In res folder create one folder menu like drawable

Create new xml file optionmenu.xml in that folder.

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@+id/menuitem" 
        android:title="Prefs">
    </item>
         <item android:id="@+id/menuitem1" 
        android:title="Prefs1">
    </item>


</menu>

In onCreate method write this code....

setOptionMenu(R.menu.optionmenu);

and in overide method of Menu write this code.....

@Override
    public boolean onOptionsItemSelected(MenuItem menu) {
        switch (menu.getItemId()) {
        case R.id.menuitem:
            startActivity(new Intent(this, Prefs.class));
            break;

case R.id.menuitem1:
            startActivity(new Intent(this, Prefs1.class));
            break;
        default:
            break;
        }

        return true;
    }
