Customize system combined bar /navigation bar for Android tablet (bottom) - android

I would like to override (add more buttons that would take me to several activities/fragments) to the system Navigation Bar on a tablet (according to this android ui-overview it is a "Combined bar" (for tablets)
Is there a way to do this?
I couldn't find a Navigation class in the android.app package, like ActionBar.
If adding buttons to the combined/navigation bar is not possible, I think there are several options, but I'd like to explore this first:
- use the action bar on top instead
- add a bottom bar above the navigation bar (not really fine, since it would be on top of the combined bar), like they are showing here:
Action Bar
Thanks a lot,
Cristian

Is there a way to do this?
No. The only thing you can add to the system bar are Notifications, which are not meant for this sort of navigation.

If you are referring to the section titled "Layout Considerations for Split Action Bars", that is referred to as a "split action bar", and can be enabled on an <activity> via android:uiOptions="splitActionBarWhenNarrow". However, that will only take effect for -small/-normal screens in portrait orientation. Your buttons will automatically be placed in the action bar at the top of the screen in other circumstances.

center align icons in titanium action bar for android

Is there any possible way to center align the action item icons that are shown in action bar of titanium app for android. I have searched a lot of places for this solution but had no luck. I want the action bar to look like the below image. Also tell me the way to not show app title in the action bar.
This is not a Titanium issue.
As you can read in Google's documentation, you won't be able to center anything in the ActionBar. Default (and expected) behaviour is to align action icons on the right (or left if reversed).
I don't recommend it, as it goes against Google's guidelines, but you will be able to center icons if you create a fake ActionBar:
- Remove native ActionBar from any window in your app
- Create a Titanium View that mimics the ActionBar
- Add icons and bind click events.
That's it, you are done.

Actionbar Push up relative to screen

I have achieved hiding and showing the actionbar on scroll however I have a few problems with it. 1.) when I click on a tab in my application that requires the action bar to be show then return to the screen where the action bar can be hidden, there is a white space that is the exact size of the action bar under the action bar. 2.) There is an annoying flicker sometimes when the action bar is being hidden or unhidden.
I have seen on many google applications and applications such as instagram where the action bar pushes up relative to the position on screen. I have searched for libraries or ideas on how to implement that technique but have not found any? Is there any way I can at least get rid of the actionbar flicker or is there a library where I can implement the actionbar push up on scroll in my application?

Put android tabs in center of action bar

I tried Android action bar with tabs. As you see in this picture:
(source: persiangig.com)
My action bar looks good in phones but in tablets it is not right, the tabs stick left. This picture shows what I mean, how can I put the tabs to center in tablets too?
(source: persiangig.com)
The tabs are aligned left because, in Android, the action bar is used for both navigation and Activity- or Fragment-specific actions. You don't have any in this screenshot, but menu actions that are added to the action bar will be aligned to the right.
If you must have your tabs centered for some reason, you'll have to write your own action bar. I would recommend against this, since it's a lot of work to intentionally go against user expectations. Instead, use Android's built-in action bar layout and design your app to accommodate it.

Android - Action Bar Style

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.

How to change layout on xlarge screens in ActionBarSherlock

I am building an app that uses ActionBarSherlock. I need to change it's layout so there is no padding arround tab icons. Now it looks like that:
| tab1 | tab2 | tab3 | t
But i want it like that:
|tab1|tab2|tab3|tab4|
I've manage to do so on normal size screens by changing that file:
library/res/values/abs__styles.xml
However on my Galaxy S3 still has padding, I tried changing paddings from:
library/res/values-xlarge/abs__dimens.xml
but no effect. I also tried to remove it but still no changes.
edit:
Just for information, I am using only icons but no text for top. All my icons are in drawable-hdpi, could that be a problem? I don't think so because they are not reseized or anything only paddings apper :S
that one is in values.
so I also tried comment out all lines with
<dimen name="abs__action_bar_icon_vertical_padding">0dip</dimen>
but no effect…
If your Galaxy S3 is running ICS or later, ABS will use the native action bar. Any changes you make to the library will have no effect.
Action Bar Sherlock library has some limitations in it.
Limitation 1 : Adjusting of Action menu items in action bar is not possible
Description :
You can have different action menu items in the action bar and also you can set the icons for that items in the action bar. But, adjusting padding between action items, Removing Toast for the action items in the action bar it is impossible. Because Action bar Sherlock uses native action bar. Only look and feel is similar to ICS, but behavior is restricted.
Limitation 2 : Activity Recreation
Description :
When Screen orientation changes, It will recreate activity which is in active. So User Interface will get updated and also it doesn't save the state of the application or activity..
Be Aware of Action Bar Sherlock
I wouldn't use ABS directly for Tab navigation. Consider using a Viewpager and ViewPagerIndicator, which is comatible with ABS (same author), and there you have a lot more control of the appearance . This way the user can also swip left-right to switch tabs.
Does this happen no matter what? I honestly haven't played too much with a native actionbar. What if you do something like an inset drawable? This would kind-of change how it's drawn and may shrink the icon, but might be a solution until you find something better.
