Android 将 String 解析为 StringDef

Question

我在我的代码中声明了一个 @StringDef :

@StringDef({NotificationAction.DISPLAYED, NotificationAction.CONTENT_CLICKED,
    NotificationAction.ACTION_CLICKED, NotificationAction.DISMISSED})
@Retention(RetentionPolicy.SOURCE)
public @interface NotificationAction {
    String DISPLAYED = "Displayed";
    String CONTENT_CLICKED = "ContentClicked";
    String ACTION_CLICKED = "ActionClicked";
    String DISMISSED = "Dismissed";
}

如何将新字符串解析为 NotificationAction 而无需单独与每个字符串进行比较？

在枚举中，我可以直接使用valueOf函数。我在这里找不到类似的东西。

看来除了实施它你真的无能为力。我所做的是以下内容。

public class Job {

    @IntDef(value = {
            Status.STOPPED,
            Status.STARTED,
            Status.NEW
    })
    @Retention(RetentionPolicy.SOURCE)
    @interface JobStatus {
    }

    public static class Status {
        public static final int STOPPED = 0;
        public static final int STARTED = 1;
        public static final int NEW = 2;

        @JobStatus
        static int getStatus(int status) {
            return status;
        }

        @JobStatus
        static int fromName(String name) {
            switch (name) {
                case "STOPPED":
                    return STOPPED;
                case "STARTED":
                    return STARTED;
                case "NEW":
                    return NEW;
                default:
                    return NEW;
            }
        }
    }
}

也许能帮到你。
