Как получить абсолютный путь выбранного видео из списка в onContextItemSelected от android?

Question

Я новичок в Android. Я создал одно представление списка, в котором перечислены все видеофайлы из определенной папки. Я также создал контекстное меню, в котором есть опция для удаления видео. Но я не знаю, как получить абсолютный URL выбранного видео на onContextItemSelected.

Вот мой GetView() из CustomArrayAdapter

public View getView(int position, View convertView, ViewGroup parent){ 
    ViewHolder holder; 
    VideoListRowItem videoListRowItem = getItem(position); 

    LayoutInflater mInfalter = (LayoutInflater) context 
      .getSystemService(Activity.LAYOUT_INFLATER_SERVICE); 

    if(convertView == null){ 
     convertView = mInfalter.inflate(R.layout.list_row_video, null); 
     holder = new ViewHolder(); 
     holder.textView = (TextView) convertView.findViewById(R.id.name_video); 
     holder.videoView = (ImageView) convertView.findViewById(R.id.video_icon); 
     holder.videoPath = (TextView) convertView.findViewById(R.id.video_path); 


    }else{ 
     holder = (ViewHolder) convertView.getTag(); 
    } 


    holder.textView.setText(videoListRowItem.getTitle()); 
    holder.videoView.setImageBitmap(videoListRowItem.getVideoId()); 
    holder.videoPath.setText(videoListRowItem.getVideoPath()); 

    return convertView; 
} 

Здесь onContextItemSelected()

@Override 
public boolean onContextItemSelected(MenuItem item) { 
    AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo) item.getMenuInfo(); 
    // Here I want to get absolute url of selected video 
    String path = '' 
    switch (item.getItemId()) { 
     case R.id.analyze: 
      Toast.makeText(getActivity(), path, Toast.LENGTH_SHORT).show(); 
      //editNote(info.id); 
      return true; 
     case R.id.delete_video: 
      Toast.makeText(getActivity(), path, Toast.LENGTH_SHORT).show(); 
      //deleteNote(info.id); 
      return true; 
     default: 
      return super.onContextItemSelected(item); 
    } 
}

Answer 1

Вот код

 case R.id.delete_video: 
      #info.position returns the index of the item in the listview 
      VideoListRowItem videoListRowItem =(VideoListRowItem)videoListRowItem.get(info.position); 

// используйте класс videoListRowItem, чтобы получить видеоролик
