Question

I am using two textWatcher objects, which are assigned to two edittext. In my Android application, when one editTextPer is focusable, then I call the two methods

editTextHb.removeTextChangedListener(etTexthb);
editTextPer.addTextChangedListener(etTextper);

At this point, is etTexthb value null or not?

if(etTexthb  == null) {
  // etTexthb  is null do needfull
}
else {
//etTexthb is not null
}
