-1

所以我的朋友创建了这个枚举，我想缩短它。我想缩短字符串中的每个文件路径并引用它String pokemonPath = "Pictures/Menu/MainMenu/";，然后就像pokePath +" Cosmet.png但我不确定如何实现它。另外，如果有人对如何缩短它有任何想法，我也很想听听。ALos 它在它自己的类文件中，因此将常量放在顶部将无法正常工作，它给我一个错误。

我并没有真正使用枚举，所以我不知道如何有效地使用它们。

这是他的代码

你如何做将取决于你想要实现什么。

如果您想防止在路径发生变化时需要在多个地方替换路径，那么使用String常量是一个合理的想法。

就像是...

public interface PathConstants {

    protected static final String SPRITES_PATH = "Pictures/Sprites";
    protected static final String SPRITES_MISC_PATH = SPRITES_PATH + "/Misc";
    protected static final String POKEMON_SPRITES_PATH = SPRITES_PATH + "/Pokemon";
    protected static final String POKEMONB_SPRITES_PATH = SPRITES_PATH + "/PokemonB";
    protected static final String STARTERS_MENU_PATH = "Pictures/Menu/Starters";
    protected static final String SPRITES_BATTLE_PATH = SPRITES_PATH + "/Battle";
    protected static final String MENU_BATTLE_PATH = SPRITES_BATTLE_PATH + "/BattleMenu";

}

然后你应该能够做类似的事情......

public enum Images {
    Cosmet(PathConstants.SPRITES_PATH + "/Cosmet.png"), CosmetB(
           PathConstants.POKEMONB_SPRITES_PATH + "/CosmetB.png"), CosmetStart(
           PathConstants.STARTERS_MENU_PATH + "/CosmetStart.png"),

    Tykepol(PathConstants.POKEMON_SPRITES_PATH + "/Tykepol.png"), TykepolB(
            PathConstants.POKEMONB_SPRITES_PATH + "/TykepolB.png"), TykepolStart(
            PathConstants.STARTERS_MENU_PATH + "/TykepolStart.png"),

    Embite(PathConstants.POKEMON_SPRITES_PATH + "/Embite.png"), EmbiteB(
           PathConstants.POKEMONB_SPRITES_PATH + "/EmbiteB.png"), EmbiteStart(
           PathConstants.STARTERS_MENU_PATH + "/EmbiteStart.png"),

    // Balls
    Pokeball(PathConstants.SPRITES_MISC_PATH + "/Pokeball.png"), Pokeball4(
             PathConstants.SPRITES_MISC_PATH + "/Pokeball4.gif"),

    // Outlines
    Outline1(PathConstants.MENU_BATTLE_PATH + "/Outline1.png"), Outline2(
             PathConstants.MENU_BATTLE_PATH + "/Outline2.png"), Outline3(
             PathConstants.MENU_BATTLE_PATH + "/Outline3.png"), Outline4(
             PathConstants.MENU_BATTLE_PATH + "/Outline4.png");

例如。

这意味着如果SPRITES_PATH发生更改，您只需更改一处并重新编译。
