android - java.lang.NumberFormatException : For input string: "-0.‎086167157" 异常

Question

所以我已经为此苦苦挣扎了一段时间，对我来说，我看不出为什么 -0. 086167157 不是有效的 double 值。我只是想将从 API 调用返回的字符串值转换为 double 值(经度值)

这是错误信息:

我正在使用 Gson 进行网络调用改造

您的字符串在句号之后有一个不可见的非打印字符。复制并粘贴到十六进制转储，您会看到:

00000000  2d 30 2e e2 80 8e 30 38  36 31 36 37 31 35 37 |-0....086167157|

好像是一个left-to-right mark

解决方法:在API中修复。客户端没有理由过滤输入中的垃圾数字。
