我目前卡在一個point.If我使用操作欄（NAVIGATION_MODE_TABS）與片段。我想片段是一個活動，它將處理所有的視圖加載和一切。當前fragmented類將擴展Fragment..Right？但我想somethth喜歡擴展活動，然後調用oncreate。動作Android的動作酒吧與片段加載視圖，但我想加載自己加載視圖的活動（如在tabhost）
請幫忙。
enter code here
final TabHost tabHost = getTabHost();//(TabHost) findViewById(R.id.tabhost);// // The activity TabHost
TabHost.TabSpec spec; // Resusable TabSpec for each tab
Intent intent; // Reusable Intent for each tab
// Create an Intent to launch an Activity for the tab (to be reused)
intent = new Intent().setClass(this, X.class);
// Initialize a TabSpec for each tab and add it to the TabHost
spec = tabHost.newTabSpec("jbn jb n").setIndicator("gjngjmb ",
res.getDrawable(R.drawable.home))
.setContent(intent);
tabHost.addTab(spec);
// Do the same for the other tabs
intent = new Intent().setClass(this, MyCoursesActivity.class);
spec = tabHost.newTabSpec("my_course").setIndicator("My Courses",
res.getDrawable(R.drawable.courses))
.setContent(intent);
tabHost.addTab(spec);
intent = new Intent().setClass(this, DashboardActivity.class);
intent.putExtra("course_title", "Aal is well!!!");
spec = tabHost.newTabSpec("dashboard").setIndicator("Dashboard",
res.getDrawable(R.drawable.dashboard))
.setContent(intent);
tabHost.addTab(spec);
enter code here
該代碼使用tabhost我想要做同樣的使用動作條與fragmants爲Android 4.0
