I have implement simple one simple database application in which I have used scrollview.Its work fine.But scrollview is not bounce.
Is it possible to enable bounce in scrollview?
Thanks in advance.
Warning: I don't really know how to do this, I'm just thinking of how I would approach this...
Have you tried to put empty space on both ends of the view? That way it would look like the user is scrolling past the beginning/end. If there's a listener involved maybe you could test to see if the user is in the 0-10% range or the 90-100% range, and if so, "bounce" them back?\
Edit: I found this article: Support Bounce Property for Scrollview in Android

What is the easiest way to implement a screen slide in Nativescript like shown in Android Viewpager , but in a vertical direction ? Another example of this functionality would be the rss reader feedly where you can change rss feeds by swiping up/down.
The page should allow vertical scrolling to the top/bottom and then transition after a certain treshold.
I already encountered nativescript-slides, which can only do horizontally sliding.
So is there a "nativescript" way or do i have to implement it as native android/ios feature (for example by this) ? In either case a sample on how to integrate it in nativescript would be great.
Update
Recorded an example:
taken from this Repo with Android native code. The outstanding PR made changes to offer vertical scrolling in the list. But the repo seems to be outdated and a bit buggy.
I can provide more info later but there's a new plugin implementing the native controls for android and iOS for slides/carousel her https://github.com/alexrainman/nativescript-carousel-view and vertical swiping is on his radar, I think he might even be close to completing that.
To give an answer for anybody interested in above nested scrolling animation:
For Android I had to implement the native ReyclerView in Nativescript in favor of the NS buildin ListView. It is an optimized view structure which among other things allows nested (vertical) scrolling and can be used as replacement for an ordinary list.
Together with https://github.com/alexrainman/nativescript-carousel-view works like a charm!
Anyone that ends up here still looking for ways to achieve this.
I spent a lot of time trying to figure out a way to achieve this and tried to find ready plugins for this. Also tried to use the plugin from Alexrainman but eventually gave up since the plugin was not up to date with the current nativescript-version.
My solution:
I used radListView as a basis for this implementation and leveraged the methods and events on the radListView.
By using scrolled-event I gathered data for the use of the scrolling feature: scroll Speed and scroll direction. (These might be also taken from the event data, but since I did not find the event details from the Nativescript-documentation I gave up trying to guess where to find this data on the event-model).
Then I also saved the fixed height of one item on my list (The height I fixed to screenHeight-200).
With all this info, I managed to hook the event "ScrollDragEnded" and add logic that makes my list behave like a vertical slider. Moving on the list by method "scrollToIndex" and figuring out which index to scroll and when by leveraging all the data mentioned above.
This is the way I managed to make a pretty good vertical slide.
Good luck!
While going through a IOS app in my company, I saw the buttons set in a horizontal scroll view in a animated manner which looked really good. When asked the IOS developers they said it is a pre built in function available in xcode. I want to know whether it can be achieved in Android.
Details regarding the scroll view.
There are buttons when scrolled over revolves around. To be more precise it moves in the anti-clockwise direction but doesn't disappear from view.
Thanks in advance for the help.
May be this is what you want or it may help you

If my understanding is correct about your question, We have HorizontalScrollView to achieve that in android. You have to do your own animation while scroll. There is no in build animations while scrolling.
Please go through the following link.
Friends,
I am trying to develop an application which requires the below UI:
I know its not a feasible thing to run a ListView with-in ListView or with-in a ScrollView. So I'll like to know that Is there any other way to do this same thing ? as the UI has to be same as its running in its LIVE iOS App.
Thanks in advance.
Solution: Thanks guys for all of your answers, but as I told that the Expandable-ListView is not the option in my condition. So I have creating a dynamic layout in Java Class file using an amount of various Layouts & Widget's Array. It took a lot of practice but it covered the necessity.

check this it will help you
You don't really describe your problem in detail but from your indication of a blue bar at the left, I suppose that you want to have some sort of a secondary ScrollView inside the primary ListView; which itself has its one scrolling view. If so, then using an ExpdandableListView will not be the solution that you want.
Android has some difficulties managing a ScrollView inside another ScrollView but if this is what you want, then take a look at: ScrollView Inside ScrollView .
Be warned that these solutions are not perfect and that probably you will never achieve the same level of control for this type of thing on Android as you can have on iOS.
any idea how to implement something like the multiple desktops of the android?
I tried Gallery but it sucks I wansted something just like the desktop app
thanks
have you tried using <ScrollView>? I've never tried this so i dont know if its possible, but you might try sticking some layouts in a ScrollView and then listen for the scroll event. When the scroll event happens, you can then automatically scroll them from 1 view to the other so that they never end up half way between one or the other... if you try this, please post the code, i'd be interested in seeing how you do it...
In my case I used this tutorial :
http://developer.android.com/training/animation/screen-slide.html
It works very well but there is still the large background image sliding a bit at each page change to do.
Does anyone know how to achieve the "scroll past top" functionality that you see in some apps (like the HTC Sense email app for example) where when you scroll up to the top of the list and try to scroll up past that, it appears to pull down, and when you release it springs back up?
Take a look at this library: https://github.com/johannilsson/android-pulltorefresh. I think it implements the behavior you are looking for.
As far as I know, there is no built-in way to achieve this look with the default ListViews. Everyone who has done this implemented their own custom ListView widget that supports this functionality.
