我想解析一个嵌套的jsonarray
JSONParser jParser = new JSONParser();
// getting JSON string from URL
JSONObject json = jParser.getJSONFromUrl(url);
try {
dialogcreated = json.getJSONArray(TAG_DETAILS);
// Log.d("apptoken",login.toString());
for (int i = 0; i < dialogcreated.length(); i++) {
JSONObject d = dialogcreated.getJSONObject(i);
String msg = d.getString(TAG_MSG);
dialogs = d.getJSONArray("dialogdetails");
我收到jsonobject cannot be converted to jsonarray
错误
dialogs = d.getJSONArray("dialogdetails");
行
我的json数组
{"dialog_details":[{"msg":"success","dialogdetails":{"dialog_id":"139","dialog_category":"2","dialog_title":"apptesting1","dialog_description":"apptesting2","dialog_image":null,"dialog_type":"P","mem_id":"27","temp_moderator_assigned":"0","moderator_assigned":"0","created_on":"6 minutes ago","updated_by":null,"updated_on":"6 minutes ago","mem_dialog_type":"P","published":"0","dialog_status":"1","dialog_archived":"0","dialog_votes":"0","featured":"0","dialog_members":"0","dialog_posts":"0","wtavg":"0","d_member_username":"icube2","d_mem_id":"27","d_member_avatar":"0","d_member_email":"icube1solutions@gmail.com","d_category_id":"2","d_category_name":"Games"}}]}
答案 0 :(得分:0)
{ // json object
"dialog_details": [ // json array
{
"msg": "success",
"dialogdetails": { // json object
"dialog_id": "139",
dialogdetails
不是JSONArray,而是JSONObject
更改为JSONObject
dialogs = d.getJSONArray("dialogdetails");
到
JSONObject dialogs = d.getJSONObject("dialogdetails");
[
表示json数组节点
{
表示json对象节点
JSONObject jb = new JSONObject("myjsonstring");
JSONArray jr = (JSONArray)jb.getJSONArray("dialog_details"):
for(int i=0;i<jr.length();i++)
{
JSONObject d = (JSONObject) jr.getJSONObject(i);
String msg = d.getString(TAG_MSG);
JSONObject dialogs = d.getJSONObject("dialogdetails");
String dialog_id= dialogs.getString("dialog_id");
}

dialogdetails 不是JsonAray ..
你在这里做错了
dialogs = d.getJSONArray("dialogdetails");//Wrong
它是一个JsonObject
dialogs = d.getJSONObject("dialogdetails");
JSON字符串以大括号开头{代表JsonObject
"dialogdetails": {
"dialog_id": "139",
"dialog_category": "2",
"dialog_title": "apptesting1",
"dialog_description": "apptesting2",
