第二次打开SupportMapFragment时出错

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

我不知道这个错误是什么意思。 有人可以解释这个吗？

Answer 1

不是在布局中声明de SupportMapFragment，而是以编程方式执行，并确保使用getChildFragmentMananger而不是传统的getFragmentManager（）来创build片段。

  mMapFragment = SupportMapFragment.newInstance(); FragmentTransaction fragmentTransaction = mMapFragment.getChildFragmentManager().beginTransaction(); fragmentTransaction.add(R.id.map_root, mMapFragment); fragmentTransaction.commit(); 

请保留此SupportMapFragment mMapFragment，因为您将需要它来检索GoogleMap对象：

  GoogleMap map = mMapFragment.getMap(); 

Answer 2

更新：作为一个替代解决scheme（我认为更好），你可以使用一个MapView： 这里描述

在处理标签实现时，我遇到了类似的问题。 使用Google Maps V2时，您只能使用SupportMapFragment，因此不能使用MapView。 在这里发表评论＃1和发现在这里（ https://code.google.com/p/gmaps-api-issues/issues/detail?id=5064#c1 ），我设法弄清楚我做错了什么。

所以，对于任何其他人得到重复的id错误，请确保您以编程方式声明片段，而不是XML。 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> 

然后你需要以编程方式创build你的片段，但是需要仔细考虑片段生命周期（ http://developer.android.com/reference/android/app/Fragment.html#getChildFragmentManager（）; ）。 为了确保在正确的时间创build一切，你的代码应该像这样（来自注释＃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 3

我已经花了半天的时间解决了这个问题，只find了解决办法。 覆盖YourFragment类中的onCreate方法：

 public void onCreate(Bundle savedInstanceState) { setRetainInstance(true); super.onCreate(savedInstanceState); } 

并重写你的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 :-( } } 

Answer 4

这一天我一直在寻找解决这个问题的办法，在这里阅读所有的工作，我find了解决这个问题的办法。 我将发布所有的代码，因为这个问题没有一个完整的答案，只是一些小的片段，完全匹配一个完整的场景，并帮助任何人。

 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debugging，你会注意到片段的运行方式并不重要，你不需要为onDestroyMethod创buildbotter等，因为null的validation只是在对象的当前实例下运行。

请享用！ ;）

Answer 5

我遇到了这个问题，并在我的Android日志中发现我的硬件加速未打开。 在AndroidManifest中打开之后，我多次显示地图不再是问题。 我正在使用x86模拟器。

Answer 6

经过大量的命中和尝试，我终于成功地在我的应用程序中使用MapView Fragment，结果如下所示：

，这里是我的MapView片段类：

 import android.content.Context; import android.location.Location; import android.location.LocationListener; import android.location.LocationManager; import android.os.Bundle; import android.support.v4.app.Fragment;

i < 10; i++) { // random latitude and logitude double[] randomLocation = createRandLocation(latitude, longitude); // Adding a marker MarkerOptions marker = new MarkerOptions().position( new LatLng(randomLocation[0], randomLocation[1])).title( "Hello Maps " + i); Log.e("Random", "> " + randomLocation[0] + ", " + randomLocation[1]); // changing marker color if (i == 0) marker.icon(BitmapDescriptorFactory .defaultMarker(BitmapDescriptorFactory.HUE_AZURE)); if (i == 1) marker.icon(BitmapDescriptorFactory .defaultMarker(BitmapDescriptorFactory.HUE_BLUE));

googleMap.addMarker(marker); // Move the camera to last position with a zoom level if (i == 9) { CameraPosition cameraPosition = new CameraPosition.Builder() .target(new LatLng(randomLocation[0], randomLocation[1])) .zoom(15).build(); googleMap.animateCamera(CameraUpdateFactory .newCameraPosition(cameraPosition)); } } } /* * creating random postion around a location for testing purpose only */ private double[] createRandLocation(double latitude, double longitude) { return new double[] { latitude + ((Math.random() - 0.5) / 500), longitude + ((Math.random() - 0.5) / 500), 150 + ((Math.random() - 0.5) * 10) }; } @Override public void onLocationChanged(Location location) { if (null != googleMap) { // To get lattitude value from location object double latti = location.getLatitude(); // To get longitude value from location object double longi = location.getLongitude(); // To hold lattitude and longitude values LatLng position = new LatLng(latti, longi); createMarker(latti, longi); // Creating object to pass our current location to the map MarkerOptions markerOptions = new MarkerOptions();

locationManager.removeUpdates(this); android.app.Fragment fragment = getActivity().getFragmentManager() .findFragmentById(R.id.map); if (null != fragment) { android.app.FragmentTransaction ft = getActivity() .getFragmentManager().beginTransaction(); ft.remove(fragment); ft.commit(); } } } 

我的Xml文件看起来像这样：

 <?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_width="match_parent" android:layout_height="match_parent" /> 

最重要的是要注意的是，不要混用app.Fragment与v4.Fragments其他应用程序将严重崩溃。

正如你所看到的，我已经使用app.Fragment来附加和删除我的MapView片段

希望它会帮助别人

Answer 7

我尝试了这里提出的各种解决scheme，最好的一个恕我直言是MapView。 无论如何，我发现另一个解决scheme，可以满足您的需求（或者不）。

我有一个ViewPager+FragmentPagerAdapter有3个选项卡的我的SupportMapFragment 。 所以我刚刚configurationViewPager的方式，它永远不会破坏SupportMapFragment的标签。

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

通过这个调用，ViewPager将始终在当前页面之前和之后两页保留两个页面，所以我的三个选项卡都不会被销毁/重新创build。

问题解决了 ：）

请注意，内存消耗会增加

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); } 

Answer 10

我有同样的问题，并通过dynamic创build谷歌地图解决。 你所要做的就是创build一个正在扩展SupportMapFragment类的类。

这种方法适用于姜饼，棒棒糖和嵌套片段，因为它会dynamic地创build地图，所以不必担心删除片段或类似的东西。

步骤1：

 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，Fragment调用上面创build的类，如下所示：

第2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(); } } 

XML布局的片段，你必须添加Framelayout而不是map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> 

Answer 11

只要把onCreateView

 if (view != null) { ViewGroup parent = (ViewGroup) view.getParent(); if (parent != null) parent.removeView(view); } view = inflater.inflate(R.layout.map, container, false);
