<ListView        android:id="@+id/search_word_list"        android:layout_width="match_parent"        android:layout_height="match_parent"/>

3. 主 .Java文件中

adapter = new SearchAdapter(this,R.layout.layout_search_list_item,        poiListList);    search_word_list.setAdapter(adapter);      search_word_list.setOnItemClickListener(this);

  private int last_item_position = -1;  private ImageView oldImageView;  @Override  public void onItemClick(AdapterView<?> arg0, View view, int position, long arg3) {          ImageView imageView = (ImageView) view.findViewById(R.id.search_listview_item_img);    imageView.setBackgroundResource(R.drawable.image_floor_color);

    //android 获取其他layout,如果仅仅还设置点击项目的改变其背景图片，点击positon可能会有重复     //之前点过的还原     if (last_item_position!=-1&& last_item_position != position) {           oldImageView.setBackgroundResource(R.drawable.image_floor_gary);//把上次选中的样式去掉      }     oldImageView = imageView;    last_item_position = position;    }  public class SearchAdapter extends ArrayAdapter<GetResultFromPOIName.PoiList> {    private int resourceId;    private ImageView imageView ;       public SearchAdapter(Context context, int textViewResourceId,        List<GetResultFromPOIName.PoiList> objects) {      super(context, textViewResourceId, objects);      resourceId = textViewResourceId;    }    @Override    public View getView(int position, View convertView, ViewGroup parent) {      PoiList poiList = getItem(position);       View view;      if (convertView == null) {        view = LayoutInflater.from(getContext()).inflate(resourceId, null);      } else {        view = convertView;      }         

      imageView = (ImageView) view.findViewById(R.id.search_listview_item_img);      if (last_item_position == position) {        //解决滑动listview的时候,选中的条目选中效果消失问题        // textView.setBackgroundColor(Color.BLUE);        imageView.setBackgroundResource(R.drawable.image_floor_color);      } else {        // textView.setBackgroundColor(Color.WHITE);        imageView.setBackgroundResource(R.drawable.image_floor_gary);      }      return view;    }
