Remove underline from links in TextView - Android

You can do it in code by finding and replacing the URLSpan instances with versions that don't underline. After you call Linkify.addLinks(), call the function stripUnderlines() pasted below on each of your TextViews:

    private void stripUnderlines(TextView textView) {
        Spannable s = new SpannableString(textView.getText());
        URLSpan[] spans = s.getSpans(0, s.length(), URLSpan.class);
        for (URLSpan span: spans) {
            int start = s.getSpanStart(span);
            int end = s.getSpanEnd(span);
            s.removeSpan(span);
            span = new URLSpanNoUnderline(span.getURL());
            s.setSpan(span, start, end, 0);
        }
        textView.setText(s);
    }

This requires a customized version of URLSpan which doesn't enable the TextPaint's "underline" property:

    private class URLSpanNoUnderline extends URLSpan {
        public URLSpanNoUnderline(String url) {
            super(url);
        }
        @Override public void updateDrawState(TextPaint ds) {
            super.updateDrawState(ds);
            ds.setUnderlineText(false);
        }
    }

Here is Kotlin extension function:

fun TextView.removeLinksUnderline() {
    val spannable = SpannableString(text)
    for (u in spannable.getSpans(0, spannable.length, URLSpan::class.java)) {
        spannable.setSpan(object : URLSpan(u.url) {
            override fun updateDrawState(ds: TextPaint) {
                super.updateDrawState(ds)
                ds.isUnderlineText = false
            }
        }, spannable.getSpanStart(u), spannable.getSpanEnd(u), 0)
    }
    text = spannable
}

Usage:

txtView.removeLinksUnderline()    

Given a textView and content:

TextView textView = (TextView) findViewById(R.id.your_text_view_id);
String content = "your <a href='http://some.url'>html</a> content";

Here is a concise way to remove underlines from hyperlinks:

Spannable s = (Spannable) Html.fromHtml(content);
for (URLSpan u: s.getSpans(0, s.length(), URLSpan.class)) {
    s.setSpan(new UnderlineSpan() {
        public void updateDrawState(TextPaint tp) {
            tp.setUnderlineText(false);
        }
    }, s.getSpanStart(u), s.getSpanEnd(u), 0);
}
textView.setText(s);

This is based on the approach suggested by robUx4.

In order to make the links clickable you also need to call:

textView.setMovementMethod(LinkMovementMethod.getInstance());

UnderlineSpan already exists, but can only set the underline.

Another solution is to add a no underline span on each existing URLSpan. Thus the underline state is disabled just before painting. This way you keep your URLSpan (possibly custom) classes and all other styles set elsewhere.

public class NoUnderlineSpan extends UnderlineSpan {
    public NoUnderlineSpan() {}

    public NoUnderlineSpan(Parcel src) {}

    @Override
    public void updateDrawState(TextPaint ds) {
        ds.setUnderlineText(false);
    }
}

Here is how you set it without removing the existing URLSpan object:

URLSpan[] spans = s.getSpans(0, s.length(), URLSpan.class);
for (URLSpan span: spans) {
    int start = s.getSpanStart(span);
    int end = s.getSpanEnd(span);
    NoUnderlineSpan noUnderline = new NoUnderlineSpan();
    s.setSpan(noUnderline, start, end, 0);
}
