When building a string, you can create newlines like so:
"This is the first line \n\n And this is the second line";
So, when running this portion of code all works well on the Android Emulator:
TextView newsTextArea = (TextView) view.findViewById(R.id.newsTextView);
newsTextArea.setText("Hello \n\n Whats up");
However, I have downloaded and parsed JSON from a web service we have created, and I have stored what I want in a variable like so:
GlobalSettings globalSettings = new GlobalSettings();
String newsText = globalSettings.getNews();
So the variable newsText
equals a string, which lets say for arguments sake here is "Hello, this has two lines. \\n\\n Welcome to the test"
.
When I run the above TextView
code like this, it outputs it with the \\n\\n
as literal characters.
newsTextArea.setText(newsText);
How can it be done so that the variable newsText
keeps the formatting?
im a good guesser..lol well there may be soo many reasons that i think
1. newsTextArea.setSingleLine(false);
2. newsTextArea.setMinLines(2); or newsTextArea.setMaxLines(50);//any figure
3. String newsText = globalSettings.getNews().replace("\\\n", System.getProperty("line.separator"));
4. String newsText = globalSettings.getNews().toString();
play with these methods and see if one works for ya or two lol

There are great chances that your JSON WS returns the literate sequence \\n
as its output. Not the line-feed character ( <LF>
) as you expected it.
At this point you probably have two options:
\\
will pop out in your data). Maybe it is time to post an other question, this time about your JSON web service ?
It is likely that wherever that text comes from in the first place, the backslash is getting escaped. For example, it may be coming from a hard-coded constant in your service, entered into a form by a human and then validated, or etc.
Look at your JSON in its raw format before it is parsed. The JSON spec says that a single backslash followed by n means the newline character. If it looks like ["Hello, this has two lines. \\n\\n Welcome to the test"]
then you should be good, because the JSON parser should interpret the newline characters correctly. However, if it looks like this: ["Hello, this has two lines. \\\\n\\\\n Welcome to the test"]
, then the backslash character is being escaped, not the n.
