从Url获​​取图片无法解码流：fileNotFoundException

Question

我知道这个问题已被多次提出，但我已经尝试了许多解决方案而没有人工作。

在Android上，我试图从URL获取图像以将其放入图像视图中。 不幸的是，我收到以下错误：

E/BitmapFactory: Unable to decode stream: java.io.FileNotFoundException: http:/lorempixel.com/1920/1920/business (No such file or directory)

当我尝试从模拟器的浏览器访问此URL时，它可以正常工作。

我已经尝试过以下解决方案： Load image from url

How to get image from url website in imageview in android

how to set image from url for imageView

我的实际代码如下：

public class DownloadImage extends AsyncTask<String, Void, Bitmap> {

    ImageView imgView;

    public DownloadImage(ImageView imgView){
        this.imgView = imgView;
    }

    @Override
    protected Bitmap doInBackground(String... urls) {
        return download_Image(urls[0]);
    }

    @Override
    protected void onPostExecute(Bitmap result) {
        if (result != null)
            imgView.setImageBitmap(result);
    }


    private InputStream OpenHttpConnection(String urlString) throws IOException {
        InputStream in = null;
        int response = -1;

        URL url = new URL(urlString);
        URLConnection conn = url.openConnection();

        if (!(conn instanceof HttpURLConnection))
            throw new IOException("Not an HTTP connection");

        try {
            HttpURLConnection httpConn = (HttpURLConnection) conn;
            httpConn.setAllowUserInteraction(false);
            httpConn.setInstanceFollowRedirects(true);
            httpConn.setRequestMethod("GET");
            httpConn.connect();
            response = httpConn.getResponseCode();
            if (response == HttpURLConnection.HTTP_OK) {
                in = httpConn.getInputStream();
                Log.e("CON ", "HTTP connection OK");
            }
        } catch (Exception ex) {
            throw new IOException("Error connecting");
        }
        return in;
    }


    private Bitmap download_Image(String URL) {
        Bitmap bitmap = null;
        InputStream in = null;
        try {
            in = OpenHttpConnection("http://lorempixel.com/1920/1920/business");
            bitmap = BitmapFactory.decodeStream(in);
            in.close();
        } catch (IOException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }
        return bitmap;

    }
}

在主要活动中，我的代码是：

 ImageView img = (ImageView) findViewById(R.id.imageView);
 DownloadImage download = new DownloadImage(img);
 download.execute(url);

在清单中我添加了：

<uses-permission android:name="android.permission.INTERNET" />

我该怎么办？

Answer 1

这很完美：

String urlPath = "http://anyWebsite.com/images/12"
Bitmap bm = BitmapFactory.decodeStream((InputStream) new URL(urlPath).getContent());
myImageView.setImageBitmap(bm);
