Android双层Adapter的使用（在ListView中添加Spinner）

最近做了一个Android的地图软件，用到了Adapter的嵌套，小结如下

 

需要实现的效果如下：

 

      为了下拉列表Spinner中添加ImageView，本人使用了自定义Adapter子类的方法，为下拉列表添加自定义的View，类IconsAdapter的声明如下  

  1 package com.Android.Baidu.Layers;
  2 
  3 import com.Android.Baidu.navisurveytest.MainActivity;
  4 import com.Android.Baidu.navisurveytest.R;

  7 import android.view.View;
  8 import android.view.ViewGroup;
  9 import android.view.ViewGroup.LayoutParams;
 10 import android.widget.BaseAdapter;
 11 import android.widget.ImageView;
 12 import android.widget.LinearLayout;

 15 public class IconsAdapter extends BaseAdapter {
 16 
 17     @Override
 18     public int getCount() {
 19         // TODO Auto-generated method stub
 20         return 6;///////////////////////////////////////////////////////////////////
 21     }

 23     @Override
 24     public Object getItem(int position) {
 25         // TODO Auto-generated method stub
 26         return null;
 27     }

 29     @Override
 30     public long getItemId(int position) {
 31         // TODO Auto-generated method stub

 41         imageView.setLayoutParams(new LayoutParams(40, 40));
