EditText not editable after ListView is put into LinearLayout

Question

I'm building a simple To-Do app. I've put EditText and then created LinearLayout above. But after I put ListView into LinearLayout, EditText stops working meaning that I can't press on the plain text and type. If I delete ListView, EditText is working.

Any suggestions? What is not right here?

I'm quite new to Android Development. Thanks in advance!

I've got Constraint Layout in which I put EditText. In this same layout I put LinearLayout, in which I put ListView, and after that action EditText stops being editable, and I have no idea why.

I also want to add that I did all that using the full YouTube tutorial on that dated year 2019. So it shouldn't be an issue, should it?

UPD: The problem has been fixed changing ListView to androidx.recyclerview.widget.RecyclerView, but I still want to know why the problem was there in the first place.
