java - Android，Java)以@StringDef检索 bundle 数据？

如何检查从上一个活动传递的捆绑包是否为@StringDef之一？

@Retention(RetentionPolicy.SOURCE)
@StringDef({Region.RegionA, Region.RegionB, Region.RegionC})
public @interface Region {
    String RegionA = "a";
    String RegionB = "b";
    String RegionC = "c";
}


private @Region String mRegion;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

    ...
    mRegion = getArguments().getString("region"); // Check if this is @Region?
    ...

}

最佳答案

添加。
//noinspection ResourceTypemRegion = getArguments().getString("region");
