<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Below will reference with our custom style -->
    <item name="android:textAppearance">@style/my_tab_text</item>
</style>

<style name="my_tab_text" parent="Base.TextAppearance.AppCompat">
    <item name="android:textColor">@android:color/holo_blue_dark</item>
</style>

 <android.support.design.widget.TabLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            app:tabTextAppearance="@style/my_tab_text"
            app:tabIndicatorHeight="48dp"/>

if you need zooming effect very close 
LatLng latLng = new LatLng(location.getLatitude(), location.getLongitude());
  
/*   CameraPosition cameraPosition = new CameraPosition.Builder()
      .target(latLng).zoom(19f).tilt(70).build();

      googleMap.animateCamera(CameraUpdateFactory
              .newCameraPosition(cameraPosition));*/
