问题描述

这个搜索功能怎么实现呀？求大神帮忙指点，谢谢！下面是代码

主程序的：
public class MainActivity extends Activity {
private ListView listview;
private MedicineService medicineservice;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
medicineservice = new MedicineService(this);

    listview = (ListView) this.findViewById(R.id.listview);    Button button = (Button)findViewById(R.id.mybutton);    button.setOnClickListener(new ButtonClickListener());}public class ButtonClickListener implements View.OnClickListener{EditText txt = (EditText) findViewById(R.id.myEdit);private String qwe = txt.getText().toString(); public void onClick(View v) {    List<Medicine> medicines = medicineservice.getScrollData(0 10);    medicineservice.find(this.qwe);    MedicineAdapter adapter = new MedicineAdapter(this medicines R.layout.item);    List<HashMap<StringObject>> data = new ArrayList<HashMap<StringObject>>();    for(Medicine medicine : medicines){        HashMap<StringObject> item = new HashMap<StringObject>();        item.put(""name"" medicine.getName());        item.put(""ename"" medicine.getEname());        item.put(""content"" medicine.getContent());        item.put(""id"" medicine.getId());        data.add(item);    }    //SimpleAdapter adapter = new SimpleAdapter(thisdataR.layout.itemnew String[]{""name""ename""content""} new int[]{R.id.nameR.id.enameR.id.content});    listview.setAdapter(adapter);}public LayoutInflater getSystemService(String layoutInflaterService) {    return null;}}

}

自定义适配器的：
public class MedicineAdapter extends BaseAdapter {
private List medicines;//绑定的数据
private int resource;//绑定的界面
private LayoutInflater inflater;
public MedicineAdapter(ButtonClickListener buttonClickListenerList medicinesint resource ) {
this.medicines = medicines;
this.resource = resource;
inflater = (LayoutInflater) buttonClickListener.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}

public int getCount() {    return medicines.size();//得到总数}public Object getItem(int position) {    return medicines.get(position);}public long getItemId(int position) {    return position;}public View getView(int position View convertView ViewGroup parent) {    if(convertView==null){        convertView = inflater.inflate(resource null);    }    TextView nameView = (TextView) convertView.findViewById(R.id.name);    TextView enameView = (TextView) convertView.findViewById(R.id.ename);    TextView contentView = (TextView) convertView.findViewById(R.id.content);    Medicine medicine = medicines.get(position);    //下面代码实现数据绑定    nameView.setText(medicine.getName());    enameView.setText(medicine.getEname());    contentView.setText(medicine.getContent());    return convertView;}

}

public LayoutInflater getSystemService这个该怎么写？？？谢谢各位大神。
