Using both list navigation and tabs with ActionBarSherlock? - android

I'm looking through the ActionBarSherlock samples demo, and I see that the List Navigation and the Tab Navigation both make use of the ActionBar's setNavigationMode method. This tells me that you can only have one or the other. If I want the user to have list navigation to move around between activities but I want some activities to have tabs, is there a different way to add tabs than via navigation mode? Is it against ActionBar design guidelines to use both? I don't look at tabs and consider this to be a navigation feature, so I find it odd that you get one or the other.

This tells me that you can only have one or the other
Correct. Bear in mind that with action bar tabs, Android will convert you to list navigation, on its own, in certain configurations, whether you like it or not.

You can use a ViewPager with PagerTabStrip or the tab flavor of ViewPagerIndicator.
Or, you can go retro and use TabHost and TabWidget.
Is it against ActionBar design guidelines to use both?
The design guidelines refer to them as separate options for "View Controls". More importantly, given the automatic conversion of tab navigation to list navigation, it would be seriously confusing for the action bar to have two Spinners' worth of navigation choices.

Android Airbnb like Tabs

I am trying to figure out how airbnb has implemented its Tab Bar, it either seems they have hidden their actionbar and everything has been shifted onto a tab bar but then the right most user icon opens the navigation drawer which should be ideally on actionbar, Or everything is on action bar itself but then how can those 3 tabs/icons on left be implemented on actionbar. (Kindly refer attached image)
Can somebody put some light on how this can be implemented. How to go about it? Also are those 3 icons fragments or separate activities?
Here, is a library which makes your life simpler to implement TabBarView for actionbar tabs.

This should give you insight about how to use it for your app.

Slidable tab navigation depending on the screen size

I am looking for a Tab navigation UI component that would work similarly to the SlidingPaneLayout, i.e. would show as many tabs as possible and make the tabs slidable left/right when the tabs wouldn't fit on the screen (in my case its tablets vs smartphones case). An example of it would be Slideable top navigation UI pattern.
Is there any library I could use to implement such component in my app?
Action bar tabs and ViewPager are the one's you are looking for. These are in built feature of Android, Easy to access and backward compatible to earlier versions as well.
ActionBar tabs is the one that will give you the tab like feature.
ViewPager on the other hand will provide the functionality of swipe.
Here is a step by step example on both.

Moving the ActionBarTabs

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.

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.

How can I allow horizontal tab navigation (swipe views) with action bar navigation tabs?

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.

Which sub navigation pattern on a tabbed pageable ActionBar main navigation for Android?

Does anyone of you know of a sub navigation pattern in Android that uses a tabbed ActionBar navigation with pageable Fragments for its main navigation? (ViewPager)
I have looked at Spinners in the ActionBar which could work quite well if it wouldn't take ages to get the submenu rendered in the ActionBar while swiping from one tab to the next. (in the end you have jumping action items which look pretty ugly)
The other approach would include a segmented control widget which is known from the iOS platform. (like the TED application has it at the moment)
But what would be the Android way of doing it?
Why can't you try menu's for different tabs? I dont know whether it helps or not.Surf google for creating menus for each tab.
