How To Implement A Swipable Tab Host In Android

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.

How to make a sidebar menu

I'm looking for a way to develop a menu which could be visible by sliding on the left of the current screen. One example is the mobile version of Firefox, when you slide on the left, you can access to the current tabs navigation, but the main page is still visible. It is called a sidebar I think :
EXAMPLE
One possible way to do that is to use ViewFlipper, I guess, but maybe is there an easier and more efficient possibility ? And I'm afraid that handling scrolling horizontally and vertically could be a bit difficult...
Thanks for any answers,
Maxetx.

Maybe this will give you an idea

You may try out SlidingMenu. There is example in lib.

Slideshow-like application

I'm supposed to make a simple android application, in fact it's almost as simple as a slideshow.
The good thing is that the content of each slide is very similar - some text and a photo. So I only have to do one layout and simply switch it's content on a slide motion or a button press.
I think it would be more appealing if I add some suitable animation - e.g. flipping the whole page.
Is there already a tool for this? If there's not than what's the best/simplest way to do this?

How to implement swipe pages [duplicate]

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.
https://github.com/commonsguy/cwac-viewswiper
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.

building an Android Status Bar like the New York Times app

The New York Times Android application has something like a notification bar at the top.
I suspect this is an included layout with a text view. The thing is that they managed to drag that title down in order to present the top news.
Can anyone give any insight on how to replicate this?
Edit:
Yes the drawer was the solution to my problem nevertheless i needed one as New York time and the default SlidingDrawer are meant to only go bottom to top... so i looked over on St Google and got a nice Custom Componente Sliding Drawer, get some difficult to make it work as i need it but you can follow the case in Layout positioning problem with Custom SlidingDrawer

I think what you're looking for is a Sliding Drawer.

edit:
the link I post is good for the documentation, but might not give a full idea of what is actually happening. A good place to find an example might be here:

They have most likely just used a TextView as you said. Moving it down can be done in multiple ways. The simplest is just to have another view or view group in top of it and initially set its visibility to gone, and then to visible when you want to show it.
Sorry, i misunderstood what you meant. Since the top element was so small, i simply thought you meant you wanted to expose a element on top of the other element. Ill up vote the other answer since this is most likely what you are after :)
