• If you have scroll element on your Android Intent like HorizontalScrollView, TextView or elements inside ScrollView, and you do not want the ScrollBar to be not visible when the element is scrolled just add the below line to your element XML tag.

android:scrollbars="none"

You can also achieve this programatically using methods setVerticalScrollBarEnabled(false) and setHorizontalScrollBarEnabled(false) for your view.

• onCreate: add source directly (Hide)

vscroll1.setVerticalScrollBarEnabled(false);
vscroll1.setHorizontalScrollBarEnabled(false);

• onCreate: add source directly (Show)

vscroll1.setVerticalScrollBarEnabled(true);
vscroll1.setHorizontalScrollBarEnabled(true);
