How do you underline a text in Android XML?

Question

If you are using a string resource xml file (supports HTML tags), it can be done using<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 tv = (TextView) view.findViewById(R.id.tv);
SpannableString content = new SpannableString("Content");
content.setSpan(new UnderlineSpan(), 0, content.length(), 0);
tv.setText(content);

Hope this helps

Use this:

TextView txt = (TextView) findViewById(R.id.Textview1);
txt.setPaintFlags(txt.getPaintFlags() | Paint.UNDERLINE_TEXT_FLAG);

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

If it does not work then

<resource>
<string name="your_string_here">This is an &lt;u>underline&lt;/u>.</string>

Because "<" could be a keyword at some time.

And for Displaying

TextView textView = (TextView) view.findViewById(R.id.textview);
textView.setText(Html.fromHtml(getString(R.string.your_string_here)));

First of all, go to String.xml file

you can add any HTML attributes like , italic or bold or underline here.

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

You can use the markup below, but note that if you set the textAllCaps to true the underline effect would be removed.

<resource>
    <string name="my_string_value">I am <u>underlined</u>.</string>
</resources>

Note

Using textAllCaps with a string (login_change_settings) that contains markup; the markup will be dropped by the caps conversion

The textAllCaps text transform will end up calling toString on the CharSequence, which has the net effect of removing any markup such as . This check looks for usages of strings containing markup that also specify textAllCaps=true.
