Launch Activity for a certain record
<p>I have an screen that displays all the names in the Contacts in a ListView.  </p>

<p>When the user clicks on a name, I want to launch another Activity which display the details of the selected Contact (Phone number/ email) in another screen. How do I display details for the <em>selected</em> row. (i.e When starting the intent how do I send over the row_id of the item selected)? </p>

<p>I've tried the following code:</p>

<pre><code>    Intent i = new Intent(this, ContactDetails.class);
    startActivity(i);
</code></pre>
