在android中使用领域的通用搜索

Question

创建领域的通用搜索。我有RecyclerView可以包含不同字符串值作为来自不同类的字段。

我使用SearchView和SearchManager实现了搜索功能 我面临的问题是代码的重复。 Recyclerview具有来自不同类的字符串值，即CallReasonInfo，ObsercationInfo等。

现在我不得不创建不同的搜索查询来搜索所有这些类中的记录。

我正在寻找一种方法，我不需要为每种特定类型的RealmResults创建/添加监听器

lookupSearchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
            @Override
            public boolean onQueryTextSubmit(String query) {


                RealmResults<CallReasonInfo> searchCallReasonInfo =
                                getCallReasonInfoQuery()
                                .contains("callReasonName",query)
                                .findAll();

                searchCallReasonInfo.addChangeListener(new RealmChangeListener<RealmResults<CallReasonInfo>>() {
                    @Override
                    public void onChange(RealmResults<CallReasonInfo> elements) {

                        adapter.setSearchListAdapter(elements);

                    }
                });
                return true;
            }

            @Override
            public boolean onQueryTextChange(String newText) {

                Log.e(TAG , "onQueryTextChange "+newText);
                RealmResults<CallReasonInfo> searchCallReasonInfo =
                                getCallReasonInfoQuery()
                                .contains("callReasonName",newText.trim(), Case.INSENSITIVE)
                                .findAllAsync();

                searchCallReasonInfo.addChangeListener(new RealmChangeListener<RealmResults<CallReasonInfo>>() {
                    @Override
                    public void onChange(RealmResults<CallReasonInfo> elements) {


                        adapter.setSearchListAdapter(elements);

                    }
                });
                return true;
            }
        });

适配器中的

我有以下功能

 public void setSearchListAdapter(RealmResults<E> results){

        lookupInfo = results;
        notifyDataSetChanged();
    }

基于下面写的ListAdapter代码，我必须使用查询而不是可过滤的

public class SearchListAdapter <E extends RealmModel>  extends RecyclerView.Adapter<SearchListAdapter.SearchListViewHolder>
                                                        implements  View.OnClickListener {


    private static final String TAG = "SearchListAdapter";
    private RealmResults<E> lookupInfo;
    private static String lookupType;
    private static ItemClickListener itemClickListener;
    public  SearchListAdapter( RealmResults<E>  resultInfo, String lookupType, ItemClickListener listener) {

        this.lookupType = lookupType;
        lookupInfo = resultInfo;
        itemClickListener = listener;
   }

    @Override
    public SearchListViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {

        View v = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.seach_list_item, parent, false);

        SearchListAdapter.SearchListViewHolder viewHolder = new SearchListAdapter.SearchListViewHolder(v);
        return viewHolder;

    }

    @Override
    public void onBindViewHolder(SearchListViewHolder holder, int position) {
        holder.bind(lookupInfo.get(position));
    }

    @Override
    public int getItemCount() {
        return lookupInfo==null ? 0 : lookupInfo.size();
    }

    @Override
    public void onClick(View v) {


        Log.e(TAG , "Clicked "+v.getTag());


    }



    public static class SearchListViewHolder extends RecyclerView.ViewHolder {

        private TextView tvItemName;

        public SearchListViewHolder(View itemView) {
            super(itemView);

            tvItemName = (TextView) itemView.findViewById(R.id.tvItemName);


        }

        public void bind(final RealmModel item){





        }
    }


    public void setSearchListAdapter(RealmResults<E> results){

        lookupInfo = results;
        notifyDataSetChanged();
    }



}
