Action bar navigation modes are deprecated in Android L

Question

Taking a look at the API diff report for the Android  L  preview  I see that all methods related to navigation modes in the ActionBar class  such as setNavigationMode    addTab    selectTab     amp c   are now deprecated   The documentation explains      Action bar navigation modes are deprecated and not supported by inline   toolbar action bars  Consider using other common navigation patterns   instead    What is the supposed replacement   Also  is  inline toolbar action bars  a new concept  I don t think I ve heard of it before

I think a suitable replacement for when you have three to five screens of equal importance is the BottomNavigationActivity,this can be used to switch fragments.

You will notice a wizard exists for this in Android Studio, take care however as Android Studio has a tendency to produce overly complex boiler plate code.

I found these tutorials helpful while putting together an action bar  now the  tool bar  - argh  that supports sliding tabs with Material Design    https   www youtube com watch v Fl0xMuo10yA  http   www exoguru com android material-design navigation android-sliding-tabs-with-material-design html  You sort of have to synthesize these resources to match your particular situation  For example  you may not want to manually create the tabs in the same style that the exoguru com tutorial did

Now that the Android 5 0 docs are available  we have the official documentation for the Toolbar widget      A standard toolbar for use within application content       A Toolbar is a generalization of action bars for use within   application layouts  While an action bar is traditionally part of an   Activity s opaque window decor controlled by the framework  a Toolbar   may be placed at any arbitrary level of nesting within a view   hierarchy    A Toolbar widget can also be used to replace the action bar      An application may choose to designate a Toolbar as the action bar for   an Activity using the setActionBar   method    The deprecation of tabs in the action bar is most probably due to this  since toolbars cannot contain tab themselves   Also  it s available for previous Android verions via the appcompat library  See this post by Chris Banes for more information  An excerpt      Android 5 0 introduces a new Toolbar widget  This is a generalization   of the ActionBar pattern but gives you much more control and   flexibility in using it  Toolbar is a view in your hierarchy just like   any other  making it easier to interleave with the rest of your views    animate  react to scroll events

It seems like they added a new Class named android widget Toolbar that extends ViewGroup  Also they added a new method setActionBar Toolbar  in Activity  I haven t tested it yet  but it looks like you can wrap all kinds of TabWidgets  Spinners or custom views into a Toolbar and use it as your Actionbar

FragmentTabHost is also an option   This code is from Android developer s site          This demonstrates how you can implement switching between the tabs of a    TabHost through fragments  using FragmentTabHost      public class FragmentTabs extends FragmentActivity       private FragmentTabHost mTabHost        Override     protected void onCreate Bundle savedInstanceState        super onCreate savedInstanceState        setContentView R layout fragment tabs       mTabHost    FragmentTabHost findViewById android R id tabhost       mTabHost setup this  getSupportFragmentManager    R id realtabcontent        mTabHost addTab mTabHost newTabSpec  simple   setIndicator  Simple                FragmentStackSupport CountingFragment class  null       mTabHost addTab mTabHost newTabSpec  contacts   setIndicator  Contacts                LoaderCursorSupport CursorLoaderListFragment class  null       mTabHost addTab mTabHost newTabSpec  custom   setIndicator  Custom                LoaderCustomSupport AppListFragment class  null       mTabHost addTab mTabHost newTabSpec  throttle   setIndicator  Throttle                LoaderThrottleSupport ThrottledLoaderListFragment class  null

The new Toolbar cannot be used for inflating multiple line objects  so it is impossible to add Tabs to it  If you want to use a Toolbar like a TabWidget you can insert some Tab Objects to it  but only with the old Holo style   Here there is a custom Library that uses v7 Toolbar like TabWidget with the new Material Design animations  but it uses the same methods from the old ActionBar Tabs  so you can attach your ViewPager to it

The new Android Design Support Library adds TabLayout  providing a tab implementation that matches the material design guidelines for tabs  A complete walkthrough of how to implement Tabs and ViewPager can be found in this video  Now deprecated  The PagerTabStrip is part of the support library  and has been for some time  and serves as a direct replacement  If you prefer the newer Google Play style tabs  you can use the PagerSlidingTabStrip library or modify either of the Google provided examples SlidingTabsBasic or SlidingTabsColors as explained in this Dev Bytes video
