Android 错误编号格式异常
当我点击我的操作按钮时，我得到一个错误。我从一个名为GPSTracker的类中获取两个坐标，然后使用getLatitude和getLongitude方法返回我的类。如果单击“操作”按钮，则会出现以下错误：Android 错误编号格式异常,android,gps,runtime-error,Android,Gps,Runtime Error,当我点击我的操作按钮时，我得到一个错误。我从一个名为GPSTracker的类中获取两个坐标，然后使用getLatitude和getLongitude方法返回我的类。如果单击“操作”按钮，则会出现以下错误： 09-12 17:07:46.898 24575-24575/?

}问题出在您的第177行。您在那里得到了逗号，因此需要将其替换为.dot以将其解析为双精度。 换线
double distanzaFilaQuattro = Double.parseDouble(df1.format(distanzaQuattro));
为什么你的双精度密码之间有逗号：4782877,28-请正确查看日志。。。您没有使用正确的值来划分我的位置坐标。例如，41.001254和14.003235。我认为您正在一起解析它们。。like:Double.parseDoublelat，long；这就是为什么你会这样做的原因。GetFila是一种从类GPSTrackerAfter获取坐标的方法，设置Lat，并将其替换为aDouble.parsedouble.p.替换'，'，'@苏拉伯斯这条线？double distanzaFilaQuattro=double.parseDoubledf1.formatdistanzaQuattro；好啊试着像这样打印结果；和Log.edistanzaQuattro，+distanzaQuattro；在这几行之前。。。double distanzaFilaTre=double.parseDoubledf1.formatdistanzaTre；double distanzaFilaQuattro=double.parseDoubledf1.formatdistanzaQuattro；兄弟。。。尝试将行更改为double distanzaFilaQuattro=double.parseDoubledf1.formatdistanzaQuattro.replace，，。；
double distanzaFilaQuattro = Double.parseDouble((df1.format(distanzaQuattro)).replace(",","."));
