Why my Spannable text edit is not getting applied?

I am new to android, i have a textView and i am doing like this to setText(There is only one text box)

Spannable wordtoSpan = new SpannableString(message);
        wordtoSpan.setSpan(new ForegroundColorSpan(Color.GREEN),0,message.length(),Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
        wordtoSpan.setSpan(new UnderlineSpan(),0,message.length(),0);
        tv.setText(wordtoSpan);
        tv.setMovementMethod(new ScrollingMovementMethod());
       // Log.v(TAG, "hi");
        while(line != null) {
            if(message.equals(line)) {
                Log.v(TAG, "hi");
                while(!("end".equals(line))) {
                    Log.v(TAG, "hello");
                    line = reader.readLine();
                    tv.setText(tv.getText() +" \n" + line);
                }
            }
            line = reader.readLine();
        }

The Spannable string is not getting applied. But when i remove second setText then the spannable string is applied How android handles the text view.

In setText is checked if the provided CharSequence is an instance of Spanned

getText() is returning a CharSequence which might be an instance of Spanned.

But if you do + " \n" + line it gets converted to a String, so the stuff you have in Spannable will not be applied.
