                android:layout_height="match_parent"
                android:layout_weight="1"
                android:textSize="16sp"
                />
            <Button
                android:id="@+id/btn_popup"
                android:layout_width="20dp"
                android:layout_height="20dp"
                android:background="@drawable/ic_more_vert"
                android:backgroundTint="#000000"
                android:layout_gravity="end"
                style="@style/Base.Widget.AppCompat.Button.Borderless"
                />
        </LinearLayout>
