在这个项目中，我无法在控制台输出中获取是否选择了Checkbox数据。

    @Override
    public String toString() {
      return firstName.get() + " " + lastName.get() + (injured.get()?" (injured)":"");
    }
  }
}

它给我的输出像

Selected row: Gareth    Bale

但是它并不能告诉天气复选框是否处于选中状态：

public void onChanged

我需要这样的输出：

 Selected row: Gareth    Bale   true

要么

 Selected row: Gareth    Bale   false
