Use an enum to get a value from a string

Enum - Value From String

	private enum GravityExpandableText {
		LEFT(Gravity.LEFT), RIGHT(Gravity.RIGHT), CENTER(Gravity.CENTER);

		private final int mValue;

		GravityExpandableText(int value) {
			mValue = value;
		}

		public int getValue() {
			return mValue;
		}

		public static int getGravity(String gravity) {
			if (lowerCaseNameFor(LEFT).matches(gravity)) {
				return LEFT.getValue();
			} else if (lowerCaseNameFor(RIGHT).matches(gravity)) {
				return RIGHT.getValue();
			} else if (lowerCaseNameFor(CENTER).matches(gravity)) {
				return CENTER.getValue();
			}
			return Gravity.CENTER;
		}

		private static String lowerCaseNameFor(GravityExpandableText item) {
			return item.name().toLowerCase();
		}
