Question

我正在调用UIL的displayImage方法，但它不接受图片URI。这是我的getView代码。我收到了错误：

UnsupportedOperationException: UIL doesn't support scheme(protocol) by default [2130837504]. You should implement this support yourself (BaseImageDownloader.getStreamFromOtherSource(...))

@Override
    public View getView(int position, View convertView, ViewGroup parent) {

        final ViewHolder holder;

        if (convertView == null) {

            convertView = mLayoutInflater.inflate(R.layout.grid_view_card_layout, parent, false);
            holder = new ViewHolder();
            holder.participantName = (TextView) convertView.findViewById(R.id.grid_model_name);
            holder.participantCountry = (TextView) convertView.findViewById(R.id.grid_country_name);
            holder.participantImage = (ImageView) convertView.findViewById(R.id.grid_model_image);
            holder.progressBar = (ProgressBar) convertView.findViewById(R.id.progress);
            convertView.setTag(holder);

        } else {
            holder=(ViewHolder)convertView.getTag();
        }

        applyTypeFace(convertView);

        holder.participantName.setText(ParticipantName[position]);
        holder.participantCountry.setText(ParticipantCountry[position]);
        //holder.participantImage.setImageResource(ImageId[position]);

        //Here lies the problem
        ImageLoader.getInstance()
                .displayImage(String.valueOf(ImageId[position]), holder.participantImage);

        return convertView;
    }

请帮忙吗？

Answer 1

检查您的图片字符串，它应该来自readme

String imageUri = "assets://image.png"; // from assets
String imageUri = "drawable://" + R.drawable.image; // from drawables (only images, non-9patch)

Answer 2

您必须使用“drawable：//”+可绘制资源的ID

示例：

ImageLoader.getInstance().displayImage("drawable://" + R.drawable.icon_teste,holder.participantImage);

如果你想通过它的名字而不是id来获取drawable，你可以使用它来获取它的标识符：

int id = getContext().getResources().getIdentifier(ICON_NAME, "drawable", getContext().getPackageName());

无法使用Universal Image Loader从drawable加载GridView的图像
