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 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 :)
How can I allow horizontal tab navigation (swipe views) if I'm using action bar navigation tabs?
Is there anything special I have to do to get this to work with ActionBarSherlock?
The code-generated stuff for a "Tabs+Swipe" activity (from BlankActivity in the new activity wizard in Eclipse) has code for this. Basically, your tabs tie into a ViewPager, calling setCurrentItem() to change the page, rather than running their own FragmentTransaction or otherwise affecting the UI. The ViewPager handles the horizontal swiping, and you populate those pages using some form of PagerAdapter (one is code generated for you). See this very related question and answer for more.
Is there anything special I have to do to get this to work with ActionBarSherlock?
Other than standard stuff for using ActionBarSherlock, nothing out of the ordinary should be required. ViewPager is in the Android Support package, which ActionBarSherlock also needs, so you will have that already in your project.
Note, though, that action bar tabs only sometimes show up as tabs. In some screen sizes and orientations, they are automatically converted into a drop-down list (per "list navigation" with the action bar instead of "tab navigation"). If you want to use tabs all of the time, rather than using action bar tabs with ViewPager, use PagerTabStrip (from the Android Support package) or a suitable indicator from ViewPagerIndicator instead.
For my application , I'm planning to have a design as this:
http://img811.imageshack.us/img811/7045/problemel.png
-Design needs to have a title bar which is indeed the action bar in android. To overcome the compatibility issues, I used the sherlock action bar which is said to support older versions that dont have action bars. I havent tested yet for the older devices however.
-As far as I know, for navigation , we could rather use tabbed or dropdown list methods. I want to have constant tabs for every page in my app to stand below the page. This reflects the tabbed action bar, however I want it below not just under the action bar. I don't know how but youtube application somehow has it in the middle of the screen (if it's not a custom view). So how do we have tabs positioned in the bottom of the page?
-Also I want to have another menu, whose items depend on the page it's on. But the apperance will be the same for every page. In the picture on the left this menu has buttons as "Bt 1" ,"Bt 2". I dont want to repeat the same xml for every activity page, but I'm not sure how to achieve it without repeating. If the action bar allowed using both navigation tabs and the drop down list, I could put the items of this menu in the dropdown list just as the picture on the right (onto the gray button). But I guess it does not?!
Therefore I have to repeat the menu xml code in every page or is there another smart way?
Any advice will be appreciated.
This can be achieved not with tabs but by adding items to a linear_layout with a gravity of bottom but it is a bad practice as #D_Steve595 stated and should be avoided in android designs.
actionBar.setHomeButtonEnabled(false);
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
actionBar.setDisplayShowTitleEnabled(false);
actionBar.setDisplayShowHomeEnabled(false);
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.
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 !
