How to replace new line characters with actual new lines in a string in android?

I need to display a string which contains a lot of new line '\n'.These needs to be replaced with actual newlines in that string. How can I do that in android?

You can use this..

StringWriter stringWriter = new StringWriter();
PrintWriter writer = new PrintWriter(stringWriter, true);
writer.println("line1");
writer.println("line2");
writer.println("line3");
useString(stringWriter.toString());

line1, line2 and line3 will be printed in separate lines.

What seems to be happening is the string you receive from your database contains not the new line character, but rather the characters \ and n. The simplest fix is use simply the String.replace function to replace the character sequence \ n by the character \n like so:

String str = getStringWithFakeNewlines();
str.replace("\\n", "\n"); // The first backslash is doubled to find actual backslashes

you should concatenate the newline operator like:

String str = "This is testing" + "\n" + "How are you?";

you said from database you could split like:

String[] separated = str.split("\n");
separated[0]; // this will contain "This is testing"
separated[1]; // this will contain "How are you?"

and then concatenate them

String myString = "lots of \n new \n lines";
String newStringWithoutNewLines = myString.replace("\n", "");
