android 解析json数据格式

json数据格式解析我自己分为两种；

一种是普通的，一种是带有数组形式的；




普通形式的：
服务器端返回的json数据格式如下：

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

分析代码如下：

//TODO状态处理500200
intres=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
**/
HttpResponsehttpResponse=httpClient.execute(httpPost);
StringBuilderbuilder=newStringBuilder();
BufferedReaderbufferedReader2=newBufferedReader(
newInputStreamReader(httpResponse.getEntity().getContent()));
Stringstr2="";
for(Strings=bufferedReader2.readLine();s!=null;s=bufferedReader2
.readLine()){
builder.append(s);
}
Log.i("cat",">>>>>>"+builder.toString());

JSONObjectjsonObject=newJSONObject(builder.toString())
.getJSONObject("userbean");

StringUid;
StringShowname;
StringAvtar;
StringState;

Uid=jsonObject.getString("Uid");
Showname=jsonObject.getString("Showname");
Avtar=jsonObject.getString("Avtar");
State=jsonObject.getString("State");
带数组形式的：
服务器端返回的数据格式为：

{"calendar":
{"calendarlist":
[
{"calendar_id":"1705","title":"(\u4eb2\u5b50)ddssd","category_name":"\u9ed8\u8ba4\u5206\u7c7b","showtime":"1288927800","endshowtime":"1288931400","allDay":false},
{"calendar_id":"1706","title":"(\u65c5\u884c)","category_name":"\u9ed8\u8ba4\u5206\u7c7b","showtime":"1288933200","endshowtime":"1288936800","allDay":false}
]
}
}

分析代码如下：

//TODO状态处理500200
intres=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
**/
HttpResponsehttpResponse=httpClient.execute(httpPost);
StringBuilderbuilder=newStringBuilder();
BufferedReaderbufferedReader2=newBufferedReader(
newInputStreamReader(httpResponse.getEntity().getContent()));
Stringstr2="";
for(Strings=bufferedReader2.readLine();s!=null;s=bufferedReader2
.readLine()){
builder.append(s);
}
Log.i("cat",">>>>>>"+builder.toString());
/**
*这里需要分析服务器回传的json格式数据，
*/
JSONObjectjsonObject=newJSONObject(builder.toString())
.getJSONObject("calendar");
JSONArrayjsonArray=jsonObject.getJSONArray("calendarlist");
for(inti=0;i<jsonArray.length();i++){
JSONObjectjsonObject2=(JSONObject)jsonArray.opt(i);
CalendarInfocalendarInfo=newCalendarInfo();
calendarInfo.setCalendar_id(jsonObject2.getString("calendar_id"));
calendarInfo.setTitle(jsonObject2.getString("title"));
calendarInfo.setCategory_name(jsonObject2.getString("category_name"));
calendarInfo.setShowtime(jsonObject2.getString("showtime"));
calendarInfo.setEndtime(jsonObject2.getString("endshowtime"));
calendarInfo.setAllDay(jsonObject2.getBoolean("allDay"));
calendarInfos.add(calendarInfo);
}
