我已經寫了一類，這是擴大BaseAdapter類和代碼列表如下：\BaseAdapter類
public class ImageAdapter extends BaseAdapter {
int mGalleryItemBackground;
private Context mContext;
public ArrayList<Drawable> drawablesFromUrl = new ArrayList<Drawable>();
public ImageAdapter(Context c) {
mContext = c;
}
public void addItem(Drawable item) {
drawablesFromUrl.add(item);
}
public int getCount() {
return drawablesFromUrl.size();
}
public Drawable getItem(int position) {
return drawablesFromUrl.get(position);
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) { // if it's not recycled, initialize some attributes
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.setImageDrawable(drawablesFromUrl.get(position));
return imageView;
}//View getView
}//class ImageAdapter
現在我想使用對象「drawablesFromUrl.get（位置）」進另一個活動和解決方案之一是在「應用程序類」中編寫此類，以便我可以在應用程序的任何位置使用該對象。但不知道如何實施？或者有沒有其他解決方案可以解決我的問題？
謝謝！
