我一直在尝试从 http://androider.blogspot.in/2013/01/google-maps-android-api-v2-example_3.html为 MAP 活动编写代码

但是，我遇到了错误

 import com.google.android.gms.common.ConnectionResult;
 import com.google.android.gms.common.GooglePlayServicesUtil;
 import com.google.android.gms.maps.CameraUpdateFactory;
 import com.google.android.gms.maps.GoogleMap;
 import com.google.android.gms.maps.GoogleMap.OnMapLongClickListener;
 import com.google.android.gms.maps.MapFragment;
 import com.google.android.gms.maps.SupportMapFragment;
 import com.google.android.gms.maps.GoogleMap.OnMapClickListener;
 import com.google.android.gms.maps.model.LatLng;
 import com.google.android.gms.maps.model.MarkerOptions;

它也不可能添加上述导入以及 GoogleMap 类。任何人都可以帮助我摆脱这个，我对 android 和学习我自己很陌生。

您需要拥有 Google Play Services 库项目。您可以从您的 android sdk 中获取它（路径：basepath+android-sdks\extras\google\google_play_services\libproject）。在这个项目的 libs 文件夹中，您将获得一个名为“google-play-services.jar”的 jar 文件。将此 jar 文件放入您的项目 libs 文件夹中，并将 google play services 库项目导入您的工作区并将其添加到您的项目中（为了更安全）。我想它会对你有所帮助。
