Android:如何从Spinner获取所选项目的Id
在本例中,我希望从微调器获取所选项目的Id。在模态类中有两个字段,分别是id和name。我正在列出所有数据,并将此列表设置为适配器。我尝试使用getSelectedItem()方法获取selectedItem Id。但我只能获取项目列表的第一个id 这是我的密码Android:如何从Spinner获取所选项目的Id,android,spinner,android-spinner,Android,Spinner,Android Spinner,在本例中,我希望从微调器获取所选项目的Id。在模态类中有两个字段,分别是id和name。我正在列出所有数据,并将此列表设置为适配器。我尝试使用getSelectedItem()方法获取selectedItem Id。但我只能获取项目列表的第一个id 这是我的密码 public class ModifyEventFragment extends DialogFragment{ Context context; CalEvent eve; Project proj; Spinner eventTyp
