android-gridview

I have a GridView in android which I fill it with data retrieved from a xml resource. For example I have 15 items in the GridView which are placed in order. The overall height exceeds the Screen height so i have to scroll to see the rest of the items. The problem is when I scroll back up, the order of the invisible rows have changed. It's a mysterious behavior as sometimes items swap rows with each other. Here is my getView method: public class ImageAdapter extends BaseAdapter { public ImageAdapter(Context c, NodeList cuu) { cu = cuu; } public int getCount() { Log.d("Node Count",cu.getLength()

I have a GridView for showing some icons. BEFORE I had read this Displaying Bitmaps Efficiently from Android developer site, I was decoding bitmap from local path directly in getView() of adapter, like this : public View getView(int position, View convertView, ViewGroup parent) { ... ImageView icon = ...... (from getTag() of convertView) icon.setImageBitmap(BitmapUtil.decode(iconPath)); ... } this way works fine anyway, I called it [Direct Mode], the output log for getView() method should be : getView(0) // measure kid's layout. getView(0) getView(1) getView(2) ... getView(n) // when scrolling

This thing has been doing my head in for a little while now and I can't seem to be able to solve it. I've got a grid view, in which I display a few bitmaps. I add a padding of 5dp on all image sides when filling up my image view via the adapter (iv.setPadding(5, 5, 5, 5);), but somehow, there's more space being added to the top and bottom on each item on my gridview. I know this has already been asked a few times here , and some of them even have accepted answers, however, when I try to sue the answers as described on the URL's above, I still keep getting the same extra spaces on top and
