虽然网上有很多底部菜单栏的实现方式,但是实现方式各种各样,很多也不符合自己的口味,所以还是总结下底部菜单栏的实现方式,以便以后方便查询使用
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"
main.xml
复制代码

运行效果如下:
---------------------------------------------------
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,网上基本用的是这种方式,通过setCurrentTabByTag来切换不同的选项卡
