Android view, starts element from bottom overlap with header on small screens

I have a sample view, where on the top is logo + header divider + some description, and from the bottom starts: Button + some checkboxes, please see image below:

enter image description here

It looks good on current devices, but on old phones, when screen is small (5 inches for example) - elements overlap:

View looks like below:

</androidx.constraintlayout.widget.ConstraintLayout>

How should I set constraint between this two parts of the view, so they wont overlap on small screen? Add marginTop to the bottom section?

Solution

  • I found an answer, will post below, maybe it helps someone in the future:

    I copied all elements from Bottom section inside ScrollView:

      <ScrollView
        android:layout_width="match_parent"
        android:layout_height="0dp"
        app:layout_constraintTop_toBottomOf="@+id/header"
        app:layout_constraintBottom_toBottomOf="parent"
        android:fillViewport="true" >

        <androidx.constraintlayout.widget.ConstraintLayout
            android:layout_width="match_parent"
            android:layout_height="0dp" >

      <!-- all LinearLayout's from bottom section -->

      </androidx.constraintlayout.widget.ConstraintLayout>
    </ScrollView>
</androidx.constraintlayout.widget.ConstraintLayout>
