Cannot start Android 4.0 Split Action action bar

Question

I followed the development pages on the Android developer site, but I can’t get the action bar to split to the top and bottom of the screen.

I have an xml menu defined with a few options:

<?xml version="1.0" encoding="utf-8"?> <menu xmlns:android="http://schemas.android.com/apk/res/android"> <item android:id="@+id/stop_services" android:icon="@drawable/ic_launcher" android:title="@string/stop" android:showAsAction="ifRoom|withText"/> <item android:id="@+id/start_services" android:icon="@drawable/pushpin" android:title="@string/start" android:showAsAction="ifRoom|withText"/> </menu> 

In my manifest, I installed uiOption:

 <activity android:label="@string/app_name" android:name=".ProxilenceHome" uiOptions="splitActionBarWhenNarrow" > 

I load menu items into action as follows:

 public boolean onCreateOptionsMenu(Menu menu) { MenuInflater inflater = getMenuInflater(); inflater.inflate(R.menu.home_menu, menu); return true; } 

But when testing the application, the action bar never breaks up. Does anyone know the problem / if I missed something?

Many thanks.

Answer 1

Using android:uiOptions="splitActionBarWhenNarrow" works for me.

Without "android:" it does not work

Answer 2

using this in landscape mode, the navigation tabs are separated, but in portrait mode this does not work.

  final ActionBar bar = this.getActionBar(); bar.setDisplayHomeAsUpEnabled(false); bar.setDisplayOptions(0, ActionBar.DISPLAY_SHOW_TITLE); bar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS); mTabsAdapter = new TabsAdapter(this, mViewPager); Tab tab1=mTabsAdapter.addTab(bar.newTab().setText("DemoGraphics"),ListFragmentDemo.PatientFragment.class, null); public boolean onCreateOptionsMenu(Menu menu) { MenuInflater inflater=getMenuInflater(); inflater.inflate(R.menu.mainmenu, menu); super.onCreateOptionsMenu(menu); return true; } 

mainmenu.xml

  <menu xmlns:android="http://schemas.android.com/apk/res/android"> <item android:id="@+id/menu_dCollection" android:icon="@drawable/overflowmenu" android:showAsAction="ifRoom|withText" > <menu> <item android:id="@+id/menu_demo" android:title="DemoGraphics" /> <item android:id="@+id/menu_visits" android:title="Visits" /> <item android:id="@+id/menu_vitals" android:title="Vitals" /> </menu> </item> <item android:id="@+id/add" android:showAsAction="ifRoom" android:title="Add" android:icon="@drawable/ic_action_open"></item> <item android:id="@+id/previous" android:showAsAction="ifRoom" android:title="Back" android:icon="@drawable/back"></item> <item android:id="@+id/nextFragment" android:showAsAction="ifRoom" android:title="Next" android:icon="@drawable/next"></item> <item android:id="@+id/menu_search" android:showAsAction="ifRoom" android:title="Search" android:actionViewClass="android.widget.SearchView" android:icon="@drawable/search" /> </menu> 

in manifest.xml

 <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" android:installLocation="preferExternal" package="savy.exam.actionbartabspager" android:versionCode="1" android:versionName="1.0" android:uiOptions="splitActionBarWhenNarrow" > 

Answer 3

Try adding this line to your xml menu:

 <menu xmlns:android="http://schemas.android.com/apk/res/android" xmlns:myapp="http://schemas.android.com/apk/res-auto" > 

Then in the item element:

 myapp:showAsAction="always|withText" 

It helps me.
