I have an activity with three fragments. Fragment A has 1 item in actionbar. Fragment B has 4 items in actionbar, and Fragment C has 1. So, I want to have split actionbar when I change to fragment B, but I don't want split action bar in A-C fragments, because there is no reason to fill de bottom of the screen with a bar only for one item.
Can I change actionbar mode when I change between fragments?
Not sure if this can be done using Fragments as ActionBar is associated with the Activity. However, I tried what you are looking for with two activities and it worked.
Add the action bar in onCreateOptionsMenu in both the activities and then add
getWindow().setUiOptions(ActivityInfo.UIOPTION_SPLIT_ACTION_BAR_WHEN_NARROW);
right before onCreate method of the activity in which you want the split action bar to appear. Thats it. Simple isn't it. :)
You can also hide and show it using getActionBar.hide() and getActionBar.show() methods respectively.
(The only thing I missed is checking this with support libraries. Will try and update you on that as well)
Let me know if this helps you in some way. Happy coding :)

I've set up a ViewPager in my App with tabs, but I need to position the tabs underneath a button so the layout would be
TitleBar
Button to search activities on a day
Tabs of each day there are activities
Is that kind of layout possible to do using Tabs or will I need a different approach to solve this?
The way the activity is running is theres a main activity, and the layout is just the button and a FrameLayout, and the the list (where the ViewPager is) is set up in a fragment and the fragment is loaded into the FrameLayout. I don't know if this is the best method for this so if not please add your recommendations of a better method I could use.
EDIT: If I could get it so all the tabs were at the bottom of the screen this would also be fine.
Is that kind of layout possible to do using Tabs
Not with action bar tabs. Not only can you not control where the tabs go, you cannot even control if there will be tabs versus a drop-down list.
will I need a different approach to solve this?
You are welcome to use some other tab solution (ViewPager with a tabbed indicator, FragmentTabHost, etc.) where you have more control.
Note that your proposed design does not adhere to Android design aesthetics. Most apps would not have "Button to search activities on a day", but instead a search action bar item, or perhaps a SearchView in the action bar.
If I could get it so all the tabs were at the bottom of the screen this would also be fine.
This is completely against the Android design guidelines. Don't use bottom tab bars on Android.
I'm doing my project which is based on action bar tabs....I encountered with a problem.....it is
1.My requirement is i need to place 4 tabs at the bottom of the screen whenever I'm clicking the tab the view should be change.
2.So at first i choose tabs for this but i got to know that tabs are deprecated.
3.So i have chosen action bar with tabs and for view i have chosen fragments .
4.Still now every thing is fine and perfect.
5.But what i need is i need to place those tabs at the bottom.
6.And exactly i need tab view i tried split action bar for this but it doesn't appear to the tab view.
7.So dear developers can you please help me for this
I think i have given valid information .If you feel it as insufficient please let me know
While ActionBar has a manifest attribute: android:uiOptions="splitActionBarWhenNarrow" this won't work always, not for tabs.
The other option you have is to use a ViewPager with a FragmentStatePagerAdapter. This will make swipe-able pages from fragment. Now you can include PagerTabStrip or PagerTitleStrip in Activity layout, inside <ViewPager> tag, at top or at bottom by using android:layout-gravity attribute on it.
This will show and switch to fragment/page titles.
I've just used ActionBar Sherlock to implement the android action bar on pre 3.0 android devices. I'm having one issue when I'm using tab navigation though.
Currently the action bar is devided in two rows at the top of the screen. The first row contains the app icon and app title, while the second row contains my navigation tabs. I tried to remove the top bar with actionBar.setDisplayOptions(0);, but now i still have two rows, but the top row is empty. How can I remove this top row?
Thanks!
I recognize this was posted about a month ago, but I think I can lend a hand. Try running these three methods just after constructing your action bar:
bar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
bar.setDisplayShowTitleEnabled(false);
bar.setDisplayShowHomeEnabled(false);
The first just sets the AB to tabs, which I assume you've already done. The second disables the String title up top (I should note that it appears when the app first launches, but then disappears very quickly), and the third shuts off the icon with the same functionality as the previous method. I actually had the same thing you're dealing with occur in my app, but once I ran both of those methods, the extra, and blank, top-most bar disappeared.
In addition to the accepted answer, Just remove onCreateOptionsMenu and onOptionsItemSelected to get clean tab view without having any empty action bar.
well, I have my Android app that have 4 main options. For that I created a TabActivity with this options.
Problem, when I enter to one of this, a activity is called. Cool. Imagine I have a list and when I click on one row I open other activity, the tab will disappear what is correct. But I want this tabBar always.
how can I achieve this?
if I copy/page this tab in every activity I need it it will load the ones that are attached to the tab and wont show the one that I opened before, right?
You should try with FragmentActivity. There is a addTab function to add tabs to action bar, in which you set tabs. With fragments and action bar what you want to do is possible
Take a look at Action Bar Sherlock that includes actionbar compatibiliy with tabs and more for non Honeycomb versions of Android.
I'm building an application that requires Tabs, which are now deprecated. The dev guide says to use Fragments to replace the tabs instead. However, my application needs to have fragments within each tab, which means fragments inside fragments, which isn't allowed. Does anyone know of a possible work around for this?
While the action bar support for tabs is designed to make it easy for the contents of a tab to be a fragment, that is not strictly required. You could use ViewFlipper, repeated calls to setContentView(), or something to arrange to change other stuff when the action bar tab is selected.
Prior to the native action bar (Android 1.x/2.x), either stick with classic tabs, or use something like Action Bar Sherlock to get an action bar and tabs.
I fake tabs by having a "tabs" fragment across the top that contains multiple toggle buttons. Below that I have a merge view containing a separate fragment for each tab.
I respond to taps on a toggle button by toggling the other buttons "off", showing the fragment for that "tab", and hiding the others.
its little late , but yes you can :) here's an example
but for fragment inside fragment inside tab isn't an android native way, you have to start a new fragmentActivity if you want to show detail of fragment. you can but is not an android way !
