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 block
e.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 block
e.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
