In order to change the text color of a TextView, you could use the following code:

foodLabel.setTextColor(Color.RED);
drinkLabel.setTextColor(Color.YELLOW);

Between the brackets of the setTextColor function you could also use the following to parse a hexadecimal color:

// This would become red
foodLabel.setTextColor(Color.parseColor("#FF0000"));
// And this is also red!
foodLabel.setTextColor(Color.rgb(255, 0, 0));

I hope I answered your question correctly.
