I have a ListView in my app and I want to show contextual action bar on a long press gesture like in design best practices for ICS
http://developer.android.com/design/patterns/selection.html

so, I think here's a good tutoiral:

If I want a customized action bar, should I implement the customization on the action bar or should I just use a custom view instead of an action bar. Navigation bar in iOS has a specific animation but as far as I understand, action bar in Android does not have anything speacial associated with it. So would it be more flexible and easier to implement it as just a view?
Once in a while I was thinking like this created a app with custom view as a action bar but when we want to use custom view we have to declare everytime in every activity which may cost more time .
Pros : You can create your action bar as per your wish can animate,change design,change UI etc.
Cons : cost more time on development .
It is possible to have a split Action Bar only in Action Mode?
My application have only the top action bar, but it's Contextual Action Bar needs to be splitted in two (top/bottom).
I found this:
The contextual action bar is not necessarily associated with the action bar. They operate independently, even though the contextual action bar visually overtakes the action bar position.
on http://developer.android.com/guide/topics/ui/menus.html#CAB. So i think it's possible, but how?
I'm pretty confident it's not possible - and even if it is - i would cringe to see the hack.
The cab is a crafty beast that offers a lot of convenience out of the box but doesn't like to be tampered with.
The platform takes care of you fantastically by placing a CAB at the bottom if required or collapsing items , but as far as UI designs go, you should avoid relying on the bottom bar.

I want to show Action Bar like below.
I have already used this library clickhere
But it takes only two icons on Action Bar. If I add four items, then last two are shown me like menu. I want all in Action bar same as image above.
Is it possible? if yes, then HOW? Can I change Action Bar color or its default style available in Device?
Thanks in Advance.
I recommend you use this:
http://jgilfelt.github.com/android-actionbarstylegenerator/
to style your ActionBar.
If you want all the 4 icons to be there, just add this attribute to all the menu items:
android:showAsAction="always"
hello try this library
it sure help you And you may have to add you own logic to handle this in below 2.3 Android OS and above 3.0 Android OS.
there is many demo sample available like below :
There is no way you can be sure of the number of icons displayed in the action bar. There is a large varierty of Android devices out there and they all have different screen sizes. That's why you have to prioritize the actions available in a menu : the most important will be displayed as actions in the action bars and the others will be displayed in the "menu" : the action overflow.
You should think of actions in a functional way, not a graphical way.
With ref to Image that you attached you should decide which design pattern you want to use in your application, there are many UI patterns available for mobiles, tablets. The image you attached looks like Side Navigation UI pattern. It's better you decide which UI pattern perfect for your app.. then start implementing it with custom action bar libs (if you want action bar in less than Android 3.0 ver) or any other.
I'm looking for a way to implement a drop down on a contextual action bar, that shows the number of items selected, then has a drop down for either Select all or Deselect all. The standard Gallery app has this.
Is the only way to do it, to create a custom view to replace the title, or is there a simpler way? If you need to call
setCustomView
and replace the title, what's the best way of doing this. Would a Popup Menu be suitable. I want it to follow the same style as the contextual action bar for things like touch feedback, colours and the small arrow indicating their are more options.
Thanks.
Is there a way to center Action Items on the Action Bar?
Something like this pulse.
No. The ActionBar doesn't support images in the middle, and I assume Pulse isn't using the real ActionBar.
The ActionBar is a great user interface component - work WITH IT, not against it.
