    <p>I have a JSON Object that looks like this : </p> <pre><code>"TripList":{ "noNamespaceSchemaLocation":"http://api.vasttrafik.se/v1/hafasRestTrip.xsd", "servertime":"11:27", "serverdate":"2013-04-02", "Trip":[{ "Leg":{ "name":"Spårvagn 3", "type":"TRAM", "id":"9015014500300079", "direction":"Kålltorp", "fgColor":"#004b85", "bgColor":"#ffffff", "stroke":"Solid", "accessibility":"wheelChair", "Origin":{ "name":"Brunnsparken, Göteborg", "type":"ST", "id":"9022014001760004", "routeIdx":"19", "time":"11:27", "date":"2013-04-02", "track":"D ", "rtTime":"11:31", "rtDate":"2013-04-02", "$":"\n" } </code></pre> <p>to get the name inside the Leg object is working fine. But if I wanna get thetime inside the Origin object how do I do that?</p> <p>My code is like this so far:</p> <pre><code> JSONParser parser = new JSONParser(); Object obj = parser.parse(Planner.getPlanner().getJsonDataForTrip(Planner.getPlanner().getStartLocationID(), Planner.getPlanner().getDestinationID())); JSONObject topObject = (JSONObject) obj; JSONObject locationList = (JSONObject) topObject.get("TripList"); JSONArray array = (JSONArray) locationList.get("Trip"); Iterator&lt;JSONObject&gt; iterator = array.iterator(); while (iterator.hasNext()) { JSONObject jsonObj = iterator.next(); jsonObj = (JSONObject) jsonObj.get("Leg"); String line = (String) jsonObj.get("name"); Planner.getPlanner().setLines(line); System.out.println(jsonObj.get("Origin")); Long time = (Long) jsonObj.get("time"); String track =(String) jsonObj.get("track"); System.out.println(line); System.out.println(time); System.out.println(track); } </code></pre> <p>}</p> <pre><code>And in the console it say like this : </code></pre> <blockquote> <p>{"routeIdx":"19","id":"9022014001760004","rtDate":"20130402","time":"15:02","$":"\n","name:"Brunnsparken, Göteborg","track":"D ","rtTime":"15:06","date":"2013-04-02","type":"ST"}</p> <p>Spårvagn 3</p> <p>null</p> <p>null</p> </blockquote> <p>So basiclly i am getting the name Spårvang 3 already. But I wanna get the time.</p> <p>so the time that I am trying to get out by using <code>jsonObj.get("time");</code> is giving a <code>null</code> value.</p> <p>Whats the problem and how can I get the time from the object "Origin"??</p>

    1. CO"time" is inside "Origin" and not "Leg". Also, **time is not Long**. You need to use SimpleDateFormat to parse it. perhaps you'd like to use "date" to parse it.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
