I'm saving some values to a txt file and after that i want to be able to show it in a dialog.All good,done that but though the values in the txt file are formated nicely,like this :

Aaaaaaaa       0.55        1
Bbbbb          1           2.2
CCCCCCCCC      3           0.22

When reading and setting them to a textview they get all messy like this :

Aaaaaaaa      0.55         1
Bbbbb       1           2.2
CCCCCCCCC      3       0.22 

My writting method :

FileOutputStream f = new FileOutputStream(file);
        PrintWriter pw = new PrintWriter(f);
        for (int n = 0; n < allpret.size() - 1; n++) {
            if (cant[n] != Float.toString(0)
                    && pret[n] != Float.toString(0)) {
                String myFormat = "%-20s %-5s %-5s%n";
                pw.println(String.format(myFormat, prod[n], cant[n],
                        pret[n]));

My reading method :

StringBuilder text = new StringBuilder();

            try {
                BufferedReader br = new BufferedReader(new FileReader(file));
                String line;

                while ((line = br.readLine()) != null) {
                    text.append(line);
                    text.append('\n');
                }
            } catch (IOException e) {

            }

Why does it ruin the amount of spaces and how can i fix this ? Thanks and have a good night !
