I have 2 screens black with scroll View in it and then I would like to change these screen with a swipe. I am using Android Studio and want to have a simple example so that i could change all the screens from one to other using swipe view. I hope the best example from the all the best developers on opposite side.
Thanks.
View Pager will be the best suited component. There are a lot of samples available in the net.

I'm planning to implement tutorial screen for Android app.
My plan is that tutorial screen looks like:
There are several screens and you can swipe between than. Every view has custom design. There are dots which represents every screen, and show what page are you watching now. I need good-looking transition with adequate animations.
This screen will be full screen activity.
I have found several Image Galery, but I don't want to slide between images, I need to slide between views.
I do not need exactly code for this. I need instruction in which way this can be done, and what elements I need to use in order to achieve targeted design.
Thanks in advance.
You'll want to use ViewPager in conjunction with Fragments, the instructions are on Android developer's website.
I need to design introduction walk-through screens when my app launches. It can be done by simple ViewPager or horizontal scroll view (?) but the additional requirements which are hindering me from using these are
A lot of animations on each screen
Animations will be bound to scroll position (i.e., current stage on an animation will be determined by how much user has scrolled, and it should roll back animation if user scrolls back without finish gesture)
Some items need to animate across different screens (e.g., There is a box on first screen, when user scrolls to the next screen, the box becomes larger without moving and a graph (a part of second screen) also comes into display under it)
I dont know if I explained the scenario well enough so please ask for clarification in comments. I need just a direction to control/approach/library.
Thanks
I'd recommend this library : ShowCase
In this way, you can make interactive tutorial and walkthrough your app.
You can also take this library and add some functionality.
Use viewpager, for each fragment you can use different animation inside that fragment, each fragment is independent from other views/fragments
You can use horizontal scroll view but it will take extra time and difficult to code
Seems like a ViewPager has everything you need.
I'd like to make a view in my Android app that flips between multiple views on a swipe/fling. I'd like it to behave more or less like the Android Launcher behaves when flipping between views. In particular,
It should flip views on swipe.
Generally a swipe will flip between one view and the next. It should not fling across all of the views.
If you swipe slowly, you should see the views dragging as you're swiping, eg. the way the Launcher does it.
I tried using a ViewFlipper with a GestureOverlayView as per Romain Guy's blog post here, but there's no indicator to the user as they're swiping. This makes discoverability difficult, which is presumably why Launcher does it the way they do.
I tried using a Gallery object, but when I swipe from left to right, there's a certain amount of momentum that flings the users through all the views rather than just taking them to the next view.
Is there a good way to accomplish what I'm trying to do?
I know this is an old question but ViewPager is created for this exact same purpose. ViewPager is part of android compatibility package and more can be found at http://android-developers.blogspot.com/2011/08/horizontal-view-swiping-with-viewpager.html
Take a look at HorizontalPager. It's actually based on RealViewSwitcher, which in turn is based on the Android homescreen's code, and supports snap-to paging with drag feedback, as well as nested vertically-scrolling subviews. Gesture support for fast swipes isn't all it should be, but this may get you part of the way there (and I'd welcome contributions back).
EDIT: As of 2012 you're much better off using Google's ViewPager - it's in the compat library.
Check out SwipeView within this project https://github.com/fry15/uk.co.jasonfry.android.tools It does exactly what you want it to do and is super simple to implement.
#CommonsGuy extended ViewFlipper to do it.

Ihaven't used this one yet so im not sure if it moves with your finger like the launcher if not your going to have to make an OnTochListener to do it for you in me.ACTION_MOVE you will update the view to change its position. I'll post some sample code when I get home if you don't get another answer.
Is it possible to change the size of the tabs displayed in a TabActivity? I'm currently only putting text in my tabs and I'd really like to minimize the size as much as possible.
Also, is there a way to use icons for my activity that aren't 48x48? I'd like to do something more rectangular as opposed to square. I just want to use my screen real-estate the best I can :)
How is the YouTube app doing this? (See screenshot, and yes I know that the YouTube app isn't open source)
It seems that they're also making it possible to scroll left and right for more tabs. Any ideas on how they're doing this?
Yest you can do all that by creating your own custom view for tab widget, it is quite simple to do. this tutorial will do the trick

In the android home screen, we have the ability to slide the screen left and right and display multiple pages. Each of these pages has a different set of icons. In the Mac world these would be called "spaces". What are they called in the Android world?
More importantly is there a standard control that can be used to achieve this effect?
There is no such control to achieve this. Once I was digging through the Launcher's source code and this effect is done by creating few LinearLayouts and placing them side by side in the code. Sliding through the "spaces" is done by handlig touch events. Also the grid that handles widgets is created using aviable API.
Unfortunately, there isn't a standard control for that sliding effect.
This is another question about the effect which also contains a few pointers about implementing it.
