Methods

replaceUrlSpanWithAction

This method takes a SpannableStringBuilder object called title and a lambda function called urlAction as parameters. It replaces all instances of URLSpan within the title object with clickable spans that invoke the urlAction lambda function when clicked. The urlAction lambda function takes a String parameter and returns another lambda function that takes no parameters and performs a specific action.
