我有以下代码
public static ArrayList<NameValuePair> getParticipants(String jData)throws JSONException{
JSONObject jObj = new JSONObject(jData);
ArrayList<NameValuePair> partyList = new ArrayList<NameValuePair>();
JSONArray jPartyArr = jObj.getJSONArray("participate_users"); <-- ERROR HERE
servResponse = (int) jObj.getInt("returnCode");
if(servResponse == 1){
for(int i=0; i<jPartyArr.length(); i++){
JSONObject obj = jPartyArr.getJSONObject(i);
partyList.add(new BasicNameValuePair("account", obj.getString("account_id")));
partyList.add(new BasicNameValuePair("name", obj.getString("realname")));
}
}
return partyList;
}
以下JSON:
{
"returnCode": "1",
"result": {
"chat_group_id": "82",
"participate_users": [
{
"account_id": "328",
"realname": "Jessica"
},
{
"account_id": "360",
"realname": "Chloe"
}
]
}
}
但是我收到以下错误:
org.json.JSONException: No value for participate_users
我有一种感觉,我不小心忽略了JSON格式。有人可以指出我正确的方向吗?

你需要在下面一层。
试试这个 - JSONArray jPartyArr = jObj.getJSONObject("result").getJSONArray("participate_users");
