Can I underline text in an Android layout?

It can be achieved if you are using a string resource xml file, which supports HTML tags like <b></b>, <i></i> and <u></u>.

<resources>    <string name="your_string_here">This is an <u>underline</u>.</string></resources>

If you want to underline something from code use:

TextView textView = (TextView) view.findViewById(R.id.textview);SpannableString content = new SpannableString("Content");content.setSpan(new UnderlineSpan(), 0, content.length(), 0);textView.setText(content);

You can try with

textview.setPaintFlags(textview.getPaintFlags() |   Paint.UNDERLINE_TEXT_FLAG);

The "accepted" answer above does NOT work (when you try to use the string like textView.setText(Html.fromHtml(String.format(getString(...), ...))).

As stated in the documentations you must escape (html entity encoded) opening bracket of the inner tags with <, e.g. result should look like:

<resource>    <string name="your_string_here">This is an <u>underline</u>.</string></resources>

Then in your code you can set the text with:

TextView textView = (TextView) view.findViewById(R.id.textview);textView.setText(Html.fromHtml(String.format(getString(R.string.my_string), ...)));
