TabHost tabHost = getTabHost();有关问题

TabHost tabHost = getTabHost();问题
后面gettabhost有错误The method getTabHost() is undefined for the type tabhost

------解决方案--------------------
TabHost tabHost = (TabHost)getTabHost();
------解决方案--------------------
不是说你这方法未定义么！？
Activity***.this.getTabHost();或mContext.getTabHost();
