java - Tabs in TabLayout not filling up entire ActionBar

Question

I am using a TabLayout and ViewPager to display ActionBar tabs following the guide Google Play Style Tabs using TabLayout, however my tabs are squished to the left side of the ActionBar, shown below:

And I would like them to take up the whole bar with equal widths. I've made only a few minor changes to the guide:

In activity_main.xml a style was created to show the ActionBar:

<android.support.design.widget.TabLayout
  android:id="@+id/sliding_tabs"
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  style="@style/AppTheme"
  app:tabMode="scrollable" />

Here is the styles.xml code:

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
  <item name="windowActionBar">true</item>
  <item name="tabIndicatorColor">#ffff0030</item>
</style>

Also, my MainActivity now extends AppCompatActivity instead of a FragmentActivity.

Simple answer which I got from here.

You just put this in your xml code :

<android.support.design.widget.TabLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            app:tabMaxWidth="0dp"
            app:tabGravity="fill"
            app:tabMode="fixed" />
