- cache the images to disk
- use a List<String> to store the paths to the cached images
- extend a BaseAdapter and use the List<String> as your data source
- add a setPage(int page) method to set which page of 10 images you're
on
- in getView() adjust the value of position to account for the page
index
quick example from memory:
public class PagedPhotoAdapter extends BaseAdapter {
private static final int PHOTOS_PER_PAGE = 10;
private final LayoutInflater mInflater;
private final List<String> mPhotoPaths;
private final int mPageCount;
private int mPage = 0;
public PagedPhotoAdapter(Context context, List<String> photoPaths) {
mInflater = LayoutInflater.fromContext(context);
mPhotoPaths = photoPaths;
mPageCount = (mPageCount.size()/PHOTOS_PER_PAGE);
}
public void setPage(int page) {
mPage = page < 0 ? 0 : page > mPageCount ? mPageCount : page;
}
@Override public int getCount() {
return PHOTOS_PER_PAGE;
}
@Override public Object getItem(int position) {
return position;
}
@Override public int getItemId(int position) {
return position;
}
@Override public View getView(int position, View convertView,
ViewGroup parent) {
final int adjPosition = ((PHOTOS_PER_PAGE * mPage)+position)-1;
final ImageView imageView =
(ImageView)(convertView==null?mInflater.inflate
(R.layout.layout_id, null):convertView);
imageView.setImageBitmap(BitmapFactory.decodeFile(mPhotoPaths.get
(adjPosition)));
return imageView;
}
}
