Body
I have a JSON response that looks like this. I want to extract the values of "text" and put them into a Set of Strings (i.e. I don't necessarily need the entire JSON to be derialised). I am using the <a href="http://code.google.com/p/google-gson/" rel="nofollow">GSON</a> library So far my method looks like this (It's obviously wrong): <pre><code> public static Response deserialise(String json){ Gson gson = new Gson(); Response r = gson.fromJson(json, Response.class); return r; } </code></pre> I am calling <code>deserialise</code> with this: <pre><code>Response r = deserialise(json); System.out.println("[status]: "+r.getStatus()); // works fine Collection<Keyword> coll = r.getKeywords(); Iterator<Keyword> itr = coll.iterator(); while(itr.hasNext()){ System.out.println(itr.next().getWord()); //prints null every time } </code></pre> Response is a class with the following member variables (with getters and setters): <pre><code>private String status; private String usage; private String language; private Collection<Keyword> keywords; </code></pre> Keyword is a class with the following member variables (with getters and setters): <pre><code>private String word; private String relevance; </code></pre> The JSON looks like this: <pre><code>{ "status": "OK", "usage": "By accessing AlchemyAPI or using information generated by AlchemyAPI, you are agreeing to be bound by the AlchemyAPI Terms of Use: http://www.alchemyapi.com/company/terms.html", "url": "http://www.theage.com.au/world/aussie-trying-to-make-a-difference-gunned-down-20110510-1egnv.html", "language": "english", "keywords": [ { "text": "Mr McNichols", "relevance": "0.99441" }, { "text": "Ms Benton", "relevance": "0.392337" }, { "text": "Detroit", "relevance": "0.363931" }, { "text": "Crocodile Hunter", "relevance": "0.350197" } ] } </code></pre> The problem is that the Collection of Keywords returns null values - although it seems to have the correct size, which is positive.

Guidance

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.
