单击长项目后如何在所有 listView 项目上添加复选框？ 安卓Java

Question

I want to add a feature on my project where if the user clicks one of the items on the listView then a checkbox would appear allowing the user to delete 1 or many items at once. Similar to Samsung Notes when you want to delete notes and or folders, etc. However, this concept is completely foreign to me and currently, I don't know where to begin to start this or what topic/resource/sample code I should look for. Also, I have a custom Array Adapter class that I used to order to work with my ListView but it came to my knowledge that you only need 1 array adapter class to make this work which made me confused since I don't know where to begin to manipulate it even further. Any help would be amazing!

Here is my Array Adapter that I have at the moment

//want to create our own custom ArrayAdapter. Going to extends the base class ArrayAdapter and hold our
//Word object
public class WordAdapter extends ArrayAdapter<WordFolder> {
    //constructor - it takes the context and the list of words
    WordAdapter(Context context, ArrayList<WordFolder> word){
        super(context, 0, word);
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent){
        View listItemView = convertView;
        if(listItemView == null){
            listItemView = LayoutInflater.from(getContext()).inflate(R.layout.folder_view, parent, false);
        }

        //Getting the current word
        WordFolder currentWord = getItem(position);
        //making the 3 text view to match our word_folder.xml
        TextView date_created = (TextView) listItemView.findViewById(R.id.date_created);

        TextView title = (TextView) listItemView.findViewById(R.id.title);

        TextView desc = (TextView) listItemView.findViewById(R.id.desc);

        //using the setText to get the text and set it in the textView
        date_created.setText(currentWord.getDateCreated());

        title.setText(currentWord.getTitle());

        desc.setText(currentWord.getTitleDesc());

        return listItemView;

    }

}```  

Answer 1

In R.layout.folder_view add one and make it invisible or gone. OnLongClick make them Visible.
