In your Xml file on which you are using TabLayout

       <android.support.design.widget.TabLayout
            android:id="@+id/tab_layout"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="@color/white"
            android:minHeight="?attr/actionBarSize"
            android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
            app:tabSelectedTextColor="@color/colorAccent"
            app:tabBackground="@color/tab_color"
            app:tabTextAppearance="@android:style/TextAppearance.Widget.TabWidget"
            app:tabTextColor="@color/toggle_normal_off">

            <android.support.design.widget.TabItem
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="Your First Text" />

            <android.support.design.widget.TabItem
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="Your Second Text" />

            <android.support.design.widget.TabItem
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="Your Third Text" />

            <android.support.design.widget.TabItem
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="Your Fourth Text" />

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