android快速加载来自网址的图片(android fast load image from url)

我想将大约50张图片加载到listview中
这是我从url加载图片的代码

class ImageDownloader extends AsyncTask<String, Void, Bitmap> {
    ImageView bmImage;

    public ImageDownloader(ImageView bmImage) {
        this.bmImage = bmImage;
    }

    protected Bitmap doInBackground(String... urls) {
        String url = urls[0];
        Bitmap mIcon = null;
        try {
            InputStream in = new java.net.URL(url).openStream();
            mIcon = BitmapFactory.decodeStream(in);
        } catch (Exception e) {
            Log.e("Error", e.getMessage());
        }
        return mIcon;
    }

    protected void onPostExecute(Bitmap result) {
        bmImage.setImageBitmap(result);
    }
}

但图像加载速度慢。
我尝试使用Picasso库,但加载速度也很慢
如何更好地解决从url加载大量图像的问题。
对不起,我的英语不好
谢谢你的阅读

            mIcon = BitmapFactory.decodeStream(in);
        } catch (Exception e) {

您可以尝试将此添加到您的Android清单

<application android:hardwareAccelerated="true" ...>

我使用它来加载视频更快,它适用于我;)也许它也适合你


You could try to add this to your android manifest

<application android:hardwareAccelerated="true" ...>

i use this to load videos faster, and it works for me ;) Maybe it'll also work for you
