Question

我有以下片段，它显示一个自定义的listiview，其中每行有2个项目。日语作品，意思是葡萄牙语。我正在尝试实施一个searh吧。栏显示，但我不知道如何搜索和过滤列表

真实的清单，如果比这长得多。我知道我应该在xml中实现列表，但这更容易。

public class Dicionario extends ListFragment {



    //ArrayList holds the data (as HashMaps) to load into the ListView
    ArrayList<HashMap<String,String>> list = new ArrayList<HashMap<String,String>>();
    //SimpleAdapter does the work to load the data in to the ListView
    private SimpleAdapter sa;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.fragment_dicionario, container,
                false);


        ((MainActivity) getActivity()).setActionBarTitle(getString(R.string.dicionariotitle));


        Arrays.sort(termos, new ColumnComparator(0));


        HashMap<String,String> item;

        for(int i = 0; i< termos.length; i++){
            item = new HashMap<String,String>();
            item.put( "line1", termos[i][0]);
            item.put( "line2", termos[i][1]);
            list.add( item );
        }

        sa = new SimpleAdapter(getActivity().getApplicationContext(), list, R.layout.my_two_lines, new String[] { "line1","line2" }, new int[] {R.id.line_a, R.id.line_b});
        setListAdapter(sa);
        return rootView;
        //setListShown(true);




    }



    private String[][] termos =
            {{"DOJÔ","Área de Treinamento"},
                    {"JÔ-SEKI","Lugar onde se sentam as autoridades"},
                    {"REI-HÔ","Saudação"},
                    {"REI","Cumprimento"},
                    {"MOKUSO","Meditação (Fechar os olhos e manter  silêncio)"},
                    {"ZA-REI","Cumprimento ajoelhado"},
                    {"RITSU-REI","Cumprimento em pé"},
                    {"SHI-HAN","Mestre"},
                    {"SENSEI","Professor"},
                    {"SEITÔ","Aluno"},
                    {"DÔO-HAI","Colegas"},
                    {"NINTAI","Perserverança"},
                    {"DORYOKU","Esforço, empenho"},
                    {"HISSHYÔ","Ei de vencer"},
                    {"KATANÁ","Espada"},
                    {"DAITÔO","Espada Maior"},
                    {"SHÔOTÔO","Espada Menor"},
                    {"TANTÔO","Punhal"},
                    {"BOKKEN","Espada de Madeira"}

            };

@Override
public void onDestroyView() {
    super.onDestroyView();
    ButterKnife.reset(this);
}

//ArrayList holds the data (as HashMaps) to load into the ListView ArrayList<HashMap<String,String>> list = new ArrayList<HashMap<String,String>>(); //SimpleAdapter does the work to load the data in to the ListView private SimpleAdapter sa; @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View rootView = inflater.inflate(R.layout.fragment_dicionario, container, false); ((MainActivity) getActivity()).setActionBarTitle(getString(R.string.dicionariotitle)); Arrays.sort(termos, new ColumnComparator(0)); HashMap<String,String> item; for(int i = 0; i< termos.length; i++){ item = new HashMap<String,String>(); item.put( "line1", termos[i][0]); item.put( "line2", termos[i][1]); list.add( item ); } sa = new SimpleAdapter(getActivity().getApplicationContext(), list, R.layout.my_two_lines, new String[] { "line1","line2" }, new int[] {R.id.line_a, R.id.line_b}); setListAdapter(sa); return rootView; //setListShown(true); } private String[][] termos = {{"DOJÔ","Área de Treinamento"}, {"JÔ-SEKI","Lugar onde se sentam as autoridades"}, {"REI-HÔ","Saudação"}, {"REI","Cumprimento"}, {"MOKUSO","Meditação (Fechar os olhos e manter silêncio)"}, {"ZA-REI","Cumprimento ajoelhado"}, {"RITSU-REI","Cumprimento em pé"}, {"SHI-HAN","Mestre"}, {"SENSEI","Professor"}, {"SEITÔ","Aluno"}, {"DÔO-HAI","Colegas"}, {"NINTAI","Perserverança"}, {"DORYOKU","Esforço, empenho"}, {"HISSHYÔ","Ei de vencer"}, {"KATANÁ","Espada"}, {"DAITÔO","Espada Maior"}, {"SHÔOTÔO","Espada Menor"}, {"TANTÔO","Punhal"}, {"BOKKEN","Espada de Madeira"} }; @Override public void onDestroyView() { super.onDestroyView(); ButterKnife.reset(this); }

我通过使用活动而不是片段解决了这个问题。以下代码工作正常：

在Android片段上实施搜索
