    		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");

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

Si quelqu'un a la solution je suis preneur !

Merci par avance pour votre aide.

BitmapFactory ?

**Flow07** · 05/05/2010, 16h10

Oui pourquoi ca ne va pas ?

Si tu as une meilleur solution ou même une solution différente mais qui marche je suis preneur

**amithral** · 05/05/2010, 16h18

je n'en sais rien c'est quoi ?

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

Il n'y a pas de methode setImageBitmap() dans la classe ImageView.
Tu compiles le bon code ?

**Flow07** · 05/05/2010, 16h47

J'ai trouvé la solution.
Oui je compile le bon code et si il existe bien la fonction setImageBitmap() dans la classe ImageView.

Merci quand même

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 :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

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 :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

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
