android - fragment 中的 StackOverflow 异常

Question

我有一个带有 5 个选项卡的 tabhost，它们是 FragmentActivity。其中一个包含 7 个 View 的序列。我认为每个都是一个 fragment ，但当我到达 fragment 7 时，应用程序爆炸了。

当我在每个 fragment 中按下继续按钮时，我以这种方式开始一个新 fragment :

   MyFragment newFragment = new MyFragment ();
    FragmentTransaction transaction = getFragmentManager().beginTransaction();
    transaction.replace(R.id.publish_map_direction, newFragment);
    transaction.addToBackStack(null);
    transaction.commit();

这是错误:

我应该以不同的方式构建我的应用程序吗？

Answer 1

是的。

我建议只使用 fragment ，而不是在选项卡宿主中嵌套 fragment Activity 。我通常会创建一个标签栏，并在其下方放置一个框架布局，然后我将 fragment 放入其中。然后我根据点击的内容替换 fragment 。这绝对有帮助，因为我认为您同时处理的事情太多了。
