Iv seen other post's that attempt to answer this but don't quite cover it. So hopefully somebody could clear this up.
I have an activity that displays a card, the idea is when you swipe right/left/up the card will move in that direction following the users finger movement the way ViewPager works for scrolling left right. What is the simplest way to implement this kind of animation ? Are there an Open Source libs that do this already ?
I currently have a slide_in/slide_out animation that is used in when calling replace in fragment manager but this applies the animation after the swipe action and not during
(EDIT) I could use a scroller and scroll the view but I wanted something a little "cooler" like swiping through a deck of cards one card at a time.
Thanks in advance

I'm trying to do some animation on my ViewPager. On my main View i have a ViewPager and two buttons. what I want to do is when I click on left button then view in viewPager is move to the left (off-screen) and next view fades in and the same way for right button but to right side. (something like Tinder app effect but simplest). I found a nice interface named ViewPager.PageTransformer but i can't figure out how to move view in way that I want.
Thanks for help :)
This repo has a handful of animations. If what you're looking for isn't present, at least you have a decent start.

You may want to see this. It shows a sample having 2 buttons and pages scrolls on click of these.

I'm trying to create a layout manager similar to ViewPager, but I'm not sure about what the best way to implement it is.
Basically I want my views to look like this:
From there I want to transition to other views when the user swipes from any of the numbered rectangles on the sides. So, say, if the user swipes from view number 3 and to the left, I would like to transition to the following view:
Ideally, I would like the transitions to be similar to how ViewPager works (i.e. I want the transition to interact with your finger so that the transition progresses back and forth when the user moves his finger from left to right).
It seems like I will need to implement my own version of ViewPager, I'm just not sure how to go about doing this. I only need to handle a small number of simple views so I can probably get away with caching all of my views for better performance.
I know how to implement the code to detect the swipes and where in the view the swipe started, but I don't know what the proper way to implement the view transitions is and how to handle the states of all the different views.
Any pointers are greatly appreciated!
Thanks in advance.
I want to implement the concept of "Slide to open" concept in my application. Basically, I am using an ImageView. If the user slide it to a specific direction (to the right for example), the next activity is started. I do not know how to implement this in Android, I have searched in lots of place but found nothing.
Any clues ?
What I came into :
No I do not think that the use of ViewPager or HorizontalScrollView is appropriate in this case.
I don't know if the concept of Drag And Drop helps (how to imply a drag in a specific direction ? How to let the ImageView return to its initial location if the drag ends midway ? ...)
Use frame layout and put a ImageView in it. Then add touchEvents to Imageview. update imagViews Layout parameters at ON_MOVE event.This is the basic idea of slide and drag stuff in android.Good luck.
you may use View.Animation for moving back the slider to start position again ON_UP event
you can move view only in x axis by only changing the views :
LayoutParams.leftMargin=event.getRawX();
(always set the gravity to NO_GRAVITY)
If you want to implement smth like "slide to unlock" you can implement drag and drop and forbid moving by Y axis for example. Also you can check image position and analys if this shift is enough to open\unlock, and if not - simple move this image back.
I've made an activity that looks a lot like the level select screen from angry birds: there is a grid of button, and you can scroll through pages of them by swiping right or left.
I built it by creating a layout of the buttons, and then adding those layout to a Gallery view.
The problem is the animation is jerky, even if you swipe extra slowly, the content jumps ahead. Even when you fling the gallery page, it skips and jumps along its way to its destination.
I am wondering how to fix this: Maybe the complex layout it making it non responsive during the inflate?
Do you know how to fix this, or of a good way to do a workaround using some other approach that will let me have 3 or more screens smoothly swiping from page to page?
You should be using ViewPager. This is available in android support packages. Gallery Widget will not be smooth if you add components into it which has a lot of touch actions.

I have searched a lot but I couldn't find an answer.
I want to implement something like in Go Launcher. When you drag an icon in app drawer and move it out of container top or bottom bound, the list begins to scroll.
So far, I have tried following things:
Dispatch touch events to simulate scrolling - impossible while touching the screen
Use smoothScrollBy() method - almost there, but it scrolls only screen height distance
Use scrollBy() - it moves only the container and leaves blank space. I would put there some rows if only I could be able to reuse views that went off the screen.
I need the ListView to scroll SMOOTHLY.
So here goes ma question. Anybody knows how can it be done? I'll put a gratitude in About section of my app to person who will help me:)
using listview and try scrollToPosition（），or smoothscrollBy（）
