android 解析json数据格式

android 解析json数据的两个方法分享：

一.简单解析

{"userbean":{"Uid":"100196","Showname":"\u75af\u72c2\u7684\u7334\u5b50","Avtar":null,"State":1}}

分析代码如下：

                int res = 0; 
                res = httpClient.execute(httpPost).getStatusLine().getStatusCode(); 
                if (res == 200) { 
                    /* 
                     * 当返回码为200时，做处理 
                     * 得到服务器端返回json数据，并做处理 
                     * */ 
                    HttpResponse httpResponse = httpClient.execute(httpPost); 
                    StringBuilder builder = new StringBuilder(); 
                    BufferedReader bufferedReader2 = new BufferedReader( 
                            new InputStreamReader(httpResponse.getEntity().getContent())); 
                    String str2 = ""; 
                    for (String s = bufferedReader2.readLine(); s != null; s = bufferedReader2 
                            .readLine()) { 
                        builder.append(s); 
                    } 
                    Log.i("cat", ">>>>>>" + builder.toString());

                 JSONObject jsonObject = new JSONObject(builder.toString()) .getJSONObject("userbean"); 

                String Uid; 
                String Showname; 
                String Avtar; 
                String State; 

                Uid = jsonObject.getString("Uid"); 
                Showname = jsonObject.getString("Showname"); 
                Avtar = jsonObject.getString("Avtar"); 
                State = jsonObject.getString("State");

二.带有数组的解析方法：

代码如下：

JSONObject jsonObject = new JSONObject(jsonString).getJSONObject("errorcode");
			errorcode = jsonObject.getString("errorcode");
			code = Integer.parseInt(errorcode);
			
			DicktAdapter.items.clear();
			if (code == 0) {
				JSONObject jsonObject1 = new JSONObject(jsonString).getJSONObject("data");
				JSONArray jsonArray = jsonObject1.getJSONArray("dick");
				for (int i = 0; i < jsonArray.length(); i++) {
			            JSONObject jsonDick = (JSONObject)jsonArray.opt(i); 
				    dick = new Dick();
				    dick.setContent(jsonDick.getString("content"));
				    dick.setFrom(jsonDick.getString("from"));
				    dick.setTypeid(jsonDick.getString("typeid"));
				    dick.setErrorcode((Integer.parseInt(jsonDick.getString("errorcode"))));
				    adapter.addItems(dick);
				}
				
			}
