Changing background color of ListView items on Android

How can I change background color of ListView items on a per-item basis. When I use android:backgroundColor in the ListView item layout I can achieve this, however the list selector is no longer visible. I can make the selector visible again by setting drawSelectorOnTop to true but then the selector overlays the whole item.

Any ideas how to change those background colors and keep the selector?

PS I would rather not change the selector itself.

EDIT: Authors of GMail application have managed to achieve exactly this so it's definitely possible.

Take a look at List14 example. In getView() you can call convertView.setBackgroundDrawable() for each entry. You could have a class member counter to decide which background to call it with to get alternating backgrounds, for example.

If the setBackgroundColor is added for onItemClick event, it will not work unless you can put it after the click event.

Try to add debug code in the adapter's getView method, you will find that getView will be called again whenever you click on the screen. So, after you set the background color, the system will redraw the screen with original setting. Don't know why it waste resource to rebuild the screen whenever it's being click, there already have other way that we can notify the system to redraw the screen when needed.

Maybe you can add some control flag to determine the background color for individual row, then modify the getView method to set the color according to this control flag. So, the background color will be changed when it redraw the screen.

I'm also looking for an official solution on it.

That's what I used (Kotlin):

if(blablabla == "whatever") {
    view.setBackgroundColor(getColor(context, R.color.teal_200))
} else {
    view.setBackgroundColor(getColor(context, R.color.teal_700))
}
