    <p>I know that there are a lot of posts about checkboxes within Listviews and I can honestly say that after reading a large majority of these, it has left me confused with a hurting brain.</p> <p>My code does not extend the ListViewActivity but does have a listview as part of a relative layout which sits within a tabhost.</p> <p>I have tried the focusable=false both against the textview and the checkbox, the textview behaves but the checkbox still overrides the focus of the listview item.</p> <p>If I only needed one textview then I would have gone for androids built in layout but I require at least 6 textviews with a checkox on each line.</p> <p>My Main.xml is this :</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;

    1. COI am going to re-attempt the examples from the anddev.org links and try and use these. Not sure though if they will work as I a not using extend ListActivity within my project as the Activity is also managing a tabhost as well.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
