Tabs in TabLayout not filling up entire ActionBar

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" />

Set TabLayout width to match Parent

Like this.

<TabLayout
    android:layout_width="match_parent"
    android:layout_height="60dp"/>

You can refer to the TabLayout.

GRAVITY_CENTER Gravity used to lay out the tabs in the center of the TabLayout.

GRAVITY_FILL Gravity used to fill the TabLayout as much as possible.

MODE_FIXED Fixed tabs display all tabs concurrently and are best used with content that benefits from quick pivots between tabs.

MODE_SCROLLABLE Scrollable tabs display a subset of tabs at any given moment, and can contain longer tab labels and a larger number of tabs.

Set this in your code or your layout xml.

app:tabGravity="center"
app:tabMode="fixed"

or 

tabLayout.setTabGravity(TabLayout.GRAVITY_CENTER);
tabLayout.setTabMode(TabLayout.MODE_FIXED);

Generally, using the code like blow can work without setting tabGravity and tabMode.

<android.support.design.widget.AppBarLayout
    android:id="@+id/appbar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
        app:layout_scrollFlags="scroll|enterAlways" />

    <android.support.design.widget.TabLayout
        android:id="@+id/tabs"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

</android.support.design.widget.AppBarLayout>

Add - app:tabGravity="fill" property in the xml.

For Example - 

<android.support.design.widget.TabLayout
        android:id="@+id/tablayout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:tabGravity="fill" />

Try adding this to MainActivity:

tabLayout.setTabMode(TabLayout.MODE_FIXED);
tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);
