如何使textview填充线性布局的高度？

Question

Ok, I've been spending hours trying to solve this or even find a solution online and so far nothing has worked. How can I make the TextView "content_note" fill the available space in this LinearLayout?

Answer 1

The solution is to use android:fillViewport="true" on the ScrollView

and change this LinearLayout android:id="@+id/note_view" child control height from wrap_content to fill_parent .
