Question

我正在尝试从Web服务中检索图像和文本列表。我首先使用简单适配器编码将图像输入到列表中。图像显示应用程序显示错误，在Logcat中出现以下错误...

这是适配器中的编码......

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);

加载图片......

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;
     }

请告诉我如何解决错误....

Answer 1

您收到OOM错误，因为您的Bitmap占用了太多内存。看看这是否有帮助：Handling large Bitmaps。将图像向下采样到原始大小的一半可能仍会导致图像对于运行时来说太大。

内存不足错误
