Sound like you're trying to do this, except instead of 2 you want 4: Android Development: How To Use onKeyUp?

You cannot use an OnClickListener, you need a TextWatcher. See this answer: https://stackoverflow.com/a/11134227/3673616

you can put your code inside TextWatcher like this:

editText1_id.addTextChangedListener(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) {
            if (editText1_id.getText().toString().isEmpty()) {
                editText1_id.setBackgroundResource(R.drawable.buttonshap_red_outline);
            }else if (editText1_id.length() < 4){
                editText1_id.setBackgroundResource(R.drawable.buttonshap_red_outline);
            }else if (editText1_id.length() == 4) {
                editText1_id.setBackgroundResource(R.drawable.insert_frame);
            } else {
                editText1_id.setBackgroundResource(R.drawable.insert_frame);
            }
        }
    });

as you can see you can add addTextChangedListener to each EditText. it has three listener that help you to notice when user start typing
