由于项目中遇到了这个问题，所以在这里记录一下。
比如：请求到的JSON串：
{
"msg":"数据获取成功",
"success":true,
"data":[
{
"id":40,
"name":"美术",
"parentId":4,
"photoUrl":"[email protected]",
"enable":1,
"pos":2,
"visitUrl":"sysPxbPage",
"ord":0,
"related":"1",
"moduleType":"",
"cateList":[
{
"id":155,
"moduleId":40,
"name":"雕塑",
"photoUrl":"sysPxbPage/artPage/[email protected]",
"enable":1,
"createTime":1508498216000
}
]
},
{
"id":41,
"name":"书法",
"parentId":4,
"photoUrl":"[email protected]",
"enable":1,
"pos":2,
"visitUrl":"sysPxbPage",
"ord":0,
"related":"1",
"moduleType":"",
"cateList":[
{
"id":158,
"moduleId":41,
"name":"纂刻",
"photoUrl":"sysPxbPage/writingPage/[email protected]",
"enable":1,
"createTime":1508498326000
}
]
}
}比如：获取photoUrl的值：
JSONObject da = resultJson.getJSONObject("data");
JSONArray d = da .JSONArray("cateList");
JSONObject ob = (JSONObject)d.get(0); // 这里是得到第一个对象
String result = ob.getString("photoUrl");
若是获取success的值：
resultJson.getBooleanValue("success")；
