json格式解析在android的应用

服务器servlet端查询数据打印在网页上保存为json格式(记得只是一个对象...)

public void doGet(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {

		response.setContentType("text/html; charset=UTF-8");
		PrintWriter out = response.getWriter();
		DBQueryImpl queryImpl = new DBQueryImpl();

		ItemParent item = queryImpl.getItemParent();
		JSONArray array = JSONArray.fromObject(item);
		// System.out.println("jason===========>" + array.toString());
		// 打印到网页上,不要打印方括号
		// out.write(array.toString());
		for (Object object : array) {
			System.out.print(object);
			out.write(object.toString());
		}

		out.flush();
		out.close();
	}

android客户端获取数据并解析

private String[] getItemParent() {
		String[] array = null;
		// 从网页获取数据

//	http://192.168.1.101:8080/epay_server/QueryParentServlet
		String urlPath = GlobalConstant.SERVLET_QUERYPARENTITEM_URL;

		HttpClient client = new DefaultHttpClient();
		HttpPost post = new HttpPost(urlPath);
		try {
			InputStream responseStream = client.execute(post).getEntity()
					.getContent();
			// 记得转换成gbk编码
			BufferedReader bufferedReader = new BufferedReader(
					new InputStreamReader(responseStream, "UTF-8"));
			String webContentString = bufferedReader.readLine();

			ItemParent item = new Gson().fromJson(webContentString,
					ItemParent.class);
			ArrayList<String> list = item.getItem();
			// 转成数组
			array = (String[]) list.toArray(new String[list.size()]);
			System.out.println("parent>>>>>>>>>>"+Arrays.toString(array));

		} catch (Exception e) {
			// TODO: handle exception
		}
		return array;
