Let's continue to add color to MealActivity. In the onCreate() method, set the text color of foodLabel to Color.BLUE. Then set the text color of drinkLabel to Color.GRAY.

MealActivity.java 
public class MealActivity extends Activity {

    public TextView foodLabel;
    public TextView drinkLabel;

    @Override
    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.setBackgroundColor(Color.BLUE);
      drinkLabel.setTextColor(Color.GRAY);
    }
}

Kourosh is correct! Try this

foodLabel.setTextColor(Color.BLUE);

instead of this

foodLabel.setBackgroundColor(Color.BLUE);

It's wrong! I don't know why! Please help:

public class MealActivity extends Activity {

public TextView foodLabel;
public TextView drinkLabel;

@Override
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.setTextColoe(Color.GRAY);
}

}
