我确实会选择一个自定义适配器，您可以在其中提供自己的过滤器功能来匹配重音符号和非重音符号。
可以在此处找到执行此操作的示例实现。基本上，您将需要在其中实现实际的过滤performFiltering-我假设您已经有一种方法可以消除查询，因为您当前正在String[]使用消除的版本填充您的查询。您需要将带和不带重音的查询与数组中的条目（您希望使用带和不带重音的条目）进行比较。最后你应该至少有以下四个测试：
accented(query) -> accented(entry)
accented(query) -> deaccented(entry)
deaccented(query) -> accented(entry)
deaccented(query) -> deaccented(entry)
通过动态去重音，您只需要提供String[]带有重音的词，而过滤逻辑（在您的适配器中）将负责匹配（去）重音词。
编辑：正如所讨论的，下面是我正在进行的项目之一的示例实现。
一些指示：
CustomArrayAdapter主要是简化常见任务的包装类；例如与行包装器/视图持有者的交互。基本上它所需要的只是一个构造函数和实现updateRow（显然会从超类的getView方法中调用）。CustomRowWrapper应该很简单。ArrayUtil并ArrayUtil.FilterFuction注意实际的过滤。简单地说，这些充当了 for 循环的替代品，该循环构建了一个新列表，其中包含符合某些条件的所有项目。
public class CARMedicationSuggestionAdapter extends CustomArrayAdapter<CARMedicationInfo, RowWrapper> {
private List<CARMedicationInfo> mMedications;
private Filter mFilter;
/* - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

public CARMedicationSuggestionAdapter(Context context, List<CARMedicationInfo> objects) {
super(RowWrapper.class, context, R.layout.medication_suggestion_item_layout, objects);
// keep copy of all items for lookups
mMedications = new ArrayList<CARMedicationInfo>(objects);

wrapper.getNameTextView().setText(item.toString());

clear();
addAll(filtered);

@Override protected FilterResults performFiltering(final CharSequence constraint) {
// return empty results for 'null' constraint
if (constraint == null) return new FilterResults();
// get all medications that contain the constraint in drug name, trade name or whose string representation start with the constraint

String query = constraint.toString().toLowerCase().trim();
