是否有将美国州名称转换为州代码的实用程序.例如.亚利桑那州飞往亚利桑那州

Question

我需要将完整的州名转换为其官方州地址代码。 例如，从纽约弦乐中，我需要制作纽约。 现在我可以把这一切都放在一个哈希图中，但似乎必须有一个实用程序？我在一个安卓环境中。 但是，我不想仅为这个实用程序导入一个大型库。谢谢

Answer 1

我有现成的 - 你可以使用它：

Map<String, String> states = new HashMap<String, String>();
states.put("Alabama","AL");
states.put("Alaska","AK");
states.put("Alberta","AB");
states.put("American Samoa","AS");
states.put("Arizona","AZ");
states.put("Arkansas","AR");
states.put("Armed Forces (AE)","AE");
states.put("Armed Forces Americas","AA");
states.put("Armed Forces Pacific","AP");
states.put("British Columbia","BC");
states.put("California","CA");
states.put("Colorado","CO");
states.put("Connecticut","CT");
states.put("Delaware","DE");
states.put("District Of Columbia","DC");
states.put("Florida","FL");
states.put("Georgia","GA");
states.put("Guam","GU");

Answer 2

我知道

这并不能回答这个问题，但以防万一有人需要相反的情况：使用州/省缩写作为键，使用名称作为值。我花了几分钟来重新格式化地图。此外，接受答案中魁北克的缩写是错误的。

Answer 5

我认为最简单的方法是使用HashMap。即使有一个库来转换它，它也可能会使用相同的东西。

Map<String, String> states = new HashMap<String, String>();
states.put("Arizona", "AZ");
states.put("California", "CA");
// So on and so forth...
// Then you could create a method like
public String toStateCode(String s) {
    return states.get(s);
}

    WY("WY", "Wyoming");
    private final String key;
    private final String value;
    State(String key, String value) {
        this.key = key;
        this.value = value;

使用代码和值构建一个Map<String, String>，这很简单，而且数据很少。这没有"实用程序"，它非常特定于您正在构建的应用程序。

Answer 8

我不这么认为（至少我从未听说过）。但是您始终可以使用字典来完成此操作。

Answer 9

这是 Kotlin 代码：

enum class State(val stateName: String) {
    AK("Alaska"),
    AL("Alabama"),
    AR("Arkansas"),
    AZ("Arizona"),
    CA("California"),
    CO("Colorado"),
    CT("Connecticut"),
    DE("Delaware"),
    FL("Florida"),
    GA("Georgia"),
    HI("Hawaii"),
    IA("Iowa"),
    ID("Idaho"),
    IL("Illinois"),
    IN("Indiana"),
    KS("Kansas"),
    KY("Kentucky"),
    LA("Louisiana"),
    MA("Massachusetts"),
    MD("Maryland"),
    ME("Maine"),
    MI("Michigan"),
    MN("Minnesota"),
    MO("Missouri"),
    MS("Mississippi"),
    MT("Montana"),
    NC("NorthCarolina"),
    ND("NorthDakota"),
    NE("Nebraska"),
    NH("NewHampshire"),
    NJ("NewJersey"),
    NM("NewMexico"),
    NV("Nevada"),
    NY("NewYork"),
    OH("Ohio"),
    OK("Oklahoma"),
    OR("Oregon"),
    PA("Pennsylvania"),
    RI("RhodeIsland"),
    SC("SouthCarolina"),
    SD("SouthDakota"),
    TN("Tennessee"),
    TX("Texas"),
    UT("Utah"),
    VA("Virginia"),
    VT("Vermont"),
    WA("Washington"),
    WI("Wisconsin"),
    WV("WestVirginia"),
    WY("Wyoming")
}

将其用作：

val alaska = State.valueOf("AK").stateName
val virginia = State.VA.stateName
