android-tabhost - 选项卡中的谷歌地图 v2 错误(片段中的 MapFragment)

Question

我有一个fragmentActivity，我在其中构建了一个tabHost，并且在每个选项卡中都有一个Fragment。好吧，当我选择一个选项卡并传递给其他所有内容时，我有四个选项卡，其中 3 个带有信息，1 个带有片段，其中包含 google-map-v2(是片段中的fragmentMAp，因为我想添加按钮等)进展顺利，但是当我选择 map 选项卡时，在选择其他选项卡并再次选择 map 选项卡时，会抛出错误。

我的观点是这样的:

|__||__|__|__|
| __________ |
|| FRAGMENT ||
||_____   _ ||
|| FRAG| |_|||
|| MAP |    ||
||     |    ||
||_____|    ||
||__________||

这是问题所在，但我不知道为什么只有这个片段有问题:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.monumenos_view_preview, container, false);


return view;
}

Answer 1

最后我找到了解决方案，我删除了 Fragment 中嵌套的 MapFragment:

public void onDestroyView ()
{
      try{
    SupportMapFragment fragment = ((SupportMapFragment) getFragmentManager().findFragmentById(R.id.mapv2));
        FragmentTransaction ft = getActivity().getSupportFragmentManager().beginTransaction();
        ft.remove(fragment);
        ft.commit();
      }catch(Exception e){
      }
    super.onDestroyView();  
}

我从这里得到解决方案:Fragments within Fragments
