Bonjour à tous,

Je souhaite télécharger une image d'internet afin de la placer dans un ImageView.

J'ai donc le code :

public static Bitmap telechargerImage(String url){
       Bitmap bm = null;
       try{
           URL aURL = new URL(url);
           URLConnection conn = aURL.openConnection();
           conn.connect();
           InputStream is = conn.getInputStream();
           BufferedInputStream bis = new BufferedInputStream(is);
           bm = BitmapFactory.decodeStream(bis);
           bis.close();
           is.close();
           Log.e("dl","OK");
       } catch(IOException e){
           Log.e("Erreur","Erreur IO");
       }
       return bm;
   }

Qui est appelé dans le onCreate par :

((ImageView)findViewById(R.id.Imagedlduweb)).setImageBitmap(telechargerImage("http://www.google.fr/intl/fr_fr/images/logo.gif"));

et j'ai les warning suivant :

05-05 13:46:17.071: WARN/ResourceType(1465): No package identifier when getting value for resource number 0x00000001

Du coup l'image ne s'affiche pas...

Si quelqu'un a la solution je suis preneur !

Merci par avance pour votre aide.

Re bonjour à tous,

Maintenant que j'arrive à télécharger mon image correctement, je souhaite l'intégrer à une gallery.

J'ai suivit le tuto de Google sur le sujet, ce qui me permet d'avoir un truc plutot sympa mais qui ne prend en charge que les image contenue dans mon drawable...

Voici le code :

public class ImageAdapter extends BaseAdapter {
       int mGalleryItemBackground;
       private Context mContext;
       int t;
       private Integer[] mImageIds = {

               R.drawable.clio,
               R.drawable.alfa147,
               R.drawable.a4,
       };


       public ImageAdapter(Context c) {
           mContext = c;

       }

       public int getCount() {
           return mImageIds.length;
       }

       public Object getItem(int position) {
           return position;
       }

       public long getItemId(int position) {
           return position;
       }

	@Override
	public View getView(int position, View convertView, ViewGroup parent) {
		ImageView i = new ImageView(mContext);


           i.setImageResource(mImageIds[position]);
          // i.setImageBitmap(telechargerImage("http://filer.kiloutou.fr//Upload/Materiel/Image140/camben_140.gif"));
           i.setLayoutParams(new Gallery.LayoutParams(150, 100));
           i.setScaleType(ImageView.ScaleType.FIT_XY);
           i.setBackgroundResource(mGalleryItemBackground);

           return i;
	}
   }

Lorsque je laisse la ligne : 

i.setImageBitmap(telechargerImage("http://filer.kiloutou.fr//Upload/Materiel/Image140/camben_140.gif"));

Sa met bien l'image mais à la place des 3 autres. C'est à dire que l'image apparait 3 fois de suite.

Si quelqu'un a une solution ...

Merci par avance
