从xml创建menu

从xml创建menu

 

xml代码

<menu xmlns:android="http://schemas.android.com/apk/res/android">
	<!-- This group uses the default category. -->
	<group android:id="@+id/menuGroup_Main">
		<item android:id="@+id/menu_testPick"
		android:orderInCategory="5"
		android:title="Test Pick" />
		<item android:id="@+id/menu_testGetContent"
		android:orderInCategory="5"
		android:title="Test Get Content" />
		<item android:id="@+id/menu_clear"
		android:orderInCategory="10"
		android:title="clear" />
		<item android:id="@+id/menu_dial"
		android:orderInCategory="7"
		android:title="dial" />
		<item android:id="@+id/menu_test"
		android:orderInCategory="4"
		android:title="@+string/test" />
		<item android:id="@+id/menu_show_browser"
		android:orderInCategory="5"
		android:title="show browser" />
	</group>
</menu>

 

java代码

@Override
public boolean onCreateOptionsMenu(Menu menu)
{
MenuInflater inflater = getMenuInflater(); //from activity
inflater.inflate(R.menu.my_menu, menu);
//It is important to return true to see the menu
return true;
}

 

onCreateOptionsMenu 方法一定返回true，如果为false，menu不显示
