隐藏搜索结果中的部分标签

Posted 2021-04-01

我有一个列表视图显示区域列表。此列表视图也包含部分。

我想了解如何隐藏搜索结果中的部分标签？或者如何禁用单击部分。

我想只搜索没有部分的搜索后列表中的项目。

searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener(){
        @Override
        public boolean onQueryTextChange(String newText) {
            ArrayList<Item> tempList = new ArrayList<>();

            for(Item temp : countryList){
                if(temp.getTitle().toString().toLowerCase().contains(newText.toLowerCase())) {
                    tempList.add(temp);
                    //Toast.makeText(getApplicationContext(), "hani", Toast.LENGTH_LONG).show();
                }
            }

            CountryAdapter adapter = new CountryAdapter(getApplicationContext(), tempList);
            lvCountry.setAdapter(adapter);
            //adapter.getFilter().filter(newText);
            return true;
        }

        @Override
        public boolean onQueryTextSubmit(String s) {

            return false;
        }
    }); 

答案

好吧，如果您使用搜索视图和ListView与您的项目，您可以始终使用SearchView上面的方法来过滤适配器

searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
                @Override
                public boolean onQueryTextSubmit(String query) {
                    return false;
                }

                @Override
                public boolean onQueryTextChange(String newText) {

                    adapter.getFilter().filter(newText);
                    return false;
                }
            });

您需要在自定义适配器内部

public class SearchAddressAdapter extends BaseAdapter implements Filterable {
private List<AddressItemModel> items;
@Override
public Filter getFilter() {
    if(valueFilter==null) {

        valueFilter=new ValueFilter();
    }

    return valueFilter;
}
private class ValueFilter extends Filter {

    //Invoked in a worker thread to filter the data according to the constraint.
    @Override
    protected FilterResults performFiltering(CharSequence constraint) {
        FilterResults results=new FilterResults();
        if(constraint!=null && constraint.length()>0){
            List<AddressItemModel> filterList=new ArrayList<AddressItemModel>();
            for(int i=0;i<mStringFilterList.size();i++){
                if((mStringFilterList.get(i).getTitle().toUpperCase())
                        .contains(constraint.toString().toUpperCase())) {
                    AddressItemModel contacts = new AddressItemModel();
                    contacts.setTitle(mStringFilterList.get(i).getTitle());
                    filterList.add(contacts);
                }
            }
            results.count=filterList.size();
            results.values=filterList;
        }else{
            results.count=mStringFilterList.size();
            results.values=mStringFilterList;
        }
        return results;
    }


    //Invoked in the UI thread to publish the filtering results in the user interface.
    @SuppressWarnings("unchecked")
    @Override
    protected void publishResults(CharSequence constraint,
                                  FilterResults results) {
        items = (ArrayList<AddressItemModel>) results.values;
        notifyDataSetChanged();
    }
}

这几乎就是:)
