The code that deal with your file must be something like this (not compiled):

public void savefunc(){
    List myDate = new ArrayList(); //To store the formatted dates
    SimpleDateFormat thedate = new SimpleDateFormat("dd/MM/yyyy"); 
    Date d=new Date(); //the current date
    String sd = thedate.format(d); // sd contains "16/04/2013", the formatted date
    myDate.add(sd);

    double thedata=Double.parseDouble(value.getText().toString().trim());
    mydata.add(thedata);
    ...
    BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(fos));
    for (int i=0;i

Hope it helps.
