android显示两种情况的列表数据,Android AutoCompleteTextView包含来自Web服务的数据,显示建议列表时出现问题...

一个我无法解决的问题.

我想要实现的目标:

在Web服务调用中显示的AutoCompleteTextView中显示建议.最终结果应如下所示:

到目前为止我做了什么:

在我的布局中,我有一个像这样的AutoCompleteTextView

android:id="@+id/txtAutoSearch"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:selectAllOnFocus="true"

android:singleLine="true" />

在我的活动中我有这个:

autoCompleteAdapter = new AdapterAutoComplete(context, ????? what should I have here?????, null);

autoCompleteAdapter.setNotifyOnChange(true);

txtAutoSearch.setAdapter(autoCompleteAdapter);

txtAutoSearch.addTextChangedListener(new TextWatcher() {

private boolean shouldAutoComplete = true;

@Override

public void onTextChanged(CharSequence s, int start, int before, int count) {

shouldAutoComplete = true;

}

@Override

public void beforeTextChanged(CharSequence s, int start, int count, int after) {

}

@Override

public void afterTextChanged(Editable s) {

if (shouldAutoComplete) {

new GetAutoSuggestionsTask().execute(s.toString());

}

}

});

AsyncTask非常简单,onPostExecute我使用从webservice返回的数据设置适配器

autoCompleteAdapter = new AdapterAutoComplete(context, ????? what should I have here?????,result);

txtAutoSearch.setAdapter(autoCompleteAdapter);

适配器看起来像这样:

public class AdapterAutoComplete extends ArrayAdapter {

private Activity activity;

private List lstPersons;

private static LayoutInflater inflater = null;

public AdapterAutoComplete(Activity a, int textViewResourceId, List lst) {

super(a, textViewResourceId, lst);

activity = a;

lstPersons = lst;

inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

}

public int getCount() {

return lstPersons.size();

}

public long getItemId(int position) {

return position;

}

public Person getCurrentPerson(int position) {

return lstPersons.get(position);

}

public void removeItem(int position) {

lstPersons.remove(position);

}

public static class ViewHolder {

public TextView txtName;

public TextView txtProfession;

}

@Override

public View getView(int position, View convertView, ViewGroup parent) {

View vi = convertView;

ViewHolder holder;

if (convertView == null) {

vi = inflater.inflate(R.layout.people_list_item, null);

Utils.overrideFonts(activity, vi);

holder = new ViewHolder();

holder.txtName = (TextView) vi.findViewById(R.id.txtName);

holder.txtProfession = (TextView) vi.findViewById(R.id.txtProfession);

vi.setTag(holder);

} else {

holder = (ViewHolder) vi.getTag();

}

Person o = lstPersons.get(position);

if (o.name != null) {

holder.txtName.setText(o.name);

} else {

holder.txtName.setText("N/A");

}

if (o.profession != null) {

holder.txtProfession.setText(o.profession);

} else {

holder.txtProfession.setText("N/A");

}

return vi;

}

}

实际发生了什么:

Web服务返回我需要的列表,因此数据可用

在适配器中,getView似乎没有执行,所以我猜其中有一些错误.

我的值没有显示建议列表

对于textViewResourceId,我不知道我需要什么适配器构造函数.我究竟做错了什么？我被困了请求帮助.
