Question

我有一个Java项目，其中有一个Constants类来组织我的常量：

/** This is my java constants file in java**/

public class Constants {
    public static final String LOWER_GROUND_FLOOR = "LG";
    public static final String GROUND_FLOOR = "G";
    public static final String FIRST_FLOOR = "1";
    public static final String SECOND_FLOOR = "2";
    public static final String THIRD_FLOOR = "3";
    public static final String THIS_KIOSK_ID = "currentFloorIndex";
    public static final String EXPIRY = "cacheExpiry";
    public static String third_floor_small_map_path = "map/abc.png";
}

如何在Kotlin中创建类似的常量文件？

Answer 1

如果要像在Java中创建public static final一样在kotlin中创建一个公共常量，则可以按以下步骤创建它。

companion object {

     const val MY_CONSTANT = "Constants"

}
