我有一个字符串

字符串时间= 1小时37分钟如何在Android中将此时间转换为1:37:00格式？

Answer 1

1）第一步，从字符串中删除空间（字符串=“ 1小时37分钟”）

   text = string.replace(" ", "");

2）第二步，将小时替换为“：”，将分钟替换为“：00”

text = text.replace("hour",":");
      text = text.replace("minutes",":00");

Answer 2

我想您必须编写一个函数，将字符串格式化为所需的格式。您的功能应如下所示：

public static String formatTime(String inputTime)
{
String result = inputTime.replace(" ","");
result = result.replace("hours",":").replace("hour",":").replace("minutes","").replace("minute","");
String[] resultAux = result.split(":"); //First position will be hours, second position will be minutes

for(int i=0; i<resultAux.length; i++)
{
    if(resultAux[i].length() == 1)
    {
        resultAux[i] = "0" + resultAux[i]; //If we have 1 character in minutes we put the 0
    }
}

return String.join(":",resultAux) + ":00"; //Due to in your example you don't mention that you can have miliseconds we just put the miliseconds at the end


}

当然，您将这样调用函数：

System.out.println("result is: " + formatTime("2 hours 37 minutes"));

如何转换00:00:00格式的字符串时间值？
