Java 如何基于微调器项目选择在recyclerview中应用过滤器？
您好，我遇到了一种情况，需要根据Java 如何基于微调器项目选择在recyclerview中应用过滤器？,java,android,filter,android-recyclerview,spinner,Java,Android,Filter,Android Recyclerview,Spinner,您好，我遇到了一种情况，需要根据spinner选择在活动中加载图像。在这里，我将从api中获取这些图像作为ArrayList和微调器值。我不知道如何根据微调器选择应用过滤器。请想出一个解决办法。下面是我的代码 对于活动： public class MedicalRecordsActivity extends BaseActivity implements MedicalRecordsView { @Inject MedicalRecordsPresenter mPresenter; @Bin
