xml won't build, how other possible way

I could not build my project due to this xml code, but cannot figure out where exactly lays the problem. I first used scrollView, I did delete it, and used ListView instead. Since then could not run my project.
the error I am getting is this:

Your root element specifies two aliases for the same namespace:
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:anddroid="http://schemas.android.com/apk/res/android"
Then in the ListView with an ID of #+id/lst_view you specify layout_height and layout_width twice, once with each alias:
anddroid:layout_width="409dp"
android:layout_width="396dp"
anddroid:layout_height="328dp"
android:layout_height="244dp"
That means you're specifying the same namespace-qualified attribute twice for each of width and height. That's not allowed.
Just remove the anddroid typo-alias, and remove the two attributes using it.

What does it possibly mean? what i have done wrong?
I'm really worried about this. i have go through my code many time but didn't find the error

The second-to-last line of your file has
</>
which causes your XML file to be not well-formed. Change it to
</androidx.constraintlayout.widget.ConstraintLayout>
to properly close a previous opening tag of the same name.

Android: Cut off constraint layout

When adding a constraint layout within another constraint layout the inner one gets cut off.
I already tried changing the constraint top of view but that didn't change anything. Anyone knows why this is happening?
I also tried it out with different layouts ( the cyan one is the culprit ) which all had the same effect.

It seems that you have an unnecessary android:layout_marginBottom="256dp" in your nested constraint layout.

Hi please add fillViewport as true in scrollview.
<ScrollView

Is it possible to put an image over all other layout elements (Buttons...)

I have a login screen with a Login button... I also have a ViewPager with some images. When I slide the ViewPager the image covers some login elements, but not all.
Right now I use the android:background = "myImage"
I also tried to use android:foreground = "myImage", but somehow it does not cover two of my buttons.
