Get Editable id in afterTextChanged event

Question

I have an Activity that extends TextWatcher to detect changes in certain EditTexts, so it implements:

public void afterTextChanged(Editable s)

Answer 1

There's one method to implement this without creating a TextWatcher object for every EditText, but I wouldn't use it:

protected void onCreate(Bundle savedInstanceState) {
    // initialization...

    EditText edit1 = findViewById(R.id.edit1);
    edit1.addTextChangedListener(this);
    EditText edit2 = findViewById(R.id.edit1);
    edit2.addTextChangedListener(this);
}

private static CharSequence makeInitialString(EditText edit) {
    SpannableStringBuilder builder = new SpannableStringBuilder();
    builder.setSpan(edit, 0, 0, Spanned.SPAN_MARK_MARK);
    return builder;
}

public void afterTextChanged(Editable s) {
    EditText[] edits = s.getSpans( 0, s.length(), EditText.class );
    if (edits.length != 1) {
        // this mustn't happen
    }

    // here's changed EditText
    EditText edit = edits[0];
}
