Changing ActionBar tabs underline color programmatically

Question

I have created the action bar by

ActionBar actionbar = getActionBar()

The background of the action bar is changed by

actionbar.setBackgroundDrawable(actionBarBackgroundImage);

Now I need to change the action bar tabs underline color programmatically. Is there any method to change the action bar tabs underline color?

Answer 1

Alternatively you could use Android Action Bar Style Generator to easily theme your action bar and tabs.

Answer 2

Here is a much easier way. I know you were looking for a programmatic change, but this one is REALLY easy.

I've been struggling with this for days, but finally found the solution. I'm using AppCompat. You can set colorAccent in your theme and that will change the highlight color on your ActionBar. Like so:

<item name="colorAccent">@color/highlightcolor</item>

Here it is in context:

<style name="LightTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="colorPrimary">@color/darkgrey</item>
    <item name="colorPrimaryDark">@color/black</item>
    <item name="colorAccent">@color/highlightcolor</item>
</style>
