How to skip json object (from json array) in android if it has an empty/null value?

Question

I'm developing an app where user can get list of other users, but i have to skip the users if they dont have completed their profile

ok take a look at my code:

Iterator<String> keys = json.keys();
                        while (keys.hasNext()) {
                            String key = keys.next();
                            JSONObject js = json.optJSONObject(key);
                            if (js != null) {
                                String user_info = js.getString("user_info");
                                user.setInfo(user_info);
                            } else {

                            }
                        }

what should i do in (else)

heres my json:

 "users": [
{
  "id": 73,
  "name": "Name",
  "lastname": "Lastname",
  "email": "",
  "create_date": 1469874203
},
{
  "id": 73,
  "name": "Name",
  "lastname": "Lastname",
  "email": "",
  "create_date": 1469874203
  "profile"{
           "address": string...
           "avatar": url...
      }

},

something like that

json doesn't support equalsIgnoreCase(""), its for the keys. and it didn't work. but thanx — Alimov Shohrukh

Do it like:

JSONObject jsonObject = new JSONObject(responseString);
JSONArray jsonArray = jsonObject.getJSONArray("users");
if(jsonArray.lenght() > 0){
    for(int i=0; i<jsonArray.length(); i++)
    {
        JSONObject object = jsonArray.getJSONObject(i);
        if(object.has("profile")){
            Iterator<String> keys = object.keys();
            while (keys.hasNext()) {
                String key = keys.next();
                if(TextUtils.isEmpty(key)){
                    break;
                }
                else{
                    User user = new User();
                    //parse and save user details
                }
            }
        }
    }
}

I have edited your if condition. Have you checked it?

Alimov Shohrukh Over a year ago

of course i did, but it still gets me the users, but without "user_info" only

Megha Maniar Over a year ago

can you post your json please?

Megha Maniar Over a year ago

so you want to get user only if it has a "profile" JSONObject right?

i tried it, it still shows the users without profiles + not showing profiles of other users

It can be done by using this code,

if (myObject.has("object_name") && !myObject.isNull("object_name")) {
    // Consider this user.
  }else{
    // Avoid this user.
  }

Also you can directly check the null by myObject.isNull("object_name") in if block. Hope this helps!
