您好我正在尝试解析另一个json数组中的json数组。帮助我。
我的Json数组是
"results":[
{
"percentcompleted":0,
"requirers":[
{
"activityContext":null,
"auditReason":null,
"assignee":{
"sourceType":"InternalPerson",
"activitySourceType":{
"listId":"sysli000000000003037",
"sourceType":0,
"key":"0",
"displayName":"Person"
},
"locale":{
"id":"local000000000000001",
"displayName":"English"
},
"id":"emplo000000006156648",
"displayName":"Venkat Rao"
},
"targetDate":null,

],

},
"targetDate":null,

"owner":{

"id":"stcur000000000003182",
"assigneeAdditionalDetails":{
"person_no":"VRAO",
"username":"VRAO"
}
},
"isgranted":null
},
我的代码解析上面的数据是
public class CurriculaParser {
public ArrayList<CurriculaData> getData(String response)
{
ArrayList<CurriculaData> dataList = new ArrayList<>();
try {
JSONObject mainObj = new JSONObject(response);
JSONArray array = mainObj.getJSONArray("results");
CurriculaData data;
for(int i = 0;i<array.length();i++)
{
data = new CurriculaData();
JSONObject resObj = array.getJSONObject(i);
JSONArray reqArray = resObj.getJSONArray("requires");
for( int j =0;j<reqArray.length();j++) {
JSONObject reqObj = reqArray.getJSONObject(j);
JSONObject innerObj = reqObj.getJSONObject("learningEvent");
data.setTitle(innerObj.getString("displayName"));
data.setAssignedOn(reqObj.getString("assignedOn"));
}
JSONArray basicDetailArray = resObj.getJSONArray("basicdetail");
for(int k=0;k<basicDetailArray.length();k++) {
JSONObject basicDetailObj = basicDetailArray.getJSONObject(k);
JSONObject statusObj = basicDetailObj.getJSONObject("status");
data.setStatus(statusObj.getString("displayName"));
data.setAcquiredOn(basicDetailObj.getString("acquiredOn"));
JSONObject assignObj = basicDetailObj.getJSONObject("assignee");
data.setAssignedBy(assignObj.getString("displayName"));
}
dataList.add(data);
}
} catch (Exception e) {
e.printStackTrace();
}
return dataList;
}
最后我得到了像
这样的错误org.json.JSONException：没有值
让我知道我所做的错误，我是一个初学者，在另一个jsonarray中处理jsonarray
答案 0 :(得分：1)
org.json.JSONException：没有值
KEY 查找不匹配您应该传递 requirers ，而不是 requires 。
JSONArray reqArray = resObj.getJSONArray("requirers");
答案 1 :(得分：1)
