Android Question Automatic panel scroll up

[harinder]

I have a panel layout with a number of views loaded onto a scrollview2D panel. How can I effect the panel to shift up automatically by say 50dip on pressing a swiftbutton to make another hidden view below visible? Thanks

I used the normal scrollview(not scrollview2D)

scrollview.scrollposition=50dip

which works well.

I don't know if this could be for you:

Note that you can still use ScrollView2D, its properties:
HorizontalScrollPosition
VerticalScrollPosition

Hello LucasMs..that seems to be a class based on a swipe..im looking for a simple solution without adding a class module..

Note that you can still use ScrollView2D, its properties:
HorizontalScrollPosition
VerticalScrollPosition

How did I miss that? ?
A noob question though..what distinct advantage does sv2d have over the simple sv? Thanks

what distinct advantage does sv2d have over the simple sv? Thanks

The scroll direction, just one using ScrollView (vertical), both vertical and horizontal "simultaneously" (I mean that with ScrollView2D you cannot swipe horizontally perfectly nor vertically, choosing how when you want/need, it's a free movement.
Also, HorizontalScrollView exists too.

I am not able to implement horizontal sv on sv2D, though I have changed properties of both sv2d and loaded panel to 150%x in the Designer

Klaus, your post

scrollview2D.verticalscrollposition=scrollview2D.verticalscrollposition+50dip

Worked perfectly. Wondering why you deleted your post

Because I reread your post and misunderstood it and thought that the answer was wrong.
You could also use:
Scrollview2D.SmoothScrollTo(Scrollview2D.HorizontalScrollPosition, Scrollview2D.VerticalScrollPosition + 50dip)

But I am able to scroll only vertically despite sv2D as per my post #7

But I am able to scroll only vertically despite sv2D as per my post #7

It's simple...

ScrollView internal panel can be moved vertically only, by code or using your finger ?;
HorizontalScrollView internal panel... the same but horizontally;
ScrollView2D: by code, you can choose whether to move its internal panel hor or ver, using your finger you can move it "simultaneously" to both directions

 

[harinder]

My finger only giving vertical results

Scrollview2D.SmoothScrollTo(Scrollview2D.HorizontalScrollPosition, Scrollview2D.VerticalScrollPosition + 50dip)

Thanq Klaus..you are as helpful as ever

Why ?
If you set the Width of ScorllView2D.Width correctly you are able to scroll in both directions.
Then you can change the position with either
ScorllView2D.HorizontalScrollPosition
or
ScorllView2D.SmoothScrollTo(PosX, PosY)

Got it..Thanks
