使用简单光标适配器时如何在列表项中添加两个图像。我尝试通过扩展 SimpleCursorAdapter 类来覆盖 setViewImage。对于单个图像没有问题。但是如何添加两个图像？

MyFragment.java：

geoAdapter = new MySimpleCursorAdapter(getActivity().getApplicationContext(), R.layout.listitem_cdf_geolist, c1, new String[] {DBConstants.LATITUDE,DBConstants.LONGITUDE,DBConstants.TOLERANCE,DBConstants.IMEI,DBConstants.IMEI}, new int[] {R.id.li_cdf_tv_latitude,R.id.li_cdf_tv_longitude,R.id.li_cdf_tv_tolerance,R.id.li_cdf_icon_georemove,R.id.li_cdf_icon_geoedit},0);
geoList.setAdapter(geoAdapter);

在 MySimpleCursorAdapter.java 文件中：

@Override
    public void setViewImage(ImageView imageView, String imei) { 
        Log.i("simple", "text->"+imei);


        //Here how to set two images and set imei as tag for those images

        imageView.setTag(imei);
        imageView.setImageResource(R.drawable.action_edit);

        final ImageView myimageView=imageView;

        imageView.setOnClickListener(new OnClickListener(){
            @Override
            public void onClick(View v) {
              Log.i("simple", "clicked");
              String selectedIMEI = v.getTag().toString();
            }
        });

    }

列表项布局 XML 文件：

<?xml version="1.0" encoding="utf-8"?>

更新 ：

我试图超越 bindview。为每个列表项显示的图像。但是，如果我为每个图像设置标签，则将相同的标签应用于所有图像。还删除图标 onclick 事件仅在单击编辑和删除图像时触发。如何

@Override
    public void bindView(View view, Context context, Cursor c) {
        super.bindView(view, context, c);
        ImageView geoEditIcon = (ImageView)view.findViewById(R.id.li_cdf_icon_geoedit);
        geoEditIcon.setImageResource(R.drawable.action_editvehicle);
        geoEditIcon.setTag(c.getString(c.getColumnIndex(DBConstants.IMEI)));

    geoEditIcon.setOnClickListener(new OnClickListener(){
        @Override
        public void onClick(View v) {
          Log.i("geolist", "geoRemoveIcon clicked");
          String selectedIMEI = v.getTag().toString();
          Log.i("geolist", "geoRemoveIcon selectedIMEI->"+selectedIMEI);
        }
    });

    ImageView geoRemoveIcon = (ImageView)view.findViewById(R.id.li_cdf_icon_georemove);
    geoRemoveIcon.setImageResource(R.drawable.action_removevehicle);
    geoRemoveIcon.setTag(c.getString(c.getColumnIndex(DBConstants.IMEI)));

    geoRemoveIcon.setOnClickListener(new OnClickListener(){
        @Override
        public void onClick(View v) {
          Log.i("geolist", "geoRemoveIcon clicked");
          String selectedIMEI = v.getTag().toString();
          Log.i("geolist", "geoRemoveIcon selectedIMEI->"+selectedIMEI);
        }
    });
}

Try to override method bindView. This will look like:

@Override
public void bindView(View view, Context context, Cursor cursor) {
ImageView frst = (ImageView )view.findViewById(R.id.li_cdf_icon_georemove);
ImageView scnd = (ImageView )view.findViewById(R.id.li_cdf_icon_geoedit);
...
}
