Question

I am working on an android app, and now I am putting a simple form in the dialog box this form I wanna used for address info, and it has multi-element.

the scrollView is existing and I can scroll up and down but I can't scroll down to reach for the last item in my layout.

Just replace ScrollView with NestedScrollView, as you used Spinner inside the ScrollView which has own scroll view.

Here is changed Xml Code

<?xml version="1.0" encoding="utf-8"?>

android:layout_height="wrap_content"
