mTabHost.setup出错

[kaka4524]

mTabHost = (FragmentTabHost)findViewById(android.R.id.tabhost);
mTabHost.setup(this, getSupportFragmentManager(), R.id.realtabcontent);

很常规的用法，网上找到很多这样的例子，但是执行setup后出现以下错误：
05-30 11:25:48.230: E/AndroidRuntime(5923): Caused by: java.lang.RuntimeException: Your TabHost must have a FrameLayout whose id attribute is 'android.R.id.tabcontent'

我没有v4的源码，跟到tabhost里面执行了setup（）无参方法。。。。
请问这个是哪里的问题？

没人回答吗。。。

        setContentView(R.layout.fragment_tabs);
        mTabHost = (FragmentTabHost)findViewById(android.R.id.tabhost);
        mTabHost.setup(this, getSupportFragmentManager(), R.id.realtabcontent);

        mTabHost.addTab(mTabHost.newTabSpec("simple").setIndicator("Simple"),
                FragmentStackSupport.CountingFragment.class, null);
        mTabHost.addTab(mTabHost.newTabSpec("contacts").setIndicator("Contacts"),
                LoaderCursorSupport.CursorLoaderListFragment.class, null);
        mTabHost.addTab(mTabHost.newTabSpec("custom").setIndicator("Custom"),
                LoaderCustomSupport.AppListFragment.class, null);
        mTabHost.addTab(mTabHost.newTabSpec("throttle").setIndicator("Throttle"),
                LoaderThrottleSupport.ThrottledLoaderListFragment.class, null);

上面是google的example，但是 mTabHost.setup调用源码如下

   public void setup(Context context, FragmentManager manager, int containerId) {
        ensureHierarchy(context);  // Ensure views required by super.setup()
        super.setup();
        mContext = context;
        mFragmentManager = manager;
        mContainerId = containerId;
        ensureContent();
        mRealTabContent.setId(containerId);

        // We must have an ID to be able to save/restore our state.  If
        // the owner hasn't set one at this point, we will set it ourself.
        if (getId() == View.NO_ID) {
            setId(android.R.id.tabhost);
        }
    }

super.setup();就会调用到TabHost，一定会去找android.R.id.tabcontent。。。。 请大卡们指点一下怎么使用。。。 我网上搜索都这样用，别人不出问题。。。。想不通有什么地方出纰漏
