patientListAdapter=新的patientListAdapter(requireContext((，getRegisterPatientList，this(；recycler_view.setAdapter(patientListAdapter(//这个错误

java：弹出窗口：

public class DateTimeCoordinator extends Fragment implements PatientListCoordinatorAdapter.SelectItemClickListner {
patient_details.setOnClickListener(new View.OnClickListener() {

您的Activity或Fragment(包含RecyclerView和适配器(没有实现PatientListAdapter.SelectIemClickListner，而是有一个View.OnClickListener实现。你应该在昏迷后添加SelectIemClickListner，实现所需的方法(mySelectIemListner(int i)(，然后尝试构建一个应用

它应该如何查找和Activity的一些示例

class CustomActivity : AppCompatActivity(),
View.OnClickListener, PatientListAdapter.SelectIemClickListner {
override fun mySelectIemListner(i: Integer) {
// on item click implementation
}
// rest of code
