如何使此适配器可搜索？

如何解决如何使此适配器可搜索？

这是我的列表视图的适配器.. 我想向其中添加过滤器或搜索功能。请帮我。 但我看过很多代码，但没有一个能帮助我实现它。而且我还没有看到扩展 ArrayAdapter 的适配器，其中有一个 getFilter。所以请帮助我。

public class FullNameAdapter extends ArrayAdapter<Name> implements Filterable {

    public FullNameAdapter(Context context,ArrayList<Name> words){
        super(context,words);
    }

    @NonNull
    @Override
    public View getView(int position,@Nullable View convertView,@NonNull ViewGroup parent) {

        View listItemView = convertView;
        if(listItemView == null) {
            listItemView = LayoutInflater.from(getContext()).inflate(R.layout.main_listview,parent,false);
        }
        Name currentWord = getItem(position);

        TextView mainNumber = (TextView) listItemView.findViewById(R.id.mainNumber_page);
        mainNumber.setText(currentWord.getMainNumber());

        TextView sanskritName = (TextView) listItemView.findViewById(R.id.sanskrit_name_text_view_ml);
        sanskritName.setText(currentWord.getSanskritName());

        TextView scientificName = (TextView) listItemView.findViewById(R.id.scientific_name_text_view_ml);
        scientificName.setText(currentWord.getScientificName());

        TextView familyName = (TextView) listItemView.findViewById(R.id.family_text_view_ml);
        familyName.setText(currentWord.getFamilyName());

        ShapeableImageView panel_IMG_back = (ShapeableImageView) listItemView.findViewById(R.id.mainList_imageView);
        Glide.with(getContext()).load(currentWord.getPicId()).into(panel_IMG_back);
        panel_IMG_back.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                Dialog builder = new Dialog(getContext());
                builder.requestWindowFeature(Window.FEATURE_NO_TITLE);
                builder.getWindow().setBackgroundDrawable(
                        new ColorDrawable(android.graphics.Color.TRANSPARENT));

                builder.setOnDismissListener(new DialogInterface.OnDismissListener() {
                    @Override
                    public void onDismiss(DialogInterface dialogInterface) {
                        //nothing;
                    }
                });

                ZoomageView imageView = new ZoomageView(getContext());
                imageView.setImageResource(currentWord.getPicId());
                builder.addContentView(imageView,new RelativeLayout.LayoutParams(
                        ViewGroup.LayoutParams.MATCH_PARENT,ViewGroup.LayoutParams.MATCH_PARENT));

                builder.setCanceledOnTouchOutside(true);
                builder.show();

            }
        });return listItemView;}}

请帮忙！

在MAIN ACTIVITY，Main activity中的Action Bar SEARCH VIEW，应该怎么做？这里

 @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.list_menu,menu);
        MenuItem menuItem = menu.findItem(R.id.action_search);
        SearchView searchView = (SearchView) menuItem.getActionView();
        searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
            @Override
            public boolean onQueryTextSubmit(String query) {
                return false;
            }
            @Override
            public boolean onQueryTextChange(String newText) {
                
                return true;
            }
        });
        return super.onCreateOptionsMenu(menu);
    }

这些是我添加到数组列表中的对象，我想在其中的一些对象中进行搜索，如果数组中的字符串匹配，则数组列表可以显示在列表中。但如果 Name 没有匹配的字符串，它应该去！

private void smallaaray() {
        array = new ArrayList<Name>();
        array.add(new Name("1","akhil","",R.drawable.0,R.string.0,R.drawable.0));

请帮忙！

解决方法

适配器只关心数据和视图。过滤和搜索应该是对数据源的操作。因此，您应该在对数据源进行操作后更新适配器

,

您可以创建一个自定义过滤器，如下所示， 将您的列表传递给适配器的 setFilterList() 方法以进行搜索/过滤

触发搜索：

adapter.getFilter().filter();

public class FullNameAdapter extends ArrayAdapter<Name> implements Filterable {

    public FullNameAdapter(Context context,ArrayList<Name> words) {
        super(context,words);
    }

    @NonNull
    @Override
    public View getView(int position,@Nullable View convertView,@NonNull ViewGroup parent) {

        View listItemView = convertView;
        if (listItemView == null) {
            listItemView = LayoutInflater.from(getContext()).inflate(R.layout.item_bonus,parent,false);
        }
        Name currentWord = getItem(position);

        return listItemView;
    }

    CustomFilter filter;

    public void setFilterList(List<Name> filterList) {
        this.filterList = filterList;
    }

    List<Name> filterList;

    @NonNull
    @Override
    public CustomFilter getFilter() {
        return filter;
    }

    public class CustomFilter extends Filter {
        ArrayList<Name> filterList;

        public CustomFilter(ArrayList<Name> filterList) {
            this.filterList = filterList;
        }

        //FILTERING OCCURS
        @Override
        protected FilterResults performFiltering(CharSequence constraint) {
            FilterResults results = new FilterResults();
            //CHECK CONSTRAINT VALIDITY
            if (constraint != null && constraint.length() > 0) {
                //CHANGE TO UPPER
                constraint = constraint.toString().toUpperCase();
                //STORE OUR FILTERED PLAYERS
                ArrayList<Name> filteredPlayers = new ArrayList<>();
                if (filterList != null) {
                    for (int i = 0; i < filterList.size(); i++) {
                        //CHECK
                        try {
                            if (filterList.get(i).getNameName().toUpperCase().contains(constraint)) {
                                //ADD PLAYER TO FILTERED PLAYERS
                                filteredPlayers.add(filterList.get(i));
                            }
                        } catch (Throwable e) {
                            e.printStackTrace();
                        }
                    }
                }
                results.count = filteredPlayers.size();
                results.values = filteredPlayers;
            } else {
                results.count = filterList.size();
                results.values = filterList;
            }
            return results;
        }

        @Override
        protected void publishResults(CharSequence constraint,FilterResults results) {
            clear();
            if (results != null && results.count > 0) {
                add((Name) results.values);
                notifyDataSetChanged();
            }
        }
    }
}
