android豆瓣apiv2电影/音乐/书籍搜索及图片异步下载/json解析

豆瓣api_v2版本开始返回的是json，然后android里面自带json解析的类库,所以感觉非常容易就解析了。

本实例采用了把搜索结果json解析到ListView中，图片异步下载，点击某个item跳转到详细信息的界面。

解析过程：

List<SingleEntity> result = new ArrayList<SingleEntity>();String ch = URLEncoder.encode(key, "utf-8");String uString = "http://api.douban.com/v2/movie/search?q=" + ch;URL url = new URL(uString);StringBuilder builder = new StringBuilder();BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(url.openStream()));for (String s = bufferedReader.readLine(); s != null; s = bufferedReader.readLine()) {builder.append(s);}JSONArray jsonArray = null;try {JSONObject jsonObject = new JSONObject(builder.toString());jsonArray = jsonObject.getJSONArray("subjects");} catch (JSONException e) {e.printStackTrace();}for (int i = 0; i < jsonArray.length(); i++) {JSONObject jsonObject = (JSONObject) jsonArray.opt(i);try {JSONObject imagesObj = jsonObject.getJSONObject("images");SingleEntity movieBriefPojo = new SingleEntity();movieBriefPojo.setMovieName(jsonObject.getString("title"));movieBriefPojo.setAuthorName(jsonObject.getString("year"));movieBriefPojo.setFirstUrl(jsonObject.getString("id"));movieBriefPojo.setImageUrl(imagesObj.getString("small"));result.add(movieBriefPojo);} catch (JSONException e) {// TODO Auto-generated catch blocke.printStackTrace();}}return result;}

这是搜索音乐然后解析结果：

public List<SingleEntity> findMusicXml(String keyworld) throws IOException {List<SingleEntity> result = new ArrayList<SingleEntity>();String ch = URLEncoder.encode(keyworld, "utf-8");String uString = "http://api.douban.com/v2/music/search?q=" + ch;URL url = new URL(uString);StringBuilder builder = new StringBuilder();BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(url.openStream()));for (String s = bufferedReader.readLine(); s != null; s = bufferedReader.readLine()) {builder.append(s);}JSONArray jsonArray = null;try {JSONObject jsonObject = new JSONObject(builder.toString());jsonArray = jsonObject.getJSONArray("musics");} catch (JSONException e) {e.printStackTrace();}for (int i = 0; i < jsonArray.length(); i++) {JSONObject jsonObject = (JSONObject) jsonArray.opt(i);try {JSONObject attrs = jsonObject.getJSONObject("attrs");JSONArray singerArray = attrs.getJSONArray("singer");SingleEntity movieBriefPojo = new SingleEntity();movieBriefPojo.setMovieName(attrs.getJSONArray("title").getString(0));movieBriefPojo.setAuthorName(singerArray.getString(0));movieBriefPojo.setFirstUrl(jsonObject.getString("id"));movieBriefPojo.setImageUrl(jsonObject.getString("image"));result.add(movieBriefPojo);} catch (JSONException e) {// TODO Auto-generated catch blocke.printStackTrace();}}return result;}

这是搜索书籍然后解析结果

public List<SingleEntity> findBookXml(String keyworld) throws Exception {{List<SingleEntity> result = new ArrayList<SingleEntity>();String ch = URLEncoder.encode(keyworld, "utf-8");String uString = "http://api.douban.com/v2/book/search?q=" + ch;URL url = new URL(uString);StringBuilder builder = new StringBuilder();BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(url.openStream()));for (String s = bufferedReader.readLine(); s != null; s = bufferedReader.readLine()) {builder.append(s);}JSONObject jsonObject = new JSONObject(builder.toString());JSONArray books = jsonObject.getJSONArray("books");for (int i = 0; i < books.length(); i++) {JSONObject book = (JSONObject) books.opt(i);SingleEntity bookSingleEntity = new SingleEntity();bookSingleEntity.setMovieName(book.getString("title"));//书本名称bookSingleEntity.setFirstUrl(book.getString("id"));//书籍具体的地址bookSingleEntity.setImageUrl(book.getString("image"));//书籍图片bookSingleEntity.setAuthorName(book.getJSONArray("author").optString(0));//作者result.add(bookSingleEntity);}return result;}}

其从图片的异步下载用了某个博客中的方法，但是我不记得详细地址了请原谅，下面是运行图
