you have added view in relativelayout, hence should specify have positioned. since have not specified tablayout tablayout overlapping toolbar. add android:layout_below="@id/toolbar" in tablayout.

<android.support.design.widget.tablayout     android:id="@+id/tabs"     android:layout_below="@id/toolbar"     android:layout_width="match_parent"     android:layout_height="48dip"     android:background="@drawable/background_tabs" />
