TabHost是整个Tab的容器，包括两部分，TabWidget和FrameLayout。TabWidget就是每个tab的标签，FrameLayout则是tab内容
TabHost的二种实现方式： 第一种：继承TabActivity
1、如果我们使用extendsTabAcitivty，如同ListActivity，TabHost必须设置为@android:id/tabhost 2、TabWidget必须设置android:id为@android:id/tabs 3、FrameLayout需要设置android:id为@android:id/tabcontent
第二种：只是单纯的继承Activity类
布局文件 和上面一样 只是TabHost 的id 换为
tabHost = (TabHost)findViewById(R.id.m_tabhost); //如果通过findViewById得到TabHost一定要调用 TabHost.setup(); LocalActivityManagerlocalAcManager = new LocalActivityManager(MainActivity.this,true); localAcManager.dispatchCreate(savedInstanceState); tabHost.setup(localAcManager);
还可以自定义标签，将TabWidget android:visibility="gone" 然后自己弄些控件替代
另一实现自定义底部菜单
