How do you underline a text in Android XML?

Question

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

Another way to do it, is creating a custom component extending TextView. It's good for cases where you need to have multiple underlined TextViews.

Here's the code for the component:

package com.myapp.components;

import android.content.Context;
import android.support.v7.widget.AppCompatTextView;
import android.text.SpannableString;
import android.text.style.UnderlineSpan;
import android.util.AttributeSet;

public class LinkTextView extends AppCompatTextView {
    public LinkTextView(Context context) {
        this(context, null);
    }

    public LinkTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public void setText(CharSequence text, BufferType type) {
        SpannableString content = new SpannableString(text);
        content.setSpan(new UnderlineSpan(), 0, content.length(), 0);

        super.setText(content, type);
    }
}

And how to use it in xml:
