Copying text from one EditText box to another in t

Question

I am building an application to convert Latitude and Longitudes between various formats. My layout is complete but my current challenge is this:

For the Degree values, as the user enters a value in EditText1, I want it to replicate in EditText2 as they are typing, real-time, character for character. I have beat myself up trying OnTouchListener, onKeyboardActionListener, etc.

Later, I will perform calculations on the Minutes, Seconds, and decimal portions as they are typed in. Since the Degree field does not require calculations I am just trying to replicate the users value across multiple EditText boxes for now.

SUMMARY: Capture the characters in EditText1 as they are typed Place EditText1 captured characters into EditText2 on the fly.

Any help would be greatly appreciated.

I haven't tested, but I found addTextChangedListener():

EditText firstEditText = (EditText)findViewById(R.id.firstEditText);
firstEditText.addTextChangedListener(new TextWatcher(){
    public void afterTextChanged(Editable s){
        String c = s.toString(); // read Content
        ((EditText)findViewById(R.id.secondEditText)).setText(c); // copy to #2
    }
    public void beforeTextChanged(CharSequence s, int start, int count, int after){ }
    public void onTextChanged(CharSequence s, int start, int before, int count){ }
});
