推荐答案

画廊显示mediastore数据。从您必须删除mediastore数据库行视频画廊彻底删除该文件。

Gallery is displaying mediastore data. To completely delete the file from the gallery you have to delete the mediastore database row for the video.

• 在code从mediastore删除的记录。

• In code remove the record from the mediastore.

// delete the mediastore entry;
getContext().getContentResolver().delete(mediaStoreUri, null, null);

现在所有你需要的是mediaStoreUri可以从文件路径得到它。

Now all you need is the mediaStoreUri you can get it from the file path.

问题与上面的链接PFER他们使用的ContentUris.withAppendedId静态方法来得到URI，而是他们只是添加斜线和字符串我想$ P $它

Problem with above link I would prefer they use the ContentUris.withAppendedId static method to get the Uri but instead they just add a slash and string it out

Uri mediaStoreUri = ContentUris.withAppendedId(
    MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
                            ImageId);
