I have an EditText field in my application and have a TextWatcher associated with it. The afterTextChanged() event callback gets invoked even when the user does not tap on the EditText to edit it. I need to check if the user has edited the EditText or not and with the current code it always calls the afterTextChanged() method when I load the activity.

//TextWatcher
textwatcher_timestamp = new TextWatcher() {
            @Override
            public void beforeTextChanged(CharSequence s, int start, int count, int after) {

            }

            @Override
            public void onTextChanged(CharSequence s, int start, int before, int count) {

            }

            @Override
            public void afterTextChanged(Editable s) {

                String updatedText = s.toString();
                Log.v(TAG, updatedText);

            }
        };

        //Edit Text
        timestampereadback_text.addTextChangedListener(textwatcher_timestamp);

have u checked https://stackoverflow.com/questions/14327412/set-focus-on-edittext ? – abdulwasey20 Mar 01 '21 at 12:18
@Ticherhaz nope – Ian Bell Mar 01 '21 at 12:25
@abdulwasey20 I just checked, the editText.requestFocus(); does not work in this case – Ian Bell Mar 01 '21 at 12:28
@abdulwasey20 that is different question – Ian Bell Mar 01 '21 at 12:46
And you're not programmatically setting the text anywhere? – Henry Twist Mar 03 '21 at 01:10
@HenryTwist I am, when reload the activity, I am doing a setText on the EditText because I need to retrieve the value from my Rooms database and show it there on the EditText – Ian Bell Mar 03 '21 at 07:09
So surely that's what's triggering the change? – Henry Twist Mar 03 '21 at 10:19
@HenryTwist Yeah, that was what was triggering the change – Ian Bell Mar 03 '21 at 15:06
So your question is how to differentiate in the listener between programmatic changes and user triggered ones? – Henry Twist Mar 03 '21 at 15:13
@HenryTwist Yeah, is there a way to do it? – Ian Bell Mar 03 '21 at 15:14
@HenryTwist Yeah, that does! Thank your :) – Ian Bell Mar 03 '21 at 15:17
