我有一个带有 5 个标签的标签主机，它们是FragmentActivity. 其中一个包含一系列 7 个视图。我认为每个都是一个片段，但是当我到达片段 7 时，应用程序爆炸了。

当我在每个片段中按下继续按钮时，我以这种方式开始一个新片段：

   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？

是的。

我建议只使用片段，而不是在选项卡主机内嵌套片段活动。我通常创建一个标签栏，并在其下方有一个框架布局，我将一个片段放入其中。然后我根据点击的内容替换片段。那肯定会有所帮助，因为我认为您同时要做的事情太多了。
