Delete or hide a row in a list view

Question

Hello everyone I have a problem in regards with the deletion or hiding of list in a list view something like .hide() in javascript . I know there are lots of answers here about it but it seems It didn't answer my problem. To explain clearly, below is some part of my code.

    package sample.wew.wew;

    import info.androidhive.sqlite.model.Message;

    import java.util.ArrayList;
    import java.util.List;

    import android.content.Intent;
    import android.database.Cursor;
    import android.os.Bundle;
    import android.support.v4.app.Fragment;
    import android.util.Log;
    import android.view.LayoutInflater;
    import android.view.View;
    import android.view.ViewGroup;
    import android.widget.AdapterView;
    import android.widget.ArrayAdapter;
    import android.widget.ListAdapter;
    import android.widget.ListView;
    import android.widget.SimpleCursorAdapter;
    import android.widget.TextView;
    import android.widget.Toast;
    import android.widget.AdapterView.OnItemClickListener;

    public class QuestionsSent extends Fragment {

        private static final String TAG = "Question";

        private static List questions;
        protected ListAdapter adapter;
        ListView theList;   

        @SuppressWarnings("deprecation")
        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

            View view;

            view = inflater.inflate(R.layout.questions_main_layout, container, false);
            AskdDatabaseHelper msg_db = new AskdDatabaseHelper(getActivity());

            Cursor cursor = msg_db.FetchQuestion("S");

            String[] fromFieldNames = new String[] { "msg_from_user", "msg_message" };
            int[] toViewIDs = new int[] { R.id.tvMessage, R.id.tvMessageSender };

            adapter = new QuestionsCursorAdapter(getActivity(), // Context
                            R.layout.question_detail, // Row layout template
                            cursor, // cursor (set of DB records to map)
                            fromFieldNames, // DB Column names
                            toViewIDs // View IDs to put information in
            );

            theList = (ListView) view.findViewById(R.id.list);
            theList.setAdapter(adapter);
            theList.setOnItemClickListener(new AdapterView.OnItemClickListener() {

                @Override
                public void onItemClick(AdapterView<?> parent, View view,
                                int position, long id) {
                    /*
                    Log.v(TAG, ": NAAY GI CLICK");
                    Intent intent = new Intent(getActivity(), Sent_details.class);
                    Cursor cursor = (Cursor) adapter.getItem(position);
                    Log.d("TAG", "" + adapter.getItem(position));
                    intent.putExtra("MESSAGE_ID", cursor.getString(cursor.getColumnIndex("msg_message")));
                    startActivity(intent);
                    */

                    // HERE IS WHERE I WANT TO PUT MY CODE TO DELETE OR HIDE A LIST
                }
            });      

            if(adapter.isEmpty()){
                view = inflater.inflate(R.layout.fragments_question_new, container, false);
                ((TextView)view.findViewById(R.id.textView)).setText("No Sent Questions");
            }

            return view;

        }

}

Here you can do something like this it will ask you in the form of dialogue box to weather delete the record or not and after clicking yes it will delete the record. Hope this helps you ...

userList.setOnItemLongClickListener(new OnItemLongClickListener() 
    {
        public boolean onItemLongClick(AdapterView<?> arg0, View arg1,final int arg2, long arg3)
        {

        build = new AlertDialog.Builder(HomePage.this);
        build.setTitle("Delete " + FirstName.get(arg2));
        build.setMessage("Do you want to delete ?");
        build.setPositiveButton("Yes", new DialogInterface.OnClickListener() 
        {
            public void onClick(DialogInterface dialog, int which)
            {
            Toast.makeText(getApplicationContext(), FirstName.get(arg2) + " " + LastName.get(arg2) + " is deleted.", 3000).show();
                dataBase = mHelper.getWritableDatabase();
                dataBase.delete(DatabaseActivity.TABLE_NAME, DatabaseActivity.KEY_ID + "=" + userId.get(arg2), null);

                dataBase.close();
                displayData();
                dialog.cancel();
            }
                    });

            build.setNegativeButton("No", new DialogInterface.OnClickListener() 
            {
                public void onClick(DialogInterface dialog, int which) 
                {
                    dialog.cancel();
                    }
                });
            AlertDialog alert = build.create();
            alert.show();
            return true;
        }
    });
}
