Android tabHost是不可见的？为什么不用这个XML显示？

In my XML editor on Eclipse I see the tabhost, and it looks exactly how I want it, but when I run it I don't see the tabHost at all, how can I make sure it's visable?
在Eclipse上的XML编辑器中,我看到tabhost,它看起来就像我想要的那样,但是当我运行它时,我根本看不到tabHost,我怎样才能确保它是可见的?
This is my XML. Again, the editor shows it, but when I run it it doesn't, the activity which inflates it doesn't do much yet, just change the two textfields. Any ideas?
这是我的XML。再次,编辑器显示它,但是当我运行它时它没有,膨胀它的活动还没有做太多,只需更改两个文本字段。有任何想法吗?

You have to do this programmatically, for example:
您必须以编程方式执行此操作,例如:
tabhost = (TabHost) findViewById(android.R.id.tabhost);
tabhost.setup();
TabSpec ts = tabhost.newTabSpec("tag1");
ts.setContent(R.id.tab1);
ts.setIndicator("First Tab");
tabhost.addTab(ts);
ts = tabhost.newTabSpec("tag2");
ts.setContent(R.id.tab2);
ts.setIndicator("Second Tab");
tabhost.addTab(ts);
ts= tabhost.newTabSpec("tag3");
ts.setContent(R.id.tab3);
ts.setIndicator("Third Tab");
tabhost.addTab(ts);
