writing some characters like '<' in an xml file

问题

since the beginning of my programmation, I used some special character like "<-", ""<<" im my string.xml in Eclipse while developping for Android.

All worked fine for one year, but today, i just wanted to make some minor changes and began to edit my xml files.

I get now compilation error on these characters because eclipse believe it's part of the xml blocks.

Any idea on how I could add this symbol "<" in my xml files?

Thank a lot.

I stumbled upon this question, as I use HTML markup in my strings.

If you refer to the Android String Resources documentation, in the section: "Styling with HTML markup" you will see that in strings.xml, you need to use &amplt; for an opening bracket, but you can safely use backslash and a closing bracket. For example:

<b>Text</b>

can be written as:

<b>Text</b>

in your strings.xml.

If using this HTML string in your code, you can use:

Html.fromHtml( getResources().getString(R.string.yourHTMLString ) 

and the output will be your bold string!
