Menu > items.xml:

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
    <item 
        android:id="@+id/phone"
        android:title="@string/phone"

    <item 
        android:id="@+id/camera"
        android:title="@string/camera"
        android:icon="@drawable/camera"
        android:showAsAction="ifRoom|withText"        
    />

    <item

        android:icon="@drawable/email"
        android:showAsAction="ifRoom|withText"        
    />

</menu>

Manifest.xml:

 <application
        android:icon="@drawable/ic_launcher"
        android:uiOptions="splitActionBarWhenNarrow"
        android:allowBackup="true" >

        <activity
            android:name="com.sample.menu.HomeActivity"
            android:label="Demo App"                        
            >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <activity
            android:name="com.sample.menu.FirstActivity"
            android:label="First Activity">
            <intent-filter>
                <action android:name="com.sample.menu.second" />
                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
        </activity>     

    </application>

FirstActivity.java:

 public class FirstActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);     
        this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
        getActionBar().setDisplayHomeAsUpEnabled(true);
        setContentView(R.layout.activity_first);        
        getOverflowMenu();
    }

Answer 1

for your Question 2: in onCreate()

this.requestWindowFeature(Window.FEATURE_NO_TITLE);

this is to make action bar icon transparent

getActionBar().setIcon(new ColorDrawable(getResources().getColor(android.R.color.transparent))); 

in Manifest.xml

<android:theme="@android:style/Theme.NoTitleBar">

requestWindowFeature(Window.FEATURE_NO_TITLE);
