我有一个应用程序，它收集 wifi 和蜂窝数据使用情况并通过 SMS 将其作为数据字符串发送 - 但是我需要一些帮助来将它发送的字符串修改为正确的格式

现在出现的样子：

USI;1;3056090866;06/16/58/06/24/13;CN25.48,WN86.957;CN34.931,WN16.656

我希望它以以下方式发送：（第二个 CN 和 WN 更改为 CO 和 WO）

USI;1;3056090866;06/16/58/06/24/13;CN25.48,WN86.957;CO34.931,WO16.656

如何实现？我尝试使用：

info = info.replace("CN", "CN", "CN, "CO"");

和

info = info.replace("CN", "CO"");

但两者都没有给出预期的输出

附言

建议的任何方法都需要考虑此数据字符串中的数值变化 - 但字母 CN 和 WN（蜂窝网络和无线网络）保持不变 - 我只需将输出中的第二个 CN 和 WN 更改为WO和CO

试试这个代码->

String str = "USI;1;3056090866;06/16/58/06/24/13;CN25.48,WN86.957;CN34.931,WN16.656";
StringBuilder b = new StringBuilder(str);
b.replace(str.lastIndexOf("CN") - 1, str.lastIndexOf("CN") + 2, "CO" );
b.replace(str.lastIndexOf("WN") - 1, str.lastIndexOf("WN") + 2, "WO" );
str = b.toString();

它会工作..

Amani，我同意 Vishal 上面的回答会起作用——你只需要用你自己的数据替换他在顶部初始化的 String str 。然后通过他发布的后四行代码运行它。

在这个阶段，我们都假设您的数据字符串只能包含“随机”部分中的数字，并且文字 CN 和 WO 将恰好出现两次。您在问题中的帖子脚本暗示了这一点。如果它们可以更频繁地出现，则此解决方案将始终替换最后出现的情况。如果它们出现的频率较低，则此解决方案将引发异常（即它会崩溃）。
