Android: format string and add bold style

From the official documentation:

Sometimes you may want to create a styled text resource that is also used as a format string. Normally, this won't work because the String.format(String, Object...) method will strip all the style information from the string. The work-around to this is to write the HTML tags with escaped entities, which are then recovered with fromHtml(String), after the formatting takes place.

You need to HTML-escape the opening bracket of html tags, when inserting it in any xml resource file.

<string name="region">&lt;b>Region:&lt;/b> %1$s</string>

Here's how you can do that in xml:

<string name="region"><![CDATA[<b>Region:</b> %1$s]]></string>

And the java code:

String str = getString(R.string.action_about_msg, "France");
tvRegion.setText(Html.fromHtml(str));

You can use HTML text directly in Html.fromHtml() method.. try this way..

tvRegion.setText(Html.fromHtml("<b>" + yourtext+ "</b>" + "Other text.."));

with this you can style your string with HTML tags.. as you want..
