Android 中的 MediaStore.Video.Media.DISPLAY_NAME 在哪里？

Question

根据 https://developer.android.com/training/data-storage/shared/media?hl=lv on android developers, where the MediaStore.Video.Media.DISPLAY_NAME appears near the begin of this article, I try to find the constant DISPLAY_NAME through a link on the MediaStore.Video.Media class (which is https://developer.android.com/reference/android/provider/MediaStore.Video.Media)，我在这里找不到 DISPLAY_NAME 常量。我在哪里可以找到这个来查看这个常量的含义和描述？

Answer 1

https://cs.android.com/android/platform/superproject/+/master:packages/providers/MediaProvider/apex/framework/java/android/provider/MediaStore.java?q=MediaStore.java&ss=android%2Fplatform%2Fsuperproject&hl=ko

public final class MediaStore {

    public static final class Video {
 
        public interface VideoColumns extends MediaColumns {

        public static final class Media implements VideoColumns {

表示“MediaStore.Video.Media”扩展了MediaColumns。 MediaColumns 有 DISPLAY_NAME

public interface MediaColumns extends BaseColumns {
    public static final String DISPLAY_NAME = "_display_name";
