    EditText editField = (EditText)findViewById(R.id.weight_text_view);

In displayMessage method, write

result.setText(String.valueOf(message));

You set the calculated integer value to TextView but this value should be a String. If you set as an integer, it means you set the String Resource ID likes R.string.app_name.
