内存不足错误

Question

我正在尝试从web服务检索图像和文本的列表。我首先使用Simple Adapter对图像进行编码，将其添加到列表中。图像正在显示应用程序显示错误，并且在Logcat中发生以下错误...

下面是适配器中的代码...

final ImageView imageView = (ImageView) rowView.findViewById(R.id.image);
        AsyncImageLoaderv asyncImageLoader=new AsyncImageLoaderv();
        Bitmap cachedImage = asyncImageLoader.loadDrawable(imgPath, new AsyncImageLoaderv.ImageCallback() {
            public void imageLoaded(Bitmap imageDrawable, String imageUrl) {

                imageView.setImageBitmap(imageDrawable);
            }
            });
        imageView.setImageBitmap(cachedImage);

要加载图像...

public static Bitmap loadImageFromUrl(String url) {
            InputStream inputStream;Bitmap b;
        try {

            inputStream = (InputStream) new URL(url).getContent();
            BitmapFactory.Options bpo=  new BitmapFactory.Options();
            bpo.inSampleSize=2;
             b=BitmapFactory.decodeStream(inputStream, null,bpo );
             return b;
        } catch (IOException e) {
                throw new RuntimeException(e);
            }
           //return null;
     }  

请告诉我如何修复错误....

因为位图占用了太多内存，所以出现了OOM错误。看看这能不能帮上忙：Handling large Bitmaps。向下采样图像到其原始大小的一半可能仍然会导致图像对于运行时来说太大。
