Google Maps v2在单击两次时的片段内容中

Question

我正试图在我的应用程序中使用标记在片段中设置Google地图.当我第一次点击它时它起作用,但是当我点击另一个片段然后返回谷歌地图时它会崩溃.不确定是什么问题？任何帮助都会很棒,只有初学者.

继承人代码:

XML

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

Java google maps片段编辑工作代码如下

public class Fragment_8 extends Fragment{

static final LatLng BottleCapp = new LatLng(51.371986, 0.065593);
  private GoogleMap map;
  private static View view;

  @Override
  public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
      if (view != null) {
          ViewGroup parent = (ViewGroup) view.getParent();
          if (parent != null)
              parent.removeView(view);
      }
      try {
          view = inflater.inflate(R.layout.fragment_8, container, false);
      } catch (InflateException e) {
          /* map is already there, just return view as it is */
      }
    map = ((SupportMapFragment)getFragmentManager().findFragmentById(R.id.map)).getMap();

        Marker bottleapp = map.addMarker(new MarkerOptions().position(BottleCapp)
            .title("BottleCapp"));


        // Move the camera instantly to Bottlecapp with a zoom of 15.
        map.moveCamera(CameraUpdateFactory.newLatLngZoom(BottleCapp, 15));

        // Zoom in, animating the camera.
        map.animateCamera(CameraUpdateFactory.zoomTo(10), 2000, null);
        getActivity().getSupportFragmentManager().popBackStack();
        return view;

    }
  }

错误

从您在这里提供的代码中,您尝试使用的对象中存在一些错误,并且您正在混合它们.我在谈论MapFragment你在xml布局文件中使用的对象:

class="com.google.android.gms.maps.MapFragment"

如果你的xml正在使用,MapFragment那么我不明白你为什么要SupportMapFragment在你的活动代码中获取一个对象:

 map = ((SupportMapFragment)getFragmentManager().findFragmentById(R.id.map)).getMap();

很高兴看到您针对您的应用程序定位的API级别,但您需要决定要支持API V11及更低版本的设备,或者您只想支持API V12及更高版本.如果你想支持API V11并且更低,请查看我写的关于在你的应用程序中集成G​​oogle API V2地图的博客文章:

Google Maps API V2

我寻求仅支持更高版本,然后将活动代码更改为:

map = ((MapFragment)getFragmentManager().findFragmentById(R.id.map)).getMap();

并相应地更改您的清单文件.
