how to clear the TextView when reverting back to the same activity?

I have a TextView that displays an error message in the login page of my activity. I do not know how to clear its value when i come back to this activity. i used editText.setText("") for an EditText field. but when i tried to use this for my TextView it showed a NullPointerException What could be used here ? 

error = (TextView) findViewById(R.id.errorPopUp);
