TAB1代碼
public class Tab1 extends Fragment {
private ListView mListView;
private View rootView;
private ListviewContactAdapter adapter;
private ArrayList<ListviewContactItem> listContact;
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container,@Nullable Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.tab1, container, false);
mListView = (ListView) rootView.findViewById(R.id.list);
listContact = GetlistContact();
adapter=new ListviewContactAdapter(getActivity(), listContact);
mListView.setAdapter(adapter);
return rootView;
}
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
}
private ArrayList<ListviewContactItem> GetlistContact(){
ArrayList<ListviewContactItem> contactlist = new ArrayList<ListviewContactItem>();
ListviewContactItem contact = new ListviewContactItem();
contact.setPickUpPoint("xyz");
contact.setArea("xyz City");
contact.setLandmark("xyz xyz");
contact.setStreetName("xyz Road");
contactlist.add(contact);

CustomAdapter代碼

this.originaldata.addAll(results);
}
@Override

}
@Override
public Object getItem(int arg0) {
// TODO Auto-generated method stub
return listContact.get(arg0);
}

現在我想上實現搜索過濾器使用操作欄中的編輯文本顯示在選項卡片段中的列表視圖。請指導我如何做到這一點。只要用戶輸入文本，列表就應該開始顯示已過濾的項目。
