我认为这是因为您使用的是FragmentActivity，所以应该使用SupportMapFragment而不是MapFragment（因为support API活动与support library的Fragment类一起工作，而不是与基本框架的Fragment类一起工作）。试着换一行
android:name="com.google.android.gms.maps.MapFragment"
对此
android:name="com.google.android.gms.maps.SupportMapFragment"
作为旁注，需要注意的是，您还应该使用AppCompatActivity而不是FragmentActivity。在将测试代码移植到我的生产应用程序后，我刚刚遇到了这条错误消息
就我而言，我忘记在清单文件中包含以下内容：
<meta-data
android:name="com.google.android.geo.API_KEY"
android:value="@string/google_maps_key" />
我很好地复制了字符串数据，但是我从头开始构建Mainfest，所以错过了googlemapsapi的关键信息
希望这能对有同样问题的人有所帮助。@剑客，你能再解释一下这是什么意思吗？[当我调用此活动时，映射_activity.xml文件，抛出此错误并停止。您说过，标记应该是'Fragment']？Regard为什么在片段中声明“xmlns:map”名称空间？你不需要它。您使用的Google Play Services库版本是什么？删除它。但结果还是一样。你使用的是什么库版本？设备安卓版本4.1.2，buildToolsVersion“23.0.2”，minsdk=16，类路径'com.google.gms:google服务：2.0.0-alpha3'，编译'com.google.Android.gms:play服务：8.3.0'和你的编译版本？
