私はアンドロイドに不慣れです。sd-cardから画像リストを作成しています。次のコードで「614416バイトの割り当てでメモリが不足しています」というエラーが表示されます。
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater layoutInflater = (LayoutInflater) ctx
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = layoutInflater.inflate(R.layout.ll_sponsor_list_item,
parent, false);
final ImageView img = (ImageView) convertView
.findViewById(R.id.imggrid_item_image);
String imgurl = ImageName.get(position);
AsyncImageLoaderv asyncImageLoaderv = new AsyncImageLoaderv();
Bitmap cachedImage = asyncImageLoaderv.loadDrawable(imgurl,
new AsyncImageLoaderv.ImageCallback() {
public void imageLoaded(Bitmap imageDrawable,
String imageUrl) {
img.setImageBitmap(imageDrawable);
}
});
img.setImageBitmap(cachedImage);
cachedImage.recycle();
return convertView;
}
