Answer 1

대신 VideoView의, ImageView를 사용하여 영상의 미리보기를 얻을.

@Override 
public View getView(int position, View convertView, ViewGroup parent) { 
    ... 
    Bitmap thumbnail = ThumbnailUtils.createVideoThumbnail(values[position], 
      MediaStore.Video.Thumbnails.MICRO_KIND); 
    imageView.setImageBitmap(thumbnail); 
    ... 
}
