I want to make a layout where you can swipe right and left to change the view content. However, I don't need to change the layout, I just need to change the texts in the TextViews and some visibility changes when swiping right or left. Do I need a ViewPager for that? And if yes, could you give me a link to some example.
I'm just a bit lost, I don't know what to google (and that's about the only problem google can't help you with:)
take a look at TextSwitcher or even a ViewSwitcher if you just want to change the text and you can check gestures out for the swipe action, if you decided to use ViewPager you can check the example provided above, or search google for more examples I am sure you will find lots.

I want to make a tab host in such a way that if I swipe left inside the tab host, a new tab will appear from the right and pushes the rest towards the left. I want the new tab that would appear will be able to position itself properly. I want smooth transition effect in swiping, so can anyone give me idea on how to achieve this effect? any sample codes? or any useful links containing tutorials? I googled this up and sadly no result showing what I want.
One way that I could think of is applying a scroll view there that could only be scrolled horizontally. But one problem I am worrying is the automatic positioning of the item. How can I achieve that?
Please help. Many Thanks!
it seems that you are looking for ViewPager and PagTabStrip Example.
google out on both topic and you will definitely find your ans.
Any ideas how we can make a menu like the one that Google has implemented in their YouTube app. I've read this, but that solution differs from the behaviour of the YouTube application. Does anyone know a real way to go about this?
I'm talking about this:
I believe that they use a HorizontalScroll in a RelativeLayout.
Image that the menu is always there to the left. You make that first.
Then you place a HorizontalScrollView on top of that and then put your main content in that.
Set your horizontal scrolling properties to only scroll a certain max. Then you wire up your menu button to slide your horizontalscrollview to the max you set and that should be it.
You can always check the source to the People Application in ICS. They do something very similar.
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.
I am looking to create a navigation or menu bar similar to the functionality of the one at the top of the Fox News app. I started to code this myself using a Gallery but I'm not sure how to hide the left and right arrows when they are not needed. I was also wandering if you would have to use images for the menu items or if you could just use TextView or buttons so I could change the text without having to modify an image. I have seen this type of navigation on several apps and I tried all types of searches trying to find code examples but I must not be using the correct name for this type of scrollable menu because I couldn't find anything. If anyone has an example or provide a link to an article I would greatly appreciate it.
Look into HorizontalScrollView. It is a Layout that will handle the smooth scrolling and is likely to be much less of a hassle to work with than Gallery for this operation (I just added one for a similar reason).
To handle the left/right, look into setOnTouchListener. I'm not sure if you can get the current scroll position without making a new child class of HorizontalScrollView to access protected methods. There may be other ways, however - I didn't need to add buttons so I didn't investigate.
In Android, I want to create a particular control which may require to set the location of a component by fixed coordinates.
This is what I want to do. These screenshot are taken from a swing application of mine. I want to clone the buttons on top and their behaviour, into an android application. Basically if there are too many buttons in the menubar, left and/or right arrows appear, and clicking on them will scroll horizontally to access the hidden buttons.
I need to be able to set the coordinates of an horizontal linear layout inside another one, and even to set negative coordinates in order to scroll on the right.
I'm doing this using a null layout in swing. Can I achieve this with Android ?
I'm not sure if an HorizontalScrollView can do this. Could someone point out a good tutorial or something related to what I'd like to do.
I think a HorizontalScrollView can achieve what you intend to do with your Menu Bar. You don't need these "scroll" Buttons, because a user can swipe the menu.
You can nest LinearLayouts together, however you want. if you want to control their flow try to apply margins to them. You can set fixed Coordinates in an AbsoluteLayout, too.
Consider using a gallery? If not gallery, then a child or cousin of it. As far as I know, there is no ViewParent that will allow what your are shooting for.
Hope that helped ~Aedon
