如何使用基本适配器创建搜索选项？这是我尝试过的示例代码......请建议
public class ListViewAdapter extends BaseAdapter
{ //To create an adapter we have to extend BaseAdapter instead of Activity, or whatever.
private Activity activity;
private ArrayList<HashMap<String, String>> data;
private static LayoutInflater inflater=null;
public ListViewAdapter(Activity a, ArrayList<HashMap<String, String>> d) {
activity = a;
data=d;
inflater = (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
public int getCount() { //get the number of elements in the listview
return data.size();
}
public Object getItem(int position) { //this method returns on Object by position
return position;
}
public long getItemId(int position) { //get item id by position
return position;
}
public View getView(int position, View convertView, ViewGroup parent) { //getView method is the method which populates the listview with our personalized rows
View vi=convertView;
if(convertView==null)
vi = inflater.inflate(R.layout.layout1, null); //every item in listview uses xml "listview_row"'s design
TextView id = (TextView)vi.findViewById(R.id.textView1); //Here are two textviews in the listview_row xml file
TextView name = (TextView)vi.findViewById(R.id.textView2); // You can enter anything you want, buttons, radiobuttons, images, etc.
TextView loc = (TextView)vi.findViewById(R.id.textView3);
TextView desc = (TextView)vi.findViewById(R.id.textView4);
TextView status = (TextView)vi.findViewById(R.id.textView5);
HashMap<String, String> hash = new HashMap<String, String>(); //We need a HashMap to store our data for any item
hash = data.get(position);
id.setText(hash.get(SaActivity.KEY_ACCOUNTNUMBER)); //We personalize our row's items.
name.setText(hash.get(SaActivity.KEY_NAME));
loc.setText(hash.get(SaActivity.KEY_STATUS));
desc.setText(hash.get(SaActivity.KEY_DESC));
status.setText(hash.get(SaActivity.KEY_NAME));
return vi;
}
}
