5.2功能实现
5.2.1 新闻模块
用户进入热点新闻界面，即可浏览到实时热点新闻列表，每个列表项点击进去之后可以进入新闻详情界面获取该项新闻的详细信息。新闻模块如图5.2所示：
图5.2 新闻模块图
主要实现代码如下所示：
private ArrayList<HotNews.ShowapiResBodyEntity.PagebeanEntity.ContentlistEntity> hotNewsListData;
private int pageNum = 1;
@Override
protected ArrayList<HotNews.ShowapiResBodyEntity.PagebeanEntity.ContentlistEntity> requestData() {
pageNum = 1;
hotNewsListData = loadNewsData(pageNum);
return hotNewsListData;
}
private ArrayList<HotNews.ShowapiResBodyEntity.PagebeanEntity.ContentlistEntity> loadNewsData(int pageNum) {
HotNews hotNewsData = null;
ArrayList<HotNews.ShowapiResBodyEntity.PagebeanEntity.ContentlistEntity> hotNewsListData = null;
try{
String urlString = Url.getNewsDataUrl(pageNum);
HttpHelper.HttpResult httpResult = HttpHelper.get(urlString);
String resultString = httpResult.getString();
LogUtil.e("resultString--"+resultString);
hotNewsData = processNewsData(resultString);
if(hotNewsData!=null){
if(hotNewsData.getShowapi_res_code()==-1){
hotNewsListData = new ArrayList<HotNews.ShowapiResBodyEntity.PagebeanEntity.ContentlistEntity>();
}else {
hotNewsListData = (ArrayList<HotNews.ShowapiResBodyEntity.PagebeanEntity.ContentlistEntity>) hotNewsData.getShowapi_res_body().getPagebean().getContentlist();
ArrayList<HotNews.ShowapiResBodyEntity.PagebeanEntity.ContentlistEntity> uselessData =
