Personalizing the app's listview items by customizing the ui-icon arrow

Is there a way to customize the arrow image used for list items in a jQuery Mobile listview? How can I replace the default grey circle arrow with my own image? Do I need to override jQuery CSS classes for this task? My current setup uses jQuery Mobile 1.1.0RC version. Here is an example of HTML code for list items:

        <ul data-role="listview" id="list_id"> </ul>

And here is the JavaScript code I'm using to dynamically add list items:

var ap = "<li data-corners=\"false\" data-shadow=\"false\" data-iconshadow=\"true\" data-inline=\"false\" data-wrapperels=\"div\" data-icon=\"images/next.png\" data-iconpos=\"right\" data-theme=\"a\" class=\"ui-btn ui-btn-icon-right ui-li-has-arrow ui-li ui-li-has-thumb ui-btn-up-c\"><div class=\"ui-btn-inner ui-li\"><div class=\"ui-btn-text\"><a href=\"index.html\" class=\"ui-link-inherit\">"+
    "<img src=\"test_thumb.jpg\" class=\"ui-li-thumb\">"+
"<h3 class=\"ui-li-heading\">Big text</h3>"+
"<p class=\"ui-li-desc\">Smaller text</p>"+
"</a></div><span class=\"ui-icon ui-icon-arrow-r ui-icon-shadow\">&nbsp;</span</div</li>";

$('#list_id').append(ap);
$('#list_id').listview('refresh');

I've attempted changing the data-icon attribute to use my own image source, but it hasn't been successful. Any guidance and help on this matter would be greatly appreciated since I am relatively new to working with CSS and the jQuery framework. Thank you in advance!

Answer №1

If you want to use custom icons, make sure to provide a unique data-icon value such as myapp-email. The button plugin will then create a class by adding ui-icon- before the data-icon value and apply it to the button: ui-icon-myapp-email.

You can define a CSS rule in your stylesheet targeting the ui-icon-myapp-email class to specify the icon background source. For consistent visual appearance with other icons, design a white icon sized 18x18 pixels saved as PNG-8 with alpha transparency.

In this scenario, we are referring to an individual icon image, but you could also opt for an icon sprite and define the positioning accordingly, similar to the icon sprite utilized in the framework.

.ui-icon-myapp-email {
  background-image: url("app-icon-email.png");
}

Answer №2

To add your own touch to the mobile site, consider creating a new class with a unique image and styling it across all relevant elements.

Alternatively, you can swap out the default jQuery icon by locating the images folder where they are stored.
