You need to assign the foodLabel and drinkLabel to the specific TextView. So it should be as follows:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_meal);

    foodLabel = (TextView) findViewById(R.id.foodTextView);
    drinkLabel = (TextView) findViewById(R.id.drinkTextView);
    RelativeLayout mealLayout = (RelativeLayout) findViewById(R.id.mealLayout);
    mealLayout.setBackgroundColor(Color.GREEN);
    foodLabel.setTextColor(Color.BLUE);
    drinkLabel.setTextColor(Color.GRAY);
}
