryInfo data) {
		tv.setText(data.getTitle());
	}
}

CategoryFragment （ 注意CategoryAdapter）

public class CategoryFragment extends BaseFragment {
	private List<CategoryInfo> datas;
	public static int ITEM_TITLE =2;
	// 创建成功的界面
	@Override
	public View createSuccessView() {
		BaseListView listView = new BaseListView(UiUtils.getContext());
		listView.setAdapter(new CategoryAdapter(datas, listView));
		return listView;
	}
	private class CategoryAdapter extends DefaultAdapter<CategoryInfo> {
		private int position;// 当前条目位置记录
		public CategoryAdapter(List<CategoryInfo> datas, ListView lv) {
			super(datas, lv);
		}
		// 实现每个条目的界面
		@Override
		protected BaseHolder<CategoryInfo> getHolder() {
			if (!datas.get(position).isTitle()) {
				return new CategoryContentHolder();
			}else{
				return new CategoryTitleHolder();
			}
		}
		@Override
		public View getView(int position, View convertView, ViewGroup parent) {
			this.position = position;
			return super.getView(position, convertView, parent);
		}
		@Override
		protected boolean hasMore() { // 当前方法 如果为false onload就不会被调用了
			return false;
		}
		@Override
		protected int getInnerItemViewType(int position) {
			if (datas.get(position).isTitle()) {
				return ITEM_TITLE;
			} else {
				return super.getInnerItemViewType(position);
			}
		}
		@Override
		protected List<CategoryInfo> onload() {
			return null;
		}
		//  集合 管理三个convertView   
		@Override
		public int getViewTypeCount() {
			return super.getViewTypeCount() + 1; // 又额外多了一种条目类型  现在又三种  1 标题 2 内容 3 加载更多(没有显示)
		}
	}
	// 请求服务器
	@Override
	protected LoadResult load() {
		CategoryProtocol protocol = new CategoryProtocol();
		datas = protocol.load(0);
		return checkData(datas);
	}
}

修改DefaultAdapter

	public View getView(int position, View convertView, ViewGroup parent) {
		BaseHolder holder = null;
		switch (getItemViewType(position)) {  // 判断当前条目时什么类型
		case MORE_ITEM:
			if(convertView==null){
				holder=getMoreHolder();
			}else{
				holder=(BaseHolder) convertView.getTag();
			}
			break;
		default:
			if (convertView == null) {
				holder = getHolder();
			} else {
				System.out.println("aaa");
				holder = (BaseHolder) convertView.getTag();
			}
			if (position < datas.size()) {
				holder.setData(datas.get(position));
			}
			break;
		}
		return holder.getContentView();  //  如果当前Holder 恰好是MoreHolder  证明MoreHOlder已经显示
	}
	private MoreHolder holder;
	private BaseHolder getMoreHolder() {
		if(holder!=null){
			return holder;
		}else{
			holder=new MoreHolder(this,hasMore());
			return holder;
		}
	}
	/**
	 * 是否有额外的数据
	 * @return
	 */
	protected boolean hasMore() {
		return true;
	}
