Question

I have a String in TextView and I want to Linkify a substring from that string. for example:

click here to know more.

I’m getting the string dynamically. So i have to search if it has click here and convert that to link .How can I linkify “click here”.

Answer 1

To find a pattern inside a text and replace it, use this:

Pattern p = Pattern.compile("click here");
Matcher m = p.matcher("for more info, click here");
StringBuffer sb = new StringBuffer();
boolean result = m.find();
while(result) {
    m.appendReplacement(sb, "<a href=\"www.mywebsite.com\">click here</a>");
    result = m.find();
}
m.appendTail(sb);
String strWithLink = sb.toString();

yourTextView.setText(Html.fromHtml(strWithLink));
yourTextView.setMovementMethod(LinkMovementMethod.getInstance())

This code will search inside your string and replaces all “click here” with a link.

And at the end, do NOT add android:autoLink=”web” to you XML resource (section TextView), otherwise A-tags are not rendered correctly and are not clickable any longer.
