A simple case that could sacionar your problem would be, if clicking on the editText, it does these checks and validations for you

     editText1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            String editText1_text = editText1.getText().toString();
            String editText2_text = editText2.getText().toString();

            if(editText1_text == null && editText2_text == null)
                editText3_text.setVisibility(GONE);
            else if(editText1_text != null && editText2_text != null)
                editText3_text.setVisibility(VISIBLE);
        }

    });

editText2.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
        String editText1_text = editText1.getText().toString();
        String editText2_text = editText2.getText().toString();

        if(editText1_text == null && editText2_text == null)
            editText3_text.setVisibility(GONE);
        else if(editText1_text != null && editText2_text != null)
            editText3_text.setVisibility(VISIBLE);

        }
    });
