<p>i have Horizontal scrollview with 50 controll,as i am scroll it will display 50 gracefully.but at initially user not able to understand that this is scrollview and "I need to scroll for next item". so i have simply put two image at <strong>Right side</strong> and <strong>left side</strong> as you can see in image.now my problem is "i don't able to understand that how can i invisible left side arrow to visible &amp; invisible right side arrow".</p>
