在tabhost中添加选项卡时，“IllegalStateException：Activity已被销毁”

Question

我想在tabhost中的listview中显示一个对话框。在这个对话框里面我想放另一个tabhost。

但是当我想在第二个tabhost中添加一个标签时，我得到了这个堆栈跟踪：

这是我如何设置我的seconde tabhost：

    FragmentTabHost _tabHost  = (FragmentTabHost) view.findViewById(android.R.id.tabhost);
    _tabHost.setup(_context, getSupportFragmentManager(), android.R.id.tabcontent);

    Bundle extras = new Bundle();
    extras.putString("profil_id", _id_profil);
    _tabHost.setCurrentTab(0);
    _tabHost.addTab(_tabHost.newTabSpec("Posts").setIndicator("Posts"), PopupPrefTab.class, extras);

你有任何想法让这项工作？
