I am downloading an image from url, but the image is not changed after the download is complete. I am entering code below, anybody experienced the same? Java file public class MyIm

Solution 1:

Please Use below code for download and display image into imageview.

publicclassimageextendsActivity {
    /** Called when the activity is first created. */@OverridepublicvoidonCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Bitmapbitmap= DownloadImage("http://www.gophoto.it/view.php?i=https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjat4DPlVzROqw45aAF_WXGyNrAbQbm1mT06hC7z1gOZ7hPt9TgFMo8hSLV2Vf2ILWBtWOpHiCVjUNMuOmcHd23XhqxBOyrQGlyjMLE5P9KVAzCGOpELrc_jV71jTd4VaaClMJGcFOxmAnj/s1600/Sachin+Tendulkar.png");
        ImageViewimg= (ImageView) findViewById(R.id.img);
        img.setImageBitmap(bitmap);
    }

    private InputStream OpenHttpConnection(String urlString)throws IOException {
        InputStreamin=null;
        intresponse= -1;

        URLurl=newURL(urlString);
        URLConnectionconn= url.openConnection();

        if (!(conn instanceof HttpURLConnection))
            thrownewIOException("Not an HTTP connection");

        try {
            HttpURLConnectionhttpConn= (HttpURLConnection) conn;
            httpConn.setAllowUserInteraction(false);
            httpConn.setInstanceFollowRedirects(true);
            httpConn.setRequestMethod("GET");
            httpConn.connect();
            response = httpConn.getResponseCode();
            if (response == HttpURLConnection.HTTP_OK) {
                in = httpConn.getInputStream();
            }
        } catch (Exception ex) {
            thrownewIOException("Error connecting");
        }
        return in;
    }

    private Bitmap DownloadImage(String URL) {
        Bitmapbitmap=null;
        InputStreamin=null;
        try {
            in = OpenHttpConnection(URL);
            bitmap = BitmapFactory.decodeStream(in);
            in.close();
        } catch (IOException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }
        return bitmap;
    }
}

Solution 2:

Following code working with the following url but its not working with your url.the problem is with your image size.Try with another url it will work.

publicclassMyImgActivityextendsActivity {
    /** Called when the activity is first created. */@OverridepublicvoidonCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        ImageViewimgView=(ImageView)findViewById(R.id.imageView1);
        URLurl=null;
        Bitmapbmp=null;
        try {
            url = newURL("http://www.seobook.com/images/smallfish.jpg");
            bmp = BitmapFactory.decodeStream(url.openConnection().getInputStream());
        } catch (MalformedURLException e) {

        }catch (IOException e) {

        }
       imgView.setImageBitmap(bmp); 
      }

    }

Solution 3:

try
  {

   URLmurl=newURL(url)
  URLConnectionucon= murl.openConnection();
  InputStreamis= ucon.getInputStream();
   Drawabled= Drawable.createFromStream(is, "src name");
   return d;
  }catch (Exception e) {
   System.out.println("Exc="+e);
   returnnull;
  }

use this cose inside your download method and if the connection speed is slow use thread to donwload and hanlder to post the image...as explained by @Hiren

Solution 4:

try below code,

just change your URL to,

URL

onCreate

newThread(newRunnable() {

        @Overridepublicvoidrun() {
            // TODO Auto-generated method stub
            drawable = LoadImageFromWebOperations("https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjat4DPlVzROqw45aAF_WXGyNrAbQbm1mT06hC7z1gOZ7hPt9TgFMo8hSLV2Vf2ILWBtWOpHiCVjUNMuOmcHd23XhqxBOyrQGlyjMLE5P9KVAzCGOpELrc_jV71jTd4VaaClMJGcFOxmAnj/s1600/Sachin+Tendulkar.png");
            handler.sendEmptyMessage(0);
        }
    }).start();

set image after downloading image using handler

Handlerhandler=newHandler(){
    @OverridepublicvoidhandleMessage(android.os.Message msg) {
        imgView.setImageDrawable(drawable);
        Log.i("System out","after set the image...");
    }
};

Hope help you...
