如何通过单击列表项右上角图像来更改列表视图项图像资源？

Question

我正在处理更改列表视图项上的图像资源的任务，方法是点击该图像，这是列表视图项[不点击列表视图项 ]。这就像使用图像资源突出显示列表视图项一样。 我在这里提交我的Base适配器类代码。

DashListAdapter：

public class DashListAdapter extends BaseAdapter {

    public static ProgressDialog progress;
    public static ListView dashListView;
    Context c;
    /* String fromdate_formated = "";
     String todate_formated = "";*/
    private LayoutInflater inflater;
    private List<DashListModel> dashRowList;


    public DashListAdapter(Context c, List<DashListModel> dashRowList, ListView dashListView) {
        this.c = c;
        this.progress = new ProgressDialog(c);
        this.dashListView = dashListView;
        this.dashRowList = dashRowList;
    }

    public DashListAdapter(Context c, List<DashListModel> dashRowList) {
        this.c = c;
        this.progress = new ProgressDialog(c);
        this.dashRowList = dashRowList;
    }
   /* public DashListAdapter(){

    }*/

    @Override
    public int getCount() {
        Log.e("size()", "size------>" + dashRowList.size());
        return this.dashRowList.size();
    }

    @Override
    public Object getItem(int position) {
        return dashRowList.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @TargetApi(Build.VERSION_CODES.LOLLIPOP)
    @Override
    public View getView(final int position, View convertView, ViewGroup parent) {
        final ViewHolder dashHolder;
        if (inflater == null)
            inflater = (LayoutInflater) c
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        if (convertView == null)
            convertView = inflater.inflate(R.layout.dashboard_jobdetails_list, null);


        Log.e("get pos", "get pooooossss---->" + dashRowList.get(position));
        final DashListModel dashModel = dashRowList.get(position);
        dashHolder = new ViewHolder(convertView);

        dashHolder.bookmark_img.setOnClickListener(new View.OnClickListener() {

            public void onClick(View view) {

                if (dashModel.getDashIsBookmarked().equalsIgnoreCase("0")) {
                    Log.e("imgchange", " imgchange");
                    dashHolder.bookmark_img.setImageResource(R.drawable.bookmark);
                    Map<String, String> params = new HashMap<String, String>();
                    params.put("candidate_id", SessionStores.getBullHornId(c));
                    params.put("joborder_id", dashModel.getDashId());
                    //new BookMarkTaskAdd(c, params);
                    notifyDataSetChanged();
                }
                if (dashModel.getDashIsBookmarked().equalsIgnoreCase("1")) {
                    Log.e("imgchange", " imgchange");
                    dashHolder.bookmark_img.setImageResource(R.drawable.blue_tag_img);
                    Map<String, String> params = new HashMap<String, String>();
                    params.put("candidate_id", SessionStores.getBullHornId(c));
                    params.put("joborder_id", dashModel.getDashId());
                   // new BookMarkTaskDelete(c, params);
                    notifyDataSetChanged();
                }

            }
        });

        dashHolder.dash_company_name.setText(dashModel.getDashCompanyName());
        dashHolder.dash_position_name.setText(dashModel.getDashJobPosition());
        dashHolder.dash_posted_date.setText(dashModel.getPostedDate());
        dashHolder.dash_job_description.setText(dashModel.getDashJobDescription());
        dashHolder.dash_salary.setText(dashModel.getDashSalary() + " - " + dashModel.getDashEndSalary());
        dashHolder.dash_available_date.setText(dashModel.getFromDate() + " - " + dashModel.getEndDate());
        dashHolder.book_jobCity.setText(dashModel.getDashJobCity());
        Log.e("BookMa", " Book!!!!!!!!!!!!!!!" + dashModel.getDashIsBookmarked());
        if (dashModel.getDashIsBookmarked().equalsIgnoreCase("1")) {
            Log.e("BookMark 1", " BookMaerk 1");
            dashHolder.bookmark_img.setImageResource(R.drawable.bookmark);
        } else if (dashModel.getDashIsBookmarked().equalsIgnoreCase("0")) {
            Log.e("BookMark 00", " BookMaerk 00");
            dashHolder.bookmark_img.setImageResource(R.drawable.blue_tag_img);
        }

        return convertView;
    }


    static class ViewHolder {

        @Bind(R.id.book_company_name)
        TextView dash_company_name;
        @Bind(R.id.book_position_name)
        TextView dash_position_name;
        @Bind(R.id.book_posted_date)
        TextView dash_posted_date;
        @Bind(R.id.book_job_description)
        TextView dash_job_description;
        @Bind(R.id.book_salary)
        TextView dash_salary;
        @Bind(R.id.book_available_date)
        TextView dash_available_date;
        @Bind(R.id.book_jobCity)
        TextView book_jobCity;
       /* @Bind(R.id.book_jobState)
        TextView book_jobState;*/

        @Bind(R.id.sideView)
        ImageView sideView;

        @Bind(R.id.bookmark_img)
        ImageView bookmark_img;

        @Bind(R.id.noificationLayout)
        RelativeLayout noificationLayout;
        @Bind(R.id.notificationCount)
        TextView notificationCount;

        private RelativeLayout.LayoutParams viewLayParams;

        public ViewHolder(View view) {
            ButterKnife.bind(this, view);


        }
    }


}

以上代码，同时点击 dashHolder.bookmark_img ，图片资源必须更改默认图片和相应的 书签API实施 也可以将书签结果更新到服务器。在我的代码中，更改图像存在问题。请注意我的代码，并建议我得到解决方案。提前感谢您的时间和考虑。
