如何使用BaseAdapter在Custom ListView中进行过滤

Question

我似乎无法找到如何使我的自定义#!/usr/bin/env ruby string = "<li>Physical education sed<span class=\"meta\"><ul><li>15184745922</li></ul></span></li>" one, two = string.match(/<li>(.*?)<.*?<li>(.*?)</i).captures p one #=> "Physical education sed" p two #=> "15184745922" 工作。 我的getFilter()扩展了CustomAdapter，因为我已经知道它没有实现过滤，所以我需要自己做。我以各种方式尝试过，但没有成功。

问题1：工作方法是什么？ （如何正确实现过滤？）

Q2：如何更改BaseAdapter（！）以便过滤是一种自动功能？

请，不要忽视！ 非常感谢提前！

这是一段代码：

Main.java

CustomAdapter

CustomAdapter.java

    //  import ....

    public class MainActivity extends Activity  {

    ListView lv;
    Context context;
    EditText et;
    CustomAdapter adapter;
    View v;

    public  int [] Images=   {R.drawable.1,R.drawable.2,R.drawable.3,R.drawable.4};
    public  String [] NameList={"item1","item2","item3","item4"};

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        context=this;

        lv=(ListView) findViewById(R.id.listView);
        adapter = new CustomAdapter(this, fruitNameList,fruitImages);
        lv.setAdapter(adapter);

        et = (EditText)findViewById(R.id.editText);

        /**
         * Enabling Search Filter
         * */
        et.addTextChangedListener(new TextWatcher() {

            @Override
            public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) {
                // When user changed the Text
                MainActivity.this.adapter.getFilter().filter(cs); // !!!!getFilter() is not found I tried to write methods on my own but nothing worked
            }

            @Override
            public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
                                          int arg3) {
                // TODO Auto-generated method stub

            }

            @Override
            public void afterTextChanged(Editable arg0) {
                // TODO Auto-generated method stub
            }
        });



   }// end of onCreate

    public void onClick (View v) {
        switch (v.getId()) {
            case R.id.search:
                et.setVisibility(v.VISIBLE);
                et.setHint("Search names...");

                break;
        }
    }

    public void SearchFilterEnable() {
        /**
         * Enabling Search Filter
         * */
        et.addTextChangedListener(new TextWatcher() {

            @Override
            public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) {
                // When user changed the Text
                MainActivity.this.adapter.getFilter().filter(cs);
            }

            @Override
            public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
                                          int arg3) {
                // TODO Auto-generated method stub

            }

            @Override
            public void afterTextChanged(Editable arg0) {
                // TODO Auto-generated method stub
            }
        });

    }
}
