mTabHost =（TabHost）findViewById（android.R.id.tabhost）;而不是使用mTabHost = getTabHost（）; – Akram

請發佈您的LogCat。 – Barak

查看ActionBarSherlock [片段標籤示例]（https://github.com/JakeWharton/ActionBarSherlock/blob/master/samples/fragments/src/com/actionbarsherlock/sample/fragments/FragmentTabs.java） – antew

的問題是，在你的XML文件，其中包含tabhost，你必須將它從@android：id/tabhost改爲@ + id/tabhost。
