Android open gallery from folder

问题

I want to show a photo in android gallery, and be able to slide throw the others photos on that folder.

Intent intent = new Intent(Intent.ACTION_VIEW);
File f = new File(path);
intent.setDataAndType(Uri.parse("file://" + f.getAbsolutePath()), "image/*");
mContext.startActivity(intent);

thats how i am doing it now, but wont let me slide throw the rest of the images in the folder. i tried:

This question is from five years ago, However I want to give an answer that worked for me instead of the correct answer.

In order to show the photo and slide through the others photos, we need to give to the intent not the file uri but the media uri.

public void ShowPhoto(File imageFile) {

    String mediaId = "";

    String[] projection = new String[] {
            MediaStore.Images.Media._ID,
            MediaStore.Images.Media.DISPLAY_NAME
    };

    Cursor cursor = getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
            projection, null, null, null);

    while (cursor != null && cursor.moveToNext()) {
        String name = cursor.getString((cursor.getColumnIndex(MediaStore.Images.ImageColumns.DISPLAY_NAME)));
        if(name.equals(imageFile.getName())){
            mediaId = cursor.getString((cursor.getColumnIndex(MediaStore.Images.ImageColumns._ID)));
            break;
        }
    }

    Uri mediaUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;

    if(!mediaId.equals("")){
        mediaUri = mediaUri.buildUpon()
                .authority("media")
                .appendPath(mediaId)
                .build();
    }

    Log.d("TagInfo","Uri:  "+mediaUri);

    Intent intent = new Intent(Intent.ACTION_VIEW, mediaUri);
    startActivity(intent);

}
