如何更改.csv数据中的数字格式Kotlin

问题描述

我从传感器接收数据并将其保存在.csv文件中。但我的格式像0.234.234.234.123.5434
我需要的是这样的格式0,23452342234234234

private fun formatRowData(x: Float,y: Float,z: Float,length: Double,angle: Double): String {
    return String.format(
           "${SimpleDateFormat("H:m:s:SSS")
                .format(today.time)};$x;${y};${z};${length};${angle}",Locale.GERMANY
    )
}

解决方法

尝试一下：

<div class="container">
  <div class="block">
    <span>some data here</span>
  </div>
  <div class="block">
    <span>some data here</span>
  </div>
  <div class="advanced-items">
    <span>1. item</span>
    <span>2. item</span>
    <span>3. item</span>
    <!-- more items here -->
  </div>
</div>

输出：

var value:String  ="0.234.234.234.123.5434"
value = value.replaceFirst(".",",")
value = value.replace(".","")

println(" : "+value)
