我有一个使用 BaseAdapter 的自定义 listView。在其中显示电话簿联系人。在此 listView 中，两个文本框相应地显示名称和数字。现在我正在尝试在 listView 的搜索框顶部添加功能但我遇到了一些问题我不知道当我在 Eclipse 中看到我的 logcat 窗口时会发生什么然后我可以清楚地看到过滤后的列表但设备 listView 不是再改变。请按照我的代码如下：
package com.leaning.him;
public class ForHimActivity extends Activity {
private ListView contactList = null;
private LayoutInflater mInflater;
private String phoneNo;
private String contact;
private ContentResolver cr;
private Cursor cursor;
public ArrayList<String> aarr = new ArrayList<String>();
public ArrayList<String> aarr2 = new ArrayList<String>();
private static String ClickedNum;
private static boolean check;
private DBAdapter db;
CustomkListAdapter adapter;
EditText searchBar;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
searchBar = (EditText)findViewById(R.id.serchEditBox);
aarr.clear();
aarr2.clear();
adapter = new CustomkListAdapter(ForHimActivity.this);
contactList = (ListView)findViewById(R.id.facebookList);
contactList.setAdapter(adapter);
TextWatcher searchTextWatcher = new TextWatcher() {
public void onTextChanged(CharSequence s, int arg1, int arg2, int arg3) {
Log.v("","This is what you entred : "+s.toString());
adapter.getFilter().filter(s);
adapter.notifyDataSetChanged();
contactList.setAdapter(adapter);
}
public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
int arg3) {
// TODO Auto-generated method stub
}
public void afterTextChanged(Editable arg0) {
// TODO Auto-generated method stub
}
};
searchBar.addTextChangedListener(searchTextWatcher);
}
public class CustomkListAdapter extends BaseAdapter {
