    <p>It's perhaps a good time to switch to an <a href="http://developer.android.com/reference/android/widget/ArrayAdapter.html" rel="nofollow noreferrer">ArrayAdapter</a>. I recommend to transfer the JSON into a custom model bean first:</p> <pre><code>class Person { long id; String phone, name, age; } </code></pre> <p>Then you can use an JSON parser library like <a href="https://code.google.com/p/google-gson/" rel="nofollow noreferrer">gson</a> to parse the array into a <code>List&lt;Person&gt;</code> and use this array to drive your list. (See <a href="https://stackoverflow.com/questions/6932332/gson-help-with-parse-array-works-without-array-but-wont-with-array">Gson help with parse array - works without array but won&#39;t with array</a>) for an example on the parsing.</p> <p>Finally, when you are ready to write back the data, simply re-generate the JSON from the array. This question got an example for that: <a href="https://stackoverflow.com/questions/5813434/trouble-with-gson-serializing-an-arraylist-of-pojos">Trouble with Gson serializing an ArrayList of POJO&#39;s</a></p> <p>Pros:</p> <ul> <li>Once your JSON data model changes, only a small change in your model is needed to read the new format.</li> <li>You can use standard Java tools like ArrayList and POJOs</li> </ul> <p>Cons:</p> <ul> <li>You will need to import GSON or equivalent into your project. <ul> <li>Also check this question: <a href="https://stackoverflow.com/questions/9605913/how-to-parse-json-in-android">How to parse JSON in Android</a></li> </ul></li> </ul>

    1. COHi Sebastian, Thanks for helping. I add more informations. My json file still enter the mobile users, and will be in this format, as an array, `"phone": {                       "mobile": "+91 0000000000"                       "home": "00 000000"                       "office": "00 000000"`                  }. With the solution you sent, I can do this?

    3. COI added the phones in the array and it worked. But I still have doubts about how to get the item 22 and update it. How is the code snippet?

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.
