              android:layout_height="54dp"
              android:layout_alignParentTop="true"
              android:layout_alignParentStart="true"
              android:layout_marginStart="20dp"
              android:layout_marginTop="20dp"&gt;
  
              &lt;ImageView
                  android:id="@+id/button_menu"
                  android:layout_width="44dp"
                  android:layout_height="44dp"
                  android:layout_alignParentTop="true"
                  android:layout_alignParentStart="true"
