Java 带有自定义适配器的Android自定义AutoCompleteTextView

基本上，我希望在edittext中编写一些东西，然后将调用一个web http请求，该请求返回一个JSONObject，该JSONObject包含一个JSON数组，该数组包含其中的某个值。我需要用JSON对象的结果填充autocompletetextview附带的下拉列表

我可以做第二点，也就是说，我可以使用扩展arrayadapter的自定义适配器类来填充下拉列表中所需的值，如下所示。我的问题是第一位，如何覆盖AutoCompleteTextView，使其不显示从数组中筛选出的常量值，而是显示给它的值？我根本不希望它是可过滤的。以下是autocompletetextview的源代码

在返回自定义内部筛选器的PersonalAdapter override getFilter（）方法中，您必须实现它的两个方法：PerformFilter（）和publishResults（），PerformFilter在工作线程中运行，在这里您调用web请求，在publishResults中，只需调用clear（）和add（）项

谢谢。虽然，我也从这个问题中得到了帮助

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;
    }
