准备图片，它们的名字分别为：picture、menu_exit、menu_main、menu_more、menu_news、

menu_selected、menu_sms、pic_m、common_account、common_addmark、common_download、

common_fullscreen、common_history、common_night、common_refresh、icon、menu_contact、

menu_phone、set_button、set_mode、set_nophoto、set_rotation、set_scroll、set_skin、

set_system、set_time、tool_back、tool_copy、tool_file、tool_help、tool_report、

tool_save、tool_share

在strings.xml添加文字信息:

<string name="app_name">ActivityGroup基本菜单</string>

<string name="hello_world">Hello world!</string>

<string name="menu_settings">Settings</string>

<string name="title_activity_my_activity_group_demo">MyActivityGroupDemo</string>

</resources>

在main.xml中:

<LinearLayout

xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="fill_parent"

android:layout_height="fill_parent"

android:background="#000000"

android:gravity="center_horizontal"

android:layout_height="wrap_content"

android:layout_alignParentBottom="true"
