第二次打开SupportMapFragment时出错
第二次打开SupportMapFragment时出错
提问于 2013-01-28 23:34:26
当第二次打开我的SupportMapFragment (安卓地图v2) (调用setContentView)时，我得到以下错误：

}
}我不知道这个错误是什么意思。有人能解释一下吗？

不要在布局中声明de SupportMapFragment，而是通过编程来实现，并确保使用getChildFragmentMananger而不是经典的getFragmentManager()来创建片段。
mMapFragment = SupportMapFragment.newInstance();
FragmentTransaction fragmentTransaction =
mMapFragment.getChildFragmentManager().beginTransaction();
fragmentTransaction.add(R.id.map_root, mMapFragment);
fragmentTransaction.commit(); 保留此SupportMapFragment mMapFragment，因为您需要它来检索GoogleMap对象：
GoogleMap map = mMapFragment.getMap();Stack Overflow用户

我花了半天的时间来解决这个问题，但只找到了一个解决方法。在YourFragment类中覆盖您的onCreate方法：
public void onCreate(Bundle savedInstanceState) {
setRetainInstance(true);
super.onCreate(savedInstanceState);
}并覆盖您的onDestroy方法：
@Override
public void onDestroyView() {
super.onDestroyView();
try {
SupportMapFragment fragment = (SupportMapFragment) getActivity()
.getSupportFragmentManager().findFragmentById(
R.id.multi_inns_on_map);
if (fragment != null) getFragmentManager().beginTransaction().remove(fragment).commit();
} catch (IllegalStateException e) {
//handle this situation because you are necessary will get
//an exception here :-(
}

我花了一整天寻找这个问题的解决方案，阅读了这里所有的变通方法，我找到了解决问题的方法。我将发布所有的代码，因为这个问题缺少一个完整的答案，只是一些与完整场景匹配的小片段，确实对任何人都有帮助。
public class LocationFragment extends Fragment implements View.OnClickListener {
private GoogleMap googleMap;
private static View rootView;
private SupportMapFragment supportMapFragment;
public LocationFragment() {
}
@Override
public void onDestroyView() {
super.onDestroyView();
}
@Override
public void onCreate(Bundle savedInstanceState) {
setRetainInstance(true);
super.onCreate(savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
if(savedInstanceState == null) {
if (rootView != null) {
ViewGroup parent = (ViewGroup) rootView.getParent();
if (parent != null)
parent.removeView(rootView);
}
try{
if(rootView == null)
{
rootView = inflater.inflate(R.layout.fragment_location, container, false);
}
supportMapFragment = (SupportMapFragment) getFragmentManager().findFragmentById(R.id.map);
LocationUtility locationUtility = LocationUtility.getInstance(context);
GoogleMap googleMap = locationUtility.initilizeMap(supportMapFragment);
//More code
} catch (Exception e)
{
e.printStackTrace();
}
}
return rootView;
}
}通过对其进行调试，您将注意到，片段如何操作并不重要，您不需要onDestroyMethod的botter，等等，因为null的验证只与对象的当前实例操作。
尽情享受！;)
