java--枚举使用小例

一个枚举的使用小例子：

public class CommonLoadingBar {public static enum Type {NO_DIALOG, SHOW_LOADING, SHOW_NET_EXCEPTION, SHOW_NO_DATA, NORMAL_FEES}private Type mLoadingType = null;public CommonLoadingBar(View view) {mLoadingType = Type.NO_DIALOG;}public void showViewType(Type type) {if (type != Type.SHOW_LOADING && type != Type.SHOW_NET_EXCEPTION&& type != Type.SHOW_NO_DATA && type != Type.NORMAL_FEES) {return;}mLoadingType = type;if (mView != null && mView.getVisibility() != View.VISIBLE) {mView.setVisibility(View.VISIBLE);}if (type == Type.SHOW_LOADING) {showLoadingDialog();} else if (type == Type.SHOW_NET_EXCEPTION) {showNetException();} else if (type == Type.SHOW_NO_DATA) {showNoData();} else if (type == Type.NORMAL_FEES) {showNormalFees();}}}
