How to filter markers on Android Map from Sqlite

Hi I am newbie to programming and would like some assistance please.

I want to create a filter to show specific markers as per user selection (CheckBoxes).

The Filter must have Public Markers and Private Markers option (The database has a column 'RadioButton' which will either have values "public" or "Private") .

I have managed to add/show all marker stored in SQLite database to my Map but I need to arrange them in groups and allow user to select (Checkbox) which ever one they need to display.

here is my Code to add all markers:

    public void onMapReady(GoogleMap googleMap) {

    mGoogleMap = googleMap;

    Database_Helper dbHelper = new Database_Helper(Maps.this);
       try {
          dbHelper.getDatabaseName();
        } catch (Exception e) {
        Toast.makeText(Maps.this, "Database Does not Exists",       Toast.LENGTH_SHORT).show();
        }
      final SQLiteDatabase db = dbHelper.getReadableDatabase();

      Cursor cursor = db.rawQuery("SELECT * FROM " + TABLE_NAME, null);
            LatLngBounds.Builder mapBuilder = new LatLngBounds.Builder();
      boolean addedMarker = false;

      if (cursor != null) {
          while (cursor.moveToNext()) {

            int lat = cursor.getColumnIndexOrThrow(COL3);
            int lng = cursor.getColumnIndexOrThrow(COL4);
            int title = cursor.getColumnIndexOrThrow(COL5);
            int radiob = cursor.getColumnIndexOrThrow(COL13);

            String title = cursor.getString(title);
            double latitude = cursor.getDouble(lat);
            double longitude = cursor.getDouble(lng);
            String radio = cursor.getString(radiob);

            LatLng location = new LatLng(latitude, longitude);
            MarkerOptions options = new MarkerOptions()
                    .title(event)
                    .snippet(date)
                    .position(location)
                    .anchor(0.5F, 1.0F)
                    .icon(BitmapDescriptorFactory.defaultMarker        

           (BitmapDescriptorFactory.HUE_AZURE))
                    .draggable(false);

            final Marker marker = mGoogleMap.addMarker(options);
            mapBuilder.include(marker.getPosition());

            addedMarker = true;`

My Xml Layout : With Checkboxes

    <CheckBox
