Highlighting the selected row in a ComponentView? - sencha-touch

Question

I'm working with this ComponentView example:
Kitten ComponentView
In my variation, I'd like to highlight the selected row when the user taps on it, as would happen in an xtype: 'list'. How can I accomplish this?

Answer 1

You can achieve this by using an tpl property and then set the class of the css inside the <div> tag
Something like this,
....
xtype: 'list',
tpl: '<div class="clickedItem"> ...'
....
and then write your css code as,
.clickedItem{
background: // some color value;
text-shadow: // some color value;
}

Answer 2

After examining the Sencha Kiva example in their examples directory,
it looks like it's a combination of the .x-dataview-UI_NAME class with .x-list-item, where UI_NAME is defined is the dataview view config. In the Kiva example, it's the line 'ui: loans'.
So, the CSS section looks something like this:
.x-dataview-loans .x-list-item {
...
}
Defining the UI suffix in the view:
Ext.define('Kiva.view.LoansList', {
extend: 'Ext.DataView',
xtype : 'loanslist',
requires: [
'Kiva.view.LoansListItem'
],
config: {
ui : 'loans',
store: 'Loans',
useComponents: true,
defaultType: 'loanslistitem',
deselectOnContainerClick: false
},
onItemTap: function(container, target, index, e) {
var me = this;
me.callParent(arguments); // WARNING: without this call, the row will not become selected
}

.x-dataview-loans .x-img {
