[Study Note] 코드 또는 XML 리소스를 이용한 Options 메뉴 구현하기

옵션 메뉴를 구성하는 XML 리소스 파일 내용 res/menu/myoptions.xml

<?xml version="1.0" encoding="utf-8"?>
<menu
  xmlns:android="http://schemas.android.com/apk/res/android">
  <item
      android:id="@+id/MnuNew"
      android:title="New"
      android:icon="@drawable/icon"
      />
  <item
      android:title="selection"
      >
      <menu>
          <item 
              android:id="@+id/MnuSelection1" 
              android:title="Selection1"
              android:icon="@drawable/icon"
              />
          <item 
              android:id="@+id/MnuSelection2" 
              android:title="Selection2"
              />
          <item 
              android:id="@+id/MnuSelection3" 
              android:title="Selection3"
              />
      </menu>
      </item>
</menu>
