split action bar doesn't appear?

i want to make action bar top and down in android 4.03 make code but when i run it it doesn't appear , i don't know what is wrong , i search for reson before asking here but i didn't find anything here is menu/style.xml code:

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

<item 

   android:id="@+id/first"

   android:icon="@drawable/cat"  

    />

<item 

   android:id="@+id/first"

   android:icon="@drawable/phone" 

    />

<item 

   android:id="@+id/first"

   android:icon="@drawable/music" 

    />

<item 

   android:id="@+id/first"

   android:icon="@drawable/dialog" 

    />

<item 

   android:id="@+id/first"

   android:icon="@drawable/file"

    />

<item 

   android:id="@+id/first"

   android:icon="@drawable/contact" 

    />

<item 

   android:id="@+id/first"

   android:icon="@drawable/contact" 

    />    



</menu>

manifest code:

<activity

            android:label="@string/app_name"

            android:name=".CalendarActivity" 

            android:uiOptions="splitActionBarWhenNarrow"

            >

            <intent-filter >

                <action android:name="android.intent.action.MAIN" />



                <category android:name="android.intent.category.LAUNCHER" />

            </intent-filter>

        </activity>





     and activity code:

      @Override

    public boolean onCreateOptionsMenu(Menu menu) {

         super.onCreateOptionsMenu(menu);

         MenuInflater i=getMenuInflater();

         i.inflate(R.menu.style, menu);

         return true;

    }

because this is first use to android 4.0 i'm a little confused, why my items in black color i can't see them ??
