I’m trying to make a fragment that have a sort of form with lots of textViews, EditTexts and spinners, so i have to use a scrollView to see all the items.
For some reason the last item is not showing and i don’t understand why, I read lots of questions about this problem but no one works for me.
Can someone help me to solve this problem?
The xml:
<?xml version="1.0" encoding="utf-8"?>

/>-->
</androidx.constraintlayout.widget.ConstraintLayout>
</ScrollView>
</layout>
The last item (the button) are not showing when i use the app, i scroll and see all the items, except the button.
UPDATE using a useless item after the button with 60dp of weight allows me to scroll and see the button, i don’t like it but seems to be the only solution
UPDATE 2 I put the full xml

Answer
Have you tried making a dummy item ? In other words, add something that is fully transparent (invisible) but will take physical space after the button ? For example, a normal TextView with such parameters:
<TextView
android:layout_width="1dp"
android:layout_height="60dp"
android:text="-------"
android:textColor="@color/transparent" <!-- use color code #ff00000 -->
android:textSize="30sp"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="@id/yourlastbuttonIDhere"/>
Also, one thing to keep wary of, for best practices: When you’re setting constraints, for example here
app:layout_constraintTop_toBottomOf="@+id/assignmentSpinner"
You don’t use @+id/assignmentSpinner but rather @id/assignmentSpinner
(Remove the plus sign)
