Java \n line separator not working

I am creating an application that has a data log. I build up this data with a string that I add to everytime the application receives data and then display it in an edittext box.

The problem I am having is that it will display the data but without the new lines.

A basic example of the code:

String logText;
EditText etLog;

logText = data + "\n" + logText;
etLog.setText(logText);

I know that I can use nl = System.getProperty("line.separator"); to get a new line but I'm puzzled as to why "\n" is not working when I've used it in different apps I've created before.

Not overly keen on answering my own question but I solved it by changing the inputType of my EditText to textMultiLine in my xml code.
xml code:

android:inputType="textMultiLine"


Allows the EditText to make use of "\n" within a string.

Usually the problem arises because of a particular programs preferences. The \n(new line feed) is one possibility, but there is also \r aka carriage return.

The two are essentially the same, just that there's a standardisation issue. Java uses both for compatibility. Try one, the other, both. Usually one will work.

For editText, I believe its \r\n.
