第二次打开 SupportMapFragment 时出错

Question

第二次打开我的 SupportMapFragment（Android 地图 v2）（调用 setContentView）时，出现以下错误：

        this.map = ((SupportMapFragment) activity.getSupportFragmentManager()
            .findFragmentById(R.id.hits_map)).getMap();
    }
}

我不知道这个错误是什么意思。有人可以解释一下吗？

Answer 1

更新： 作为替代解决方案（我认为更好），您可以使用描述的 MapView：here

我在使用选项卡实现时遇到了类似的问题。使用 Google Maps V2，您会被 SupportMapFragment 困住，因此无法选择使用 MapView。在 juanmeanwhile 的帖子和在这里找到的评论 #1 (https://code.google.com/p/gmaps-api-issues/issues/detail?id=5064#c1) 之间，我设法弄清楚我做错了什么。

因此，对于遇到重复 id 错误的任何其他人，请确保您以编程方式声明片段，而不是在 XML 中。这可能意味着嵌套布局。

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:map="http://schemas.android.com/apk/res-auto"
   android:layout_width="match_parent"
   android:layout_height="match_parent" >

<!-- Lots of fancy layout -->   

<RelativeLayout
        android:id="@+id/map"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
    </RelativeLayout>
</RelativeLayout>

然后您需要以编程方式创建片段，但需要仔细考虑片段生命周期 (http://developer.android.com/reference/android/app/Fragment.html#getChildFragmentManager())。为确保在正确的时间创建所有内容，您的代码应如下所示（取自注释 #1）。

public class MyFragment extends Fragment {

private SupportMapFragment fragment;
private GoogleMap map;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    return inflater.inflate(R.layout.layout_with_map, container, false);
}

@Override
public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);
    FragmentManager fm = getChildFragmentManager();
    fragment = (SupportMapFragment) fm.findFragmentById(R.id.map);
    if (fragment == null) {
        fragment = SupportMapFragment.newInstance();
        fm.beginTransaction().replace(R.id.map, fragment).commit();
    }
}

@Override
public void onResume() {
    super.onResume();
    if (map == null) {
        map = fragment.getMap();
        map.addMarker(new MarkerOptions().position(new LatLng(0, 0)));
    }
}
}

希望这可以节省一些时间。

Answer 2

不要在布局中声明 de SupportMapFragment，而是以编程方式进行，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();

Answer 3

我花了半天时间解决了这个问题，只是找到了解决方法。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 :-(
    }
}

我整天都在寻找这个问题的解决方案，在这里阅读了所有的解决方法，我找到了解决问题的方法。我将发布所有代码，因为这个问题缺乏完整的答案，只是一些与完整场景匹配并且对任何人都有帮助的小 sn-p。

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;
    }

}

通过调试，你会发现片段如何操作并不重要，onDestroyMethod等不需要botter，因为null的验证，只是对对象的当前实例进行操作。

享受吧！ ;)

我遇到了这个问题，在我的 android 日志中发现我的硬件加速没有打开。在我的 AndroidManifest 中打开它后，我多次显示地图不再是问题。我使用的是 x86 模拟器。

            ft.remove(fragment);
            ft.commit();
        }
    }


}

我的 Xml 文件如下所示：-

<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/map"
    android:name="com.google.android.gms.maps.MapFragment"

    android:layout_height="match_parent" />

需要注意的最重要的一点是，不要将 app.Fragment 与 v4.Fragments 混合使用，否则应用程序会严重崩溃。

如您所见，我使用 app.Fragment 附加和删除我的 MapView 片段

希望对大家有所帮助

我尝试了这里提出的各种解决方案，恕我直言，最好的一个是 MapView。无论如何，我找到了另一种可以满足您需求的解决方案（或者可能不）。

我的SupportMapFragment 包含在带有 3 个标签的 ViewPager+FragmentPagerAdapter 中。所以我只是将 ViewPager 配置为永远不会破坏 SupportMapFragment 所在的选项卡。

viewPager.setOffScreenPageLimit(2);
viewPager.setAdapter(...);

通过此调用，ViewPager 将始终在当前页面之后维护两页，在当前页面之前维护两页，因此我的三个选项卡都不会被销毁/重新创建。

问题解决了:)

注意内存消耗会增加

private MainActivity mainActObj;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    mainActObj = getMainActivity();
}

