    		URLConnection conn = aURL.openConnection();
    		conn.connect();
    		InputStream is = conn.getInputStream();
    		BufferedInputStream bis = new BufferedInputStream(is);
    		bm = BitmapFactory.decodeStream(bis);
    		bis.close();

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

Si quelqu'un a la solution je suis preneur !

Merci par avance pour votre aide.

BitmapFactory ?

Oui pourquoi ca ne va pas ?

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

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 ? :lol:

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 :

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:

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

Salut,

Je ne comprends pas bien ton problème.
Code:

1 2 3 i.setImageResource(mImageIds[position]); // i.setImageBitmap(telechargerImage("http://filer.kiloutou.fr//Upload/Materiel/Image140/camben_140.gif"));
Si tu fonctionnes avec la ligne 1, tu as une image différentes pour chaque ligne de ta liste, par contre si tu fonctionnes avec la ligne 2, tu as la même image pour chaque ligne. C'est bien ça ?

Non en fait si je laisse cette ligne sans la mettre en commentaire, toutes les images sont les mêmes (celle de cette ligne). Par contre, si je ne met pas cette ligne, rien ne s'affiche.

En fait c'est ici que je veux mettre l'image :
Code:

1 2 3 4 5 6 7 private Integer[] mImageIds = { R.drawable.clio, R.drawable.alfa147, R.drawable.a4, ICI };
Comment faire pour afficher cette image dans la Gallery. ou plutôt :
Comment afficher une image télécharger du web dans une gallery ?

Merci par avance,

Personne pour un petit coup de main ?
J'ai la possibilité de faire ça en dur (mettre directement les images dans le .apk) mais se serait vraiment mieux de pouvoir les récupérer directement. Notamment en cas de mis à jour ou de modification du site web...

Si quelqu'un avait une solution se serait vraiment sympa !

Merci par avance pour vos réponses.

Salut,

Tu peux faire quelques choses ça :

class monActivite 
{
 
  ArrayList<URI> mListeImage;
 
  public void onCreate() {
     // tu appelles une méthode pour télécharger tous tes fichiers images sur ta carte SD
     //Tu stockes les chemins de tes images dans une liste
     mListeImage  = getAllImage();
     //Tu initialise ton adapter perso avec cette liste d'images
     ImageAdapter adp = new ImageAdapter(this, mListeImage);
     /// tu donnes cet adapter à ta liste
  }
}

(tu noteras que le code est plus proche de l'algorithme que du java.... :lol:)

et du coup après dans get getView de ton adapter, tu initialises chaque image avec

Code:

1
2
 
i.setImageURI(mListeImage[position]);

Merci beaucoup je vais essayer ça !

Bon Week end !
