与枚举在安卓工作 [英] Working with Enums in android

问题描述

我快与计算活动我正与Android中为我的应用程序进行。我尝试创建一个性别枚举，但出于某种原因，获得的语法错误，将EnumBody完成EnumDeclaration。

I am almost done with an calculation activity I am working with in android for my app. I am try to create a Gender Enum, but For some reason getting Syntax error, insert "EnumBody" to complete EnumDeclaration.

public static enum Gender
{
    static
    {
        Female = new Gender("Female", 1);
        Gender[] arrayOfGender = new Gender[2];
        arrayOfGender[0] = Male;
        arrayOfGender[1] = Female;
        ENUM$VALUES = arrayOfGender;
    }
}

我也试了一下没有静态{}但我得到了相同的语法错误。我一直在Google上搜寻一整天阅读所有关于枚举，我在编程绝对新手我刚开始上大学的软件工程，如果这是一个愚蠢的问题，时间我道歉提前。

I have also tried it without the static {} but I get the same syntax error. I have been googling all day reading all about enums, I am an absolute beginner in programming I just start started college for software engineering if this is a stupid question, I apologize ahead of time.

推荐答案

到底从哪里找到这样的语法？ Java的枚举很简单，你只需指定的值。

Where on earth did you find this syntax? Java Enums are very simple, you just specify the values.

public enum Gender {
   MALE,
   FEMALE
}

如果你想他们是更复杂的，你可以像这样添加值给他们。

If you want them to be more complex, you can add values to them like this.

public enum Gender {
    MALE("Male", 0),
    FEMALE("Female", 1);

    private String stringValue;
    private int intValue;
    private Gender(String toString, int value) {
        stringValue = toString;
        intValue = value;
    }

    @Override
    public String toString() {
        return stringValue;
    }
}

然后用枚举，你会做这样的事情：

Then to use the enum, you would do something like this:

Gender me = Gender.MALE
