Reading from txt ruins formatting
- by Sorin Grecu
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 !
