TextWatcher called even if text is set before adding the watcher

Question

public void onCreate(Bundle save         


        

Answer 1

Solution is to move your addTextChangedListener to onPostCreate method. all will be solved.

Answer 2

This definitely must be happening. You are setting text when savedinstanceState is not null (meaning your previous object states are saved).

I think that this happens because you added the TextWatcher to your EditText in the onCreate method, and next time onCreate gets called (e.g. after a configuration change) then it finds that the TextWatcher has already been added to the EditText.

If you want to check for this situation, put this before your condition:

if(savedInstanceState == null){
    Log.e("savedInstance state is null", "no text");
    et.setText("No text");
}

In this case, if you call setText on your EditText, then afterTextChanged(Editable s) will not be called.
