You can use Sliding Menu Library to give such effect...
You can get the code from here.
You can also refer this link.

It's possible, and you can implement it using the Navigation Drawer which comes with android support library.

You must check out the Ribbon Menu
1) What's the Purpose
Ease of Access: Allow easy access to a menu that slides in and out
Ease of Implementation: Update the same screen using minimal amount of code
Independency: Does not require support libraries such as ActionBarSherlock
Customization: Easy to change colors and menus
2)What's New
Changed the sliding animation to match Facebook and Google+ apps
Added standard ActionBar (you can chose to use ActionBarSherlock)
Used menuitem to open the Menu
Added ability to update ListView on main Activity
Added 2 ListViews to the Menu, similiar to Facebook and Google+ apps
Added a AutoCompleteTextView and a Button as well to show examples of implemenation
Added method to allow users to hit the 'back button' to hide the menu when it is open
Allows users to interact with background(main ListView) and the menu at the same time unlike the Facebook and Google+ apps!
OR
You can also try out with Sliding Menu

You have to add one library file slider.jar into your project and follow this example for the same :

Expandable Tab menu

everybody
Currently i am working on Android Native App .I wish to create a expandable tab without any HTML or JavasScript file. My App is totally native App.
I wish to show something like above picture.

You can try background image for Button/image.
Set one background-1 for default, use another for hover/ click/ select effect.

Create a view something similar to pinterest

I am working on an application related to news feeds where I need to GUI design like Pinterest application as in attachment picture image ,There are thee things (menus) at top like Search , Pinterest and Profile ,I want the same that should be change by swapping and click , User can switch among (search,Pinterest and profile ) top menu by click and swapping .Anyone can guide how I can do it ? I try tab view but unable to add swapping , anyone can guide me better way ?

For such a layout, I would recommend ViewPagerIndicator. Make sure to download the demo application and look at the code of the swipable tabs implementation. That may be exactly what you're looking for.
For an easy customization of the tabs in there, you'll find the Android Asset Studio helpful.

How to design a iPhone like menu/button in android at the bottom?

I have googled this, most of the solutions are using:
1.TabHost with customized style which would cover the separate line between each tab to archive the requirement.
2.On the android developers website, there is a article is using Merge layout to put 2 buttons on top of the background image kind of archive what I want.(http://developer.android.com/resources/articles/layout-tricks-merge.html)
3.What about using button but style the looking like the example below? I don't need the selection, cause each item in the menu will be a button, which takes the user to another page.
I am wondering is there any other solutions apart from these two?
This is something want:
I don't need the menu likes a tab which has selected and unselected, they are better like a button always displaying in certain screen(activity).
Thank you.

You can use simple buttons, and provide any custom background for it. For such simple form as on your screenshot look for this link.
But #Janne write right thing - you should be very careful with transplanting controls from another platforms.
