Parsing nested JSON in ANDROID [closed]

Answer 1

I always use Gson library from Google : https://code.google.com/p/google-gson/ and To generate POJO I use online utilities like this one http://www.jsonschema2pojo.org/ or this one http://jsongen.byingtondesign.com/. After that its a matter of writing one line to generate or parse any json. I have never parsed json manually.

Answer 2

You can use a Java library called JSONSimple that will do it for you.link

Answer 3

You basically have here an object, which contains an object that called topDrops inside it you have a string called week, and an array called player. Each object in this array contains a string called percent and a string called id. After that you have another two strings version and encoding.

I won't write you the whole parsing method, but I recommend you to go over this blog post I wrote on this subject, from it you can understand how to parse this object with what android gives you and using the Gson library, there is a project there you can download and experiment with.

Answer 4

I hope it help you! :) This's my solution.

Integer Week;
String Version, Encoding;
ArrayList<Double> Percent;
ArrayList<Integer> ID;

JSONObject jObject = new JSONObject(...JSON String...);
JSONObject TopDrops = jObject.getJSONObject("topDrops");
Week = TopDrops.getInt("week");

JSONArray Player = TopDrops.getJSONArray("player");
for (int i = 0; i < 5; i++) {
     Percent.add(Player.getJSONObject(i).getDouble("percent"));
     ID.add(Player.getJSONObject(i).getInt("id"));
}
Version = TopDrops.getString("version");
Encoding = TopDrops.getString("encoding");

Can you send url with this JSON?

Answer 5

Here is my code for parsing json from an URL :

public JSONObject getJSONFromUrl(String url) {
try {
    // defaultHttpClient
    DefaultHttpClient httpClient = new DefaultHttpClient();
    HttpPost httpPost = new HttpPost(url);
    HttpResponse httpResponse = httpClient.execute(httpPost);
    HttpEntity httpEntity = httpResponse.getEntity();
    json = EntityUtils.toString(httpEntity);
} catch (UnsupportedEncodingException e) {
    e.printStackTrace();
} catch (ClientProtocolException e) {
    e.printStackTrace();
} catch (IOException e) {
    e.printStackTrace();
}
JSONObject jObj;
// try parse the string to a JSON object
try {
    jObj = new JSONObject(json);
} catch (JSONException e) {
    Log.e("JSON Parser", "Error parsing data " + e.toString());
}
Log.v("debug", "JSON ready to parsing");
return jObj;
}

public void parsingData(JSONObject json) {
try {
    JSONArray data = json.getJSONArray("data");
    for (int i = 0; i < data.length(); i++) {
        // Do your stuff, example :
        JSONObject c = data.getJSONObject(i);
        JSONObject topDrops = c.getJSONObject("topDrops");
        JSONArray playerArray = topDrops.getJSONArray("player");
        // playerArray.getJSONObject(0) == first player
    }
} catch (JSONException e) {
    e.printStackTrace();
    Log.v("debug", "Error during the connection HTTP");
    cancel(Boolean.TRUE);
}
}
