CursorAdapter con aggiunta di una riga extra alla fine.

Ora dobbiamo riscrivere il codice per un CursorAdapter, aggiungendo elementi alla fine.
Eccolo:

public class MainActivity extends AppCompatActivity {

    Helper helper;
    ListView listView;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        listView=(ListView)findViewById(R.id.listView);
        /*helper=new Helper(this);
        helper.save("Brontolo");
        helper.save("Cucciolo");
        helper.save("Pisolo");
        helper.save("Gongolo");
        helper.save("Mammolo");
        helper.save("Dotto");
        helper.save("Eolo");*/


        MyCursorAdapter adapter=new MyCursorAdapter(this,helper.query());

        listView.setAdapter(adapter);
        LayoutInflater inflater=(LayoutInflater)getSystemService(LAYOUT_INFLATER_SERVICE);
        View v=inflater.inflate(R.layout.row,null);
        EditText editText=(EditText) v.findViewById(R.id.editText);
        editText.setText("EXTRA");
        listView.addFooterView(v);


    }

    class MyCursorAdapter extends CursorAdapter{

        public MyCursorAdapter(Context context, Cursor c) {
            super(context, c);
        }

        @Override
        public View newView(Context context, Cursor cursor, ViewGroup viewGroup) {
            LayoutInflater inflater=(LayoutInflater)getSystemService(LAYOUT_INFLATER_SERVICE);
            return inflater.inflate(R.layout.row,null);
        }

        @Override
        public void bindView(View view, Context context, Cursor cursor) {
            EditText editText=(EditText) view.findViewById(R.id.editText);
            editText.setText(cursor.getString(cursor.getColumnIndex("nome")));
        }
    }
}
