ListView not populating using Cursoradapter

Question

I have an input page which submits 4 strings into the helper. The helper is supposed to get the data and put it into the listView.

When I insert my data, the app doesnt crash but it leads me to the listview page with no rows inflated. The 4 data inputs are all strings and is submitted through a button. I'm not too sure what is wrong with my code. Would appreciate some advice :)

listview code

public class MyActivitiesPage extends AppCompatActivity {
    private Cursor model = null;
    private ListView list;
    private dbHandler helper = null;
    private activityAdapter adapter = null;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.my_activities_page);

        helper = new dbHandler(this);
        list = findViewById(R.id.listView);
        model = helper.getall();
        adapter = new activityAdapter(this, model, 0);
        list.setAdapter(adapter);
    }
    
    public static class activityHolder {
        private TextView activitytext;
        private TextView datetext;
        private TextView timetext;
        private TextView addresstext;

        activityHolder(View row) {
            activitytext = row.findViewById(R.id.activitytext);
            datetext = row.findViewById(R.id.datetext);
            timetext = row.findViewById(R.id.timetext);
            addresstext = row.findViewById(R.id.addresstext);
        }

        void populateFrom(Cursor c, dbHandler helper){
            activitytext.setText(helper.getActi(c));
            datetext.setText(helper.getDate(c));
            timetext.setText(helper.getTime(c));
            addresstext.setText(helper.getAddr(c));
        }
    }

    class activityAdapter extends CursorAdapter {
        activityAdapter(Context context, Cursor cursor, int flags) {
            super(context, cursor, flags);
        }

        public void bindView(View view, Context context, Cursor cursor) {
            activityHolder holder = (activityHolder) view.getTag();
            holder.populateFrom(cursor, helper);
        }
        public View newView(Context context, Cursor cursor, ViewGroup parent) {
            LayoutInflater inflater = getLayoutInflater();
            View row = inflater.inflate(R.layout.row, parent, false);
            activityHolder holder = new activityHolder(row);
            row.setTag(holder);
            return (row);
        }
    }

    public Cursor getall() {

    }
