Java \\ n行分隔符不起作用

Question

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.

Answer 1

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.

Answer 2

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 .
