Extract a part of text from textView and also make that text clickable?

Suraj Giri :

Suppose I have a string

String str =" Hello, @John how's going on"

Now I want to know., how to highlight the word @John and wanna make it clickable from Textview

Santanu Sur :

You can use clickable span in a spannable string like the following :-

SpannableString ss = new SpannableString(" Hello, @John how's going on");
ClickableSpan clickableSpan = new ClickableSpan() {
   @Override
   public void onClick(View textView) {
     //perform click operation
   }
   @Override
   public void updateDrawState(TextPaint ds) {

   }
};

ss.setSpan(clickableSpan, startIndex, endIndex, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);

yourTv.setText(ss);
yourTv.setMovementMethod(LinkMovementMethod.getInstance());
yourTv.setHighlightColor(Color.TRANSPARENT);

startIndex - is the index of J of word John in the full string

endIndex - is the index of n of the word John in the full string.

&& the onclick method will be triggered once john is clicked..

Edit

To extract the username John u can split the string and get it like this snippet :-

 String username = yourString.split("@")[1].split(" ")[0]; // this will extract john
