<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    tools:context="in.nfnlabs.stormit.Parent">
    <item
        android:id="@+id/action_settings"
        android:orderInCategory="100"
        android:title="@string/action_settings"

</menu>

If u want to add icon, use this:

<item android:id="@+id/action_settings" 
    android:title="@string/action_settings"      
    android:icon="@drawable/bookmark"
    android:orderInCategory="100" 
    app:showAsAction="always" />

In your activity class inflate the menu like below:

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.addnew, menu);
    return true;
}

If you want to perform actions in menu this can be achieved by onOptionsItemSelected

public boolean onOptionsItemSelected(MenuItem item) {
    int i = item.getItemId();
    if(i==R.id.action_settings) {
        Toast.makeText(getApplicationContext(), "Bookmark", Toast.LENGTH_SHORT).show();
    }
}
