[Study Note] Options 메뉴 제어하기~~

onPrepareOptionsMenu 를 이용하면 구성된 메뉴가 활성화 되기 전에 필요한 처리를 할 수 있다.

<?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"
