Android谷歌地图

概述我尝试在我的应用程序中添加GoogleMAPApiv2.但我得到例外.例外是java.lang.RuntimeException:UnabletostartactivityComponentInfo{info.androidhive.googlemapsv2/info.androidhive.googlemapsv2.MainActivity}:android.view.InflateException:BinaryXMLfileline

我尝试在我的应用程序中添加Google MAP API v2.但我得到例外.例外是

 java.lang.RuntimeException: Unable to start activity ComponentInfo{info.androIDhive.Googlemapsv2/info.androIDhive.Googlemapsv2.MainActivity}: androID.vIEw.InflateException: Binary XML file line #5: Error inflating class fragment

这是我的xml类

<?xml version="1.0" enCoding="utf-8"?><relativeLayout xmlns:androID="http://schemas.androID.com/apk/res/androID"    androID:layout_wIDth="fill_parent"    androID:layout_height="fill_parent" >    <fragment        androID:ID="@+ID/map"        androID:name="com.Google.androID.gms.maps.MapFragment"        androID:layout_wIDth="match_parent"        androID:layout_height="match_parent"/></relativeLayout>

这是我的主要课程

public class MainActivity extends Activity {    private GoogleMap _GoogleMap=null;    @OverrIDe    protected voID onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentVIEw(R.layout.activity_main);        try        {            //loading map            initilizeMap();            _GoogleMap.setMapType(GoogleMap.MAP_TYPE_norMAL);            _GoogleMap.setMyLocationEnabled(true);               } catch (Exception e) {            e.printstacktrace();        }    }    private voID initilizeMap() {        if(_GoogleMap==null)        {            _GoogleMap=((MapFragment)getFragmentManager().findFragmentByID(R.ID.map)).getMap();            if (_GoogleMap == null) {                Toast.makeText(getApplicationContext(),                        "Sorry! unable to create maps", Toast.LENGTH_SHORT)                        .show();            }        }    }    @OverrIDe    protected voID onResume() {        // Todo auto-generated method stub        super.onResume();        initilizeMap();    }}

这是我的logcat

解决方法:

您应该使用SupportMapFragment而不是MapFragment.

更改

<fragment    androID:ID="@+ID/map"    androID:name="com.Google.androID.gms.maps.MapFragment"    androID:layout_wIDth="match_parent"    androID:layout_height="match_parent"/>

至

<fragmentandroID:ID="@+ID/map"androID:name="com.Google.androID.gms.maps.SupportMapFragment"androID:layout_wIDth="match_parent"androID:layout_height="match_parent"/>

也改变

   _GoogleMap=((MapFragment)getFragmentManager().findFragmentByID(R.ID.map)).getMap();

至

_GoogleMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentByID(        R.ID.map)).getMap(); 

而且如果你在旧设备上使用片段(precomb之前),你应该始终从FragmentActivity扩展你的Activity.

并检查

将Google Play服务版本添加到您应用的清单中

Edit your application’s AndroIDManifest.xml file, and add the
following declaration within the element. This embeds the version of
Google Play services that the app was compiled with.

您只需添加<元数据>在< application>下标记到您的AndroIDManifest.xml中

....<application><Meta-data androID:name="com.Google.androID.gms.version"   androID:value="@integer/Google_play_services_version" /></application>

这是因为最新的Google Play服务需要版本名称,使用< Meta-data .. />来提及.在AndroIDManifest.xml中
