I have scrolled, tell me, please, how to make it clear borders in the form of lines along the four edges?

<ScrollView android:id="@+id/scroll" android:layout_width="match_parent" android:layout_height="0dp" android:layout_marginTop="8dp" android:layout_marginBottom="16dp" android:visibility="visible" app:layout_constraintBottom_toTopOf="@+id/btnAdd" app:layout_constraintEnd_toEndOf="parent" app:layout_constraintHorizontal_bias="0.0" app:layout_constraintStart_toStartOf="parent" app:layout_constraintTop_toBottomOf="@+id/textView4" app:layout_constraintVertical_bias="1.0"> <android.support.constraint.ConstraintLayout android:id="@+id/linearLayout" android:layout_width="match_parent" android:layout_height="match_parent"> </android.support.constraint.ConstraintLayout> </ScrollView>
