Line Break in XML formatting?

问题

when editing a String in XML I need to add line breaks. And I wanted to ask what is the RIGHT form when programming for android? Because   works but ECLIPSE marks the area as problematic. If I check out suggestions Eclipse tells me that I shall add a end tag  - IF I add that the line break dissapears...

So the one works but is marked as problematic, the other works not but Eclipse tells me its ok..

What form shall I use?

回答1:

Use \n for a line break and \t if you want to insert a tab.

You can also use some XML tags for basic formatting:  for bold text,  for italics, and  for underlined text.

Other formatting options are shown in this article on the Android Developers' site:
https://developer.android.com/guide/topics/resources/string-resource.html#FormattingAndStyling

回答2:

If you are refering to res strings, use CDATA with \n.

<string name="about">
    <![CDATA[

</string>

Also you can add instead of \n.

And then you can add text to TexView:

articleTextView.setText(Html.fromHtml(textForTextView));

Take note: I have seen other posts that say 
 will give you a paragraph break, which oddly enough works in the Android xml String.xml file, but will NOT show up in a device when testing (no breaks at all show up). Therefore, the \n shows up on both.

Here is what I use when I don't have access to the source string, e.g. for downloaded HTML:

// replace newlines with <br>
public static String replaceNewlinesWithBreaks(String source) {
    return source != null ? source.replaceAll("(?:\n|\r\n)","<br>") : "";
}

For XML you should probably edit that to replace with   instead.

Example of its use in a function (additional calls removed for clarity):

// remove HTML tags but preserve supported HTML text styling (if there is any)
public static CharSequence getStyledTextFromHtml(String source) {
    return android.text.Html.fromHtml(replaceNewlinesWithBreaks(source));
}

...and a further example:

textView.setText(getStyledTextFromHtml(someString));
