Android：SetDropDownViewResource与AutoCompleteTextView不兼容？

Question

DropDownViewResource应用于微调器，而不应用于AutoCompleteTextView。

此作品：

ArrayAdapter<String> arrayAdapter = new ArrayAdapter<>(this.getActivity(), R.layout.spinner_item, usersHistory);
arrayAdapter.setDropDownViewResource(R.layout.spinner_dropdown_item);

Spinner userSpinner = dialogLayout.findViewById(R.id.country);
userSpinner.setAdapter(ArrayAdapter);

这不起作用：

ArrayAdapter<String> arrayAdapter = new ArrayAdapter<>(this.getActivity(), R.layout.spinner_item, usersHistory);
arrayAdapter.setDropDownViewResource(R.layout.spinner_dropdown_item);

AutoCompleteTextView userAutoCompleteTextView = dialogLayout.findViewById(R.id.country);
userAutoCompleteTextView.setAdapter(ArrayAdapter);

有人知道如何为AutoCompleteTextView设置“自定义下拉菜单”吗？
