How do you underline a text in Android XML?

How do you underline a text in an XML file? I can't find an option in textStyle.

Solution 1:

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

Solution 2:

Use this:

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

Solution 3:

<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)));

Solution 4:

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>
