Answer 1

不要只给java.lang.IllegalStateException，可以看一下log信息吗？？error级别的

Answer 3

at cn.yt.test.MainTabhost.onCreate(MainTabhost.java:22)去这个页的22行，看看代码，还有是不是Androidmanifest,xml没有注册该页？？

Answer 4

在使用TabHost时有时出现Did you forget to call 'public void setup(LocalActivityManager activityGroup)，主要是没有继承ActivityGroup和获得ActivityManager解决方案:主页面继承ActivityGroup 而不是 Activity加入 tabHost.setup(this.getLocalActivityManager());
