请提供帮助：android.view.InflateException:二进制XML文件行#3:错误为类com.google.android.maps.MapView充气

我编写了Get Point应用程序（）来存储GPS坐标，并导出一个KML文件，以便在Google Earth中打开。创建该应用程序是因为我需要学习Android平台

因为我是Android新手，如果我问了一个愚蠢的问题，请原谅我。：）

Google标记的开发者控制台显示有一个错误，我自己无法在emulator中重现（使用Google APU、Galaxy S或Galaxy 5:(

错误消息是：android.view.InflateException:Binary XML文件行#3:error-inflating class com.google.android.maps.MapView

我正在寻找解决方案，但找不到答案：(

任何帮助都将不胜感激。

问题的核心在于堆栈跟踪的最底层：

地图视图只能在MapActivity的实例内部创建。

基本上，无论出于何种原因，膨胀都是从您的PointView外部发生的

jv.android.getpoint.ListaCordAdapter是您的类之一吗？从堆栈跟踪中可以看出，这是试图扩大布局的类。如果这个类是您的，它是否扩展了MapActivity？

我通过扩展MapActivity来修复它，而不是通过调用MapView的Activity类中的活动来修复它结束MapActivity而不是调用MapView的Activity类中的Activity
您的
default.properties
文件中有什么？您的
default.properties
文件中有什么？谢谢。我添加了ListAcoorAdapter类和default.properties值。ListAcoorAdapter只是ListView的新适配器，而不是MapView。我看到了这在堆栈中，但我不明白为什么？：（有没有可能得到完整的堆栈跟踪（没有“…43更多”）？可能还有另一个线索。该跟踪来自谷歌市场。我无法在我的设备/计算机中重现错误：（谢谢。我添加了ListaCordAdapter类和Default.Properties值。ListaCordAdapter只是ListView的一个新适配器，而不是MapView。我在堆栈中看到了这一点，但我不明白为什么？：（有没有可能获得完整的堆栈跟踪（没有“…43更多”）？可能还有另一个线索。这个线索来自谷歌市场。我无法在我的设备/计算机中重现错误：(
