使用Java从字符串中提取两个数字

Question

  

“跟踪信息纬度：3.9574667经度：7.448882167”

消息字符串的结构不会改变，只是数字会改变。

Answer 1

为此，您甚至不需要正则表达式。只需拆分String并调用正确的索引：

String latLongString = "Tracking info Latitude: 3.9574667 Longitude: 7.44882167"; //yours obviously won't be hardcoded
String[] split = latLongString.split(" ");
String lat = split[3];
String lon = split[5];
