main2.xml显然没有错误。 main.xml也是一样，但我认为问题出在某处。
该应用程序的快速总结：它旨在使用谷歌地图onClick按钮，但我收到错误，所以我可以只加载测试主菜单。 XML
我没有足够的代表张贴图片，以便错误PIC可以发现here我无法让Google Maps API在我的Android应用程序（V2）上工作
main2.xml

你必须在你的活动中输入“com.example.clubnightsdeals.R;' –
尝试'main2.xml'将'fragment'放入'FrameLayout'中，或者将fragment的类设置为'SupportMapFragment'。 –
你的最低api水平是多少？ – GrIsHu
