Answer 1

You can use DecimalFormat .

public class DecimalFormat extends NumberFormat

DecimalFormat is a concrete subclass of NumberFormat that formats decimal numbers. It has a variety of features designed to make it possible to parse and format numbers in any locale, including support for Western, Arabic, and Indic digits. It also supports different kinds of numbers, including integers (123), fixed-point numbers (123.4), scientific notation (1.23E4), percentages (12%), and currency amounts ($123). All of these can be localized.

Answer 2

You can use DecimalFormat before setting the value in textView

 texton.setText(setDotsDigit(score));

 public static String setDotsDigit(double value)
{
    return new DecimalFormat("###.###.###").format(value);
}

Answer 3

You should use DecimalFormat to format your score value first.

DecimalFormat formatter = new DecimalFormat("#,###.00")`;
String s = formatter.format(score);
texton = (TextView)findViewById(R.id.textcolumn);
texton.setText(s);
