使用Fragment让程序界面一分为多
Fragment类型的接口具有以下性质：
1、程序运行界面可有由多个Fragment组成；
2、每一个Fragment 都有各自独立的运行状态。
3、在程序运行过程中，Fragment可以动态的加入和移除。
<fragment android:id="@+id/fragGame" android:name="tw.android.GameFragment" android:layout_width="0dp" android:layout_height="fill_parent" android:layout_weight="1" />
<fragment>便签使用注意事项
1、fragment 的开头字母必须小写
2、每一个<fragment>标签的都要设置android:id 的属性
3、<fragment>的name属性必须制定使用Fragment类，其要加上完整的组件路径名称。
一下代码是一个猜拳游戏：