@SuppressWarnings("unchecked")
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

    if (mainActObj.mapView == null) {
        return mainActObj.mapView = inflater.inflate(R.layout.fragment_map,
                null);
    }

    else {
        ViewGroup parent = (ViewGroup) mainActObj.mapView.getParent();
        if (parent != null) {
            parent.removeView(mainActObj.mapView);
        }

        try {
            return mainActObj.mapView = inflater.inflate(
                    R.layout.fragment_map, container, false);
        } catch (InflateException except) {
            return mainActObj.mapView;
        }
    }

}

试试这个代码

  @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
         finder = new LocationFinder(getActivity());

             view = inflater.inflate(R.layout.fragment_secondfragement, container, false);



                        initMap();

        
      //  getLocation();
        return view;

    }


    public void initMap(){

        if (map == null) {
            mapFragment = (SupportMapFragment) getChildFragmentManager()
                    .findFragmentById(R.id.map);
        }

        map = mapFragment.getMap();
        map.setMyLocationEnabled(true);
        map.getUiSettings().setMyLocationButtonEnabled(true);

    }

我有同样的问题并且通过动态创建谷歌地图解决了。你要做的是创建一个扩展SupportMapFragment的类班级。

此方法适用于 gingerbread to lollipop 和 嵌套片段，因为它会动态创建地图，因此不必担心删除片段或类似的东西.

第一步：

public class DynamicMapFragment extends SupportMapFragment {

    public GoogleMap googleMap;
    public View mOriginalContentView;
    public static int statusGooglePlayService;    

    @Override
    public void onCreate(Bundle arg0) {
        super.onCreate(arg0);
    }

    @Override
    public View onCreateView(LayoutInflater mInflater, ViewGroup parent,
            Bundle arg2) {

        mOriginalContentView = super.onCreateView(mInflater, parent, arg2);

       //this is for getting height of the phone screen
        DisplayMetrics displaymetrics = new DisplayMetrics();
        getActivity().getWindowManager().getDefaultDisplay()
                .getMetrics(displaymetrics);
        int height = displaymetrics.heightPixels;

        //Here you can define the height of the map as you desire
        FrameLayout.LayoutParams parentLayout = new FrameLayout.LayoutParams(
                FrameLayout.LayoutParams.MATCH_PARENT, height / 3);

        mOriginalContentView.setLayoutParams(parentLayout);
        return mOriginalContentView;
    }

    @Override
    public View getView() {
        return mOriginalContentView;
    }

    @Override
    public void onInflate(Activity arg0, AttributeSet arg1, Bundle arg2) {
        super.onInflate(arg0, arg1, arg2);
    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        googleMap = getMap();

        statusGooglePlayService = GooglePlayServicesUtil
                .isGooglePlayServicesAvailable(getActivity());
        if (statusGooglePlayService == ConnectionResult.SUCCESS) {
            if (googleMap != null) {
                // do whatever you want to do with map
            }
        } else {
            Dialog dialog = GooglePlayServicesUtil.getErrorDialog(
                    statusGooglePlayService, getActivity(), -1);
            dialog.show();
        }
    }

}

然后从Activity中调用上面创建的类，Fragment像这样：

第二步：

//Calling the method from a fragment
private void createMap(View rootView) {
        FrameLayout mapLayout = (FrameLayout)rootView.findViewById(R.id.location_map);
        FragmentTransaction mTransaction = getActivity()
                .getSupportFragmentManager().beginTransaction();
        SupportMapFragment mFRaFragment = new DynamicMapFragment();
        mTransaction.add(mapLayout.getId(), mFRaFragment);
        mTransaction.commit();

        try {
            MapsInitializer.initialize(activity);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

您必须添加 Framelayout 的片段的 XML 布局 地图

的片段

第三步：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >



    <FrameLayout
        android:id="@+id/location_map"
        android:layout_width="match_parent"
        android:layout_height="250dp"
        android:layout_weight="0" />

      <!--  You can add any other view also whatever you want to add 

      <Button
        android:layout_width="match_parent"
        android:layout_height=""wrap_content""
        android:layout_weight="0" />    -->

</LinearLayout>

只要穿上 onCreateView

if (view != null) {
        ViewGroup parent = (ViewGroup) view.getParent();
        if (parent != null)
            parent.removeView(view);
    }

view = inflater.inflate(R.layout.map, container, false);
