刚开始从网上找了一些代码，使用的是TabActivity，但运行的时候总是异常退出，后来看帮助说4.0版TabActivity已过时，要用Fragment替代。。。。然后修来改去。。。。。。一直不能正常运行。。。。。。
后来下定决心还是用TabActivity去试试，一个个错误去查找，终于好了。。。。。。。。

//设置程序默认打开的标签

}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.

}
}
至于tab里面实际的内容，直接新建几个Activity就可以了。
然后运行就可以了。。。。
