J'ai essayé de comprendre pourquoi cela ne fonctionne pas. L'adaptateur avec R.id.drawables (non inclus dans le code) fonctionne correctement. Le simple fait de placer bitmap dans ImageView fonctionne également. Je pense que le problème est dans mon adaptateur mais je ne sais pas où. Toute aide sera appréciée. Merci.ajouter bitmap à GridView

//gridData.setAdapter(new BitmapAdapter(getBaseContext(), bitmaps));
catButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Ion.with(MainActivity.this)
.load("http://25.media.tumblr.com/tumblr_lpqn543evY1qb1nczo1_500.jpg")//("http://thecatapi.com/api/images/get?format=src")
.progressBar(progressBar)
.progressHandler(new ProgressCallback() {
@Override
public void onProgress(long downloaded, long total) {
downloadCount.setText("" + downloaded + "/" + total);
}
})
.asBitmap()
.setCallback(new FutureCallback<Bitmap>() {
@Override
public void onCompleted(Exception e, Bitmap result) {
if (e != null) {
Toast.makeText(MainActivity.this, "Error downloading file", Toast.LENGTH_LONG).show();
return;
}
//IT WORKS
//ImageView imageView = (ImageView)findViewById(R.id.imageView2);
//imageView.setImageBitmap(result);
bitmaps.add(result);
gridData.setAdapter(new BitmapAdapter(MainActivity.this, bitmaps));
Toast.makeText(MainActivity.this, "File upload complete", Toast.LENGTH_LONG).show();
}
});
}
});
}
}
Et mon adaptateur
public class BitmapAdapter extends BaseAdapter {
private Context mContext;
List<Bitmap> gridViewitems;
public BitmapAdapter(Context c, List<Bitmap> gridViewitems){
mContext = c;
this.gridViewitems=gridViewitems;
}
@Override
public int getCount() {
return 0;
}
@Override
public Object getItem(int position) {
return null;
}
@Override
public long getItemId(int position) {
return 0;
}
// create a new ImageView for each item referenced by the Adapter
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ImageView imageView;
if (convertView == null) {
imageView = new ImageView(mContext);
imageView.setLayoutParams(new GridView.LayoutParams(85, 85));
imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
imageView.setPadding(8, 8, 8, 8);
}
else
{
imageView = (ImageView) convertView;
}
imageView.setImageBitmap(gridViewitems.get(position));
return imageView;
}
}
@EDIT Peut-être que le problème est dans mon dossier de mise en page.

Quel est le problème? – jagapathi
Bitmap ne s'affiche pas dans ma grilleAfficher – PoorGuy
Vous devez configurer votre adaptateur après le chargement de l'image – jagapathi
