问题描述

我有收集WiFi和蜂窝数据使用和将其作为通过SMS数据串的应用程序 - 但是我需要一点帮助修改它送入正确的格式字符串

的方式,现在看来:

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

我想它以下述方式发送的方式:(与第二CN和WN变为CO和WO)

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

这又如何实现呢?我已经尝试使用:

 信息= info.replace(CN,CN,CNCO);

 信息= info.replace(CN,CO);

但既不是给予期望的输出

P.S。

无论采用哪种方式,建议需要考虑到这串数据变化的数值 - 但字母CN和WN(蜂窝网络和无线网络)保持不变 - 我只是需要改变第二CN和WN中输出以WO和CO

解决方案

试试这个code - >

 字符串str =USI; 1; 3056090866; 06/16/58/06/24/13; CN25.48,WN86.957; CN34.931,WN16.656 ;
StringBuilder的B =新的StringBuilder(STR);
b.replace(str.lastIndexOf(CN) - 1,str.lastIndexOf(CN)+ 2,CO);
b.replace(str.lastIndexOf(WN) - 1,str.lastIndexOf(WN)+ 2,WO);
海峡= b.toString();

这将工作..

I have an application which gathers wifi and cellular data usage and sends it as a string of data via SMS - however I need a bit of help modifying the string it sends into the correct format

The way it appears now:

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

The way I would like it to send in the following manner: (with the second CN and WN changed to CO and WO)

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

How can this be accomplished? I've attempted to use:

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

and

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

but neither is giving the expected output

P.S.

Whatever method is suggested needs to take into account the numeric values in this string of data change - but the letters CN and WN (Cellular Network and Wireless network) stay the same - I simply need to change the 2nd CN and WN in the output to WO and CO

解决方案

Try this code->

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();

It will work..

这篇关于信息= info.replace(QUOT; CN&QUOT;,&QUOT; CN&QUOT;,&QUOT; CN,QUOT; CO&QUOT;&QUOT;);不能按预期的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持IT屋!
