Android：获取谷歌地图Android API v2时出错

我正在尝试用谷歌地图Android API v2创建谷歌地图应用程序。我已经安装了Google Play服务和Google Maps Mobile SDK for Business。当我在main.xml中添加代码并运行程序时，它将提示错误

main.xml中的代码

<fragment 
      android:id="@+id/map"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:name="com.google.android.m4b.maps.MapFragment"/>

您是否在地图项目中引用了google play services库项目？是的。google play services位于参考库中，请也粘贴您的活动类。@ManishSrivastava

package com.example.googlemap；导入android.os.Bundle；导入android.app.Activity；公共类MainActivity扩展活动{@Override protected void onCreate（Bundle savedInstanceState）{super.onCreate（savedInstanceState）；setContentView（R.layout.main）；}}

@gladys噢，亲爱的，请编辑您的问题。您不能在注释中粘贴所有类。
