尝试加载Google地图V2时Android应用崩溃[解决！]

问题描述：

我试图在使用分段的同时在我的android应用中实施Google地图V2。尝试加载Google地图V2时Android应用崩溃[解决！]

但是，当我试图查看地图时，代码显示没有错误，它崩溃。

我一直在这个问题上停留了一段时间，所以任何帮助或指针在正确的方向将不胜感激。

地图断枝类：

public class mapFrag extends Fragment { 

MapView mMapView; 
GoogleMap googleMap; 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
     Bundle savedInstanceState) { 
    // inflate and return the layout 
    View v = inflater.inflate(R.layout.fragment_map, container, false); 
    mMapView = (MapView) v.findViewById(R.id.mapView); 
    mMapView.onCreate(savedInstanceState); 
    mMapView.onResume();//needed to get the map to display immediately 

    try { 
     MapsInitializer.initialize(getActivity()); 
    } catch (GooglePlayServicesNotAvailableException e) { 
     e.printStackTrace(); 
    } 

    googleMap = mMapView.getMap(); 



    //Perform any camera updates here 

    return v; 
} 

}

布局XML

编辑通过改变XML解决 - 见下面

<?xml version="1.0" encoding="utf-8"?> 
<com.google.android.gms.maps.MapView 

xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:id="@+id/mapView" />

logcat的

你正在使用Google Maps错误，请阅读文档https://developers.google.com/maps/documentation/android/ – tyczj

答

Caused by: java.lang.ClassNotFoundException: com.google.android.gms.maps.mapview

应该

<com.google.android.gms.maps.MapView

不

<com.google.android.gms.maps.mapview

你也应该阅读

http://developer.android.com/reference/com/google/android/gms/maps/MapView.html

此类的用户必须将包含此视图的Activity或Fragment的所有生命周期方法转发给此类中的相应对象。特别是，你必须在下列方法转发：

onCreate(Bundle) 
onResume() 
onPause() 
onDestroy() 
onSaveInstanceState() 
onLowMemory()

，你可以参考这个

Android - android.view.InflateException: Binary XML file line #8: Error inflating class fragment

Raghunandan上的Spot，总是有些简单的ey？ –

@ c-bradz很高兴能够认真帮助和红色MapView文档。你错过了覆盖一些方法 – Raghunandan

我有生命周期方法实施，试图节省空间，所以我把它们排除在外，因为它不太可能出现问题。再次感谢 –

答

我没有看到你使用任何碎片。它应该是：

<fragment xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/map" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    class="com.google.android.gms.maps.MapFragment"/>
