通过TabWidget实现
实现方式二：隐藏TabWidget，通过RadioGroup和RadioButton实现底部菜单栏
【核心代码】
实现方式一：通过TabWidget实现
这种方式主要是在布局中将TabWidget标签嵌套在RelativeLayout中，并且在TabWidget标签中中设置 android:layout_alignParentBottom="true"
另外，下划线和选项卡之间的线去除的方法时在TabWidget标签中设置属性android:tabStripEnabled="false"

实现方式二：隐藏TabWidget，通过RadioGroup和RadioButton实现底部菜单栏
这种方式更漂亮，也更灵活，网上基本用的是这种方式，通过setCurrentTabByTag来切换不同的选项卡
