错误NumberFormatException Android

当我点击我的操作按钮时出现错误。我从一个名为“GPSTracker”的类中获取两个坐标，然后使用方法“getLatitude”和“getLongitude”返回到我的类。如果我点击我的行动按钮，我得到这个错误：错误NumberFormatException Android

，如果我做的运行在模拟器上genymotion应用，没事！如果我使用我的三星平板电脑，我会收到错误消息。我该如何解决？

为什么有逗号的双重之间：4782877,28 ---看日志正常。 – Tauqir

把代码放在这里......你没有使用正确的值来解析 –

是我的位置的坐标。例如41.001254和14.003235。 – Marco

getFila（）是从类GPSTracker – Marco

获取坐标后的方法设置Lat和Long使这个取代了，为a。：'Double.parseDouble（p.replace（'，'，'。'））;' –

嘿告诉我你的片段没有177线。 –

问题是在你的行中没有177.you越来越逗号那里，所以你需要将其替换（。）点将其解析为双精度型。行

double distanzaFilaQuattro = Double.parseDouble(df1.format(distanzaQuattro));

更改为

double distanzaFilaQuattro = Double.parseDouble((df1.format(distanzaQuattro)).replace(",","."));
