       app:tabMode="fixed"
       app:tabSelectedTextColor="@color/white"
       app:tabTextColor="@color/white"
       />

Answer 1

You should add tabMaxWidth.

The maximum width for tabs.

May be a dimension value, which is a floating point number appended with a unit such as "14.5sp". Available units are: px (pixels), dp (density-independent pixels), sp (scaled pixels based on preferred font size), in (inches), and mm (millimeters) .

<android.support.design.widget.TabLayout
      app:tabMaxWidth="0dp"
       />

You can check Tabs in TabLayout not filling up .
