Android微调器不滚动，为什么？

Question

我的应用中有一个微调器，您可以在其中选择类别和子类别。 它在过去工作得很完美，但由于我在应用程序中做了很多修改，旋转器不再滚动，不仅仅是一个微调器，而是这个布局中的所有微调器（抽屉菜单）。

这是包含微调器的右侧菜单抽屉的XML：

这是微调器适配器：

package com.chno.v1;

import android.app.Activity;
import android.content.Context;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.TextView;

import java.util.ArrayList;
import java.util.List;

/**
 * List view
 */

public class SpinnerAdapter extends ArrayAdapter<ItemDate> {

private int groupid;
private Activity context;
private ArrayList<ItemDate> list;
private LayoutInflater inflater;

public SpinnerAdapter(Activity context, int groupid, int id, ArrayList<ItemDate> list) {
    super(context,id, list);
    this.list = list;
    inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    this.groupid = groupid;
}

public View getView(int position, View convertView, ViewGroup parent) {
    View itemView = inflater.inflate(groupid,parent,false);
    ImageView imageView = (ImageView)itemView.findViewById(R.id.img);
    ItemDate item = list.get(position);
    if(item != null) {
        if(item.getType() != null) {
            if (item.getType().equals("sub_category")) {
                imageView.setVisibility(View.GONE);
            } else {
                imageView.setImageResource(item.getImageId());
            }
        } else {
            imageView.setImageResource(item.getImageId());
        }
    } else {
        imageView.setImageResource(item.getImageId());
    }
    imageView.setImageResource(item.getImageId());
    TextView textView = (TextView)itemView.findViewById(R.id.txt);
    textView.setText(item.getText());
    return itemView;
}

public View getDropDownView(int position, View convertView, ViewGroup
        parent) {
    return getView(position,convertView,parent);
}

}

问题是我可以从微调器中选择项目，但我无法向下滚动以获取更多项目。

以下是填充微调器的代码：

        JSONObject result = config.getCategories();
        Iterator<String> iter = result.keys();
        while (iter.hasNext()) {
            String key = iter.next();
            try {
                JSONObject cat = result.getJSONObject(key);
                String category = cat.getString("n");
                int drawable = helper.getCategoryDrawable(Integer.parseInt(key));
                Log.e("" + category, "" + key);
                list.add(new ItemDate("category", category, Integer.parseInt(key), drawable));
                JSONObject subs = cat.getJSONObject("l");
                Iterator<String> it2 = subs.keys();
                while (it2.hasNext()) {
                    String sub_key = it2.next();
                    JSONObject sub_category = subs.getJSONObject(sub_key);
                    String name = sub_category.getString("n");
                    Log.e("FFROM LIST", "" + name);
                    list.add(new ItemDate("sub_category", name, Integer.parseInt(sub_key), Integer.parseInt(key), R.drawable.tool_icon_filter));
                }
            } catch (JSONException e) {
                Log.e("JSONException", e.getMessage());
                e.printStackTrace();
            }
        }

        Spinner sp=(Spinner)findViewById(R.id.spinner1);
        SpinnerAdapter adapter=new SpinnerAdapter((Activity) context, R.layout.sub_select_item, R.id.txt, list);
        sp.setAdapter(adapter);
        sp.setFocusable(true);
        sp.setFocusableInTouchMode(true);

我该如何解决这个问题？感谢。
