Add new line `\n' on TextView won't work

Question

I don't know why it doens't work. My TextView already set lines=6. String is set in code, like this :

address.setText((String) bundle.get("address"));

Above code still display \n as String not new line. bundle.get("address") is retrieved from .dat which is "line1\nline2" file store in asset But when i try this :

address.setText("line1\nline2");

this code works fine.

Any idea what gone wrong here? Thanks in advance

there is nothing wrong with the reading file, It shows the content, but won't display `\n` as new line, that's all. — HelmiB, Mar 07 '12 at 02:58

It's not really an answer i'm looking for, but i managed to do a bit of code to replace \n inside String (read from text file) to \n in code. here's my solution.

String seperator = "\n";  
String []tempText = a.split(seperator);

if (a.contains(seperator)){
        String b= "";
        for (String c : tempText)
            b +=c+"\n";
        b= b.substring(0, b.length()-2);
        address.setText(b);

    }else{
        address.setText((String) bundle.get("address"));

    }

Why don't you try giving an escape sequence for the . Please replace \n with \\n in the asset file, and see if it shows rightly now?

You probably have the slash encoded in your .dat file. Make sure that it's actually a newline character there.

I'm not quite understand what you mean. it displays : `line1\nline2` but display as it is, no separator line – HelmiB Mar 07 '12 at 03:00
What I mean is that if in your .dat file you have literally: line1\nline2, then that's what will come out (a slash then an n). \n is a special convention in Java (and some other languages) to represent a newline character.
