Android 在另一个片段上设置谷歌地图

我正在为我的一个应用程序创建向导，其中用户必须提供详细信息。当我将我的google地图放入fragment时出现问题。请注意，我有一个framelayout，其中我放入了fragment，在该fragment中我希望有地图，请帮助我

这是我的代码：

我找到了解决方案。我只是在布局中使用了mapview，我做了类似的事情。您是否将不同的片段放在不同的选项卡中？不，我没有选项卡，但当我单击“下一步”按钮时，片段视图显示实际上还有3个片段。我每次单击“下一步”按钮时都会将其替换为“是”，出现空点异常

public class IntroDuction_Main extends FragmentActivity
.................
.......... 
F_map map=new F_map();
            map.setArguments(getIntent().getExtras());
            Transectionfragment(map);
}
private void Transectionfragment(Fragment frag) {
    FragmentManager fragmentManager;
    fragmentManager = getSupportFragmentManager();

    FragmentTransaction transaction = fragmentManager.beginTransaction();

    transaction.setCustomAnimations(android.R.anim.fade_in,
            android.R.anim.fade_out, android.R.anim.fade_in,
            android.R.anim.fade_out);
    transaction.replace(R.id.MainFragment, frag);

    transaction.addToBackStack(null);
    transaction.commit();

}
