String s="Item 1: 1.5 - 2.5"//s=spinner.getItemAt(i)
String newS[]=s.split(":");//newS[0]="Item 1" and newS[1]="1.5-2.5"
String newS2[]=newS[1].split("-");//

Double d1=Double.parseDouble(newS2[0]);
Double d2=Double.parseDouble(newS2[1]);
Double avg=(d1+d2)/2;

String str = "Item 1: 1.5 - 2.5";
String[] strs = str.split(":");

String numberStr = (strs[strs.length - 1]).trim();
String[] numbers = numberStr.split("-");

float sum = 0f;
for (int i = 0; i < numbers.length; i++) {
    sum = sum + Float.valueOf(numbers[i]).floatValue();
}
//Here, get the average of the two numbers
float result = sum / (numbers.length);
