You can try this:

Ibold.addTextChangedListener( new TextWatcher(){
                @Override
                public void onTextChanged( CharSequence txt, int start, int before, int count ) {
                    if (-1 != bold.indexOf("\n") ){


                       //here I detected new line
                        String editTextContent = Ibold.getText().toString();
                        editTextContent += "ADD YOUR TEXT HERE, IT WILL BE INSERTED AFTER THE LAST LINE BREAK";
                        Ibold.setText(editTextContent);


                    }
                }
