基本上，我希望在EditText上写东西，然后一个网页的HTTP请求将被调用，它返回一个JSONObject其中包含一个JSON数组，其中包含在它里面的地方的价值观。 我需要populat随从JSON对象的结果autocompletetextview下拉列表。
我可以做的第二位，也就是说我可以填充我需要通过扩展arrayadapter如u可以看到下面的自定义适配器类值的下拉列表。 我的问题是第一位的，我怎么能覆盖AutoCompleteTextView，使得它不显示我从数组常量过滤值，而让我发现，我给它的价值？ 我不希望它是过滤的。 下面是autocompletetextview的源代码http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android/4.0.4_r2.1/android/widget/AutoCompleteTextView.java#91
public class PersonAdapter extends ArrayAdapter
{
// we use the constructor allowing to provide a List of objects for the data
// to be binded.
public PersonAdapter(Context context, int textViewResourceId,
List objects) {
super(context, textViewResourceId, objects);
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// retrieve the Person object binded at this position
final Person p = getItem(position);
// A ViewHolder keeps references to children views to avoid unneccessary
// calls
// to findViewById() on each row.
ViewHolder holder;
// When convertView is not null, we can reuse it directly, there is no
// need
// to reinflate it. We only inflate a new View when the convertView
// supplied
// by ListView is null.
if (convertView == null) {
convertView = View.inflate(getContext(), R.layout.list_item, parent, false);
// Creates a ViewHolder and store references to the two children
// views
// we want to bind data to.
holder = new ViewHolder();
holder.textName = (TextView) convertView
.findViewById(R.id.textName);
holder.textEmail = (TextView) convertView
.findViewById(R.id.textEmail);
holder.picture = (ImageView) convertView.findViewById(R.id.image);
holder.picture.setFocusable(false);
holder.picture.setFocusableInTouchMode(false);
convertView.setTag(holder);
} else {
// Get the ViewHolder back to get fast access to the TextView
// and the ImageView.
holder = (ViewHolder) convertView.getTag();
}
// Bind the data efficiently with the holder.
holder.textName.setText(p.getName());
holder.textEmail.setText(p.getEmail());
holder.picture.setImageResource(p.getResImage());
//click on the picture
holder.picture.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(getContext(),
"Clicked on " + p.getName() + "'s picture",
Toast.LENGTH_SHORT).show();
}
});
return convertView;
}
/**
*
* Inner holder class for a single row view in the ListView

*/
static class ViewHolder {
TextView textName, textEmail;
ImageView picture;
}
}
