java - 膨胀类 fragment 谷歌地图时出错

标签 java android google-maps

我正在尝试完成本教程:http://www.tutorialspoint.com/android/android_google_maps.htm

这是代码:

public class ViewMapActivity extends FragmentActivity {

    static final LatLng TutorialsPoint = new LatLng(21 , 57);
       private GoogleMap googleMap;
       @Override
       protected void onCreate(Bundle savedInstanceState) {
          //super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_view_map);
          try { 
                if (googleMap == null) {
                   googleMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
                }
             googleMap.setMapType(GoogleMap.MAP_TYPE_HYBRID);
             Marker TP = googleMap.addMarker(new MarkerOptions().position(TutorialsPoint).title("TutorialsPoint"));

          } catch (Exception e) {
             e.printStackTrace();
          }

       }
}

布局:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#0099cc"
tools:context="com.androidpoiservice.ViewMapActivity" >

  <fragment
  android:id="@+id/map"
  android:name="com.google.android.gms.maps.MapFragment"
  android:layout_width="match_parent"
  android:layout_height="match_parent"/>

  </RelativeLayout>

和 list :

这是我得到的错误:

最佳答案

将其添加为元标记作为应用程序标记的子标记

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name">
    <activity
     ...// rest of the code
    </activity>
     <meta-data android:name="com.google.android.gms.version" 
     android:value="@integer/google_play_services_version" />
    <!-- Goolge API Key -->
    <meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="api key" />
 </application>

改变这个

public class ViewMapActivity extends FragmentActivity

到

public class ViewMapActivity extends Activity

编辑:

取消注释

 //super.onCreate(savedInstanceState);
