Answer 1

you can use this code in many ways in your program, you give it a string and it separate each three from right and place space there.

private String Spacer(String number){
    StringBuilder strB = new StringBuilder();
    strB.append(number);
    int Three = 0;

    for(int i=number.length();i>0;i--){
        Three++;
        if(Three == 3){
            strB.insert(i-1, " ");
            Three = 0;
        }
    }
    return strB.toString();
}// end Spacer()

u can change it a bit and use it ontextchangelistener. good luck
