RecyclerView Last Element Not Showing or getting cut off

Question

For those who believe this is a duplicate question I have already consulted the current solutions available on stack overflow Such as:

Last Item in recyclerview is cut off RecyclerView cutting off last item

However, no matter what I try I am unable to completely see, on in some cases see at all the last element. I have already checked my adapter to make sure the last item is being rendered. Here are the screenshots and xml. Thanks

This is the main layout that contains the recylerview that is inside a nested scrollview. Like I said I tried this solution by reading other threads.

Answer 1

this obviously is because of:

<View
    android:layout_width="match_parent"

    android:layout_height="25dp"

    android:background="@color/colorPrimary"
    android:id="@+id/view"
    tools:ignore="MissingConstraints"
    app:layout_constraintBottom_toBottomOf="parent"/>

have you ever had a closer look at the first one CardView ??

android:fillViewport="true" and tools:ignore="MissingConstraints" look suspicious;

replace these ConstraintLayout with LinearLayoutCompat , because these are linear layouts.

that NestedScrollView just would need weight 1.00 and height 0dp , to fill the space.
