Android BucketListAdapter

This is an implementation of the bucket list adapter, similar to what you see in the Google Play app. It has a grid layout of list items, with the advantage that you can still use the list of headers and footers - something that is not possible with the standard GridView.

You can use this. Use OnScrollListener to control the scroll position; when scrolling to the last item, you can control the visibility of the load view.

        @Override
    public void onScroll(AbsListView view, int firstVisibleItem,
            int visibleItemCount, int totalItemCount) {
        if (mOnScrollListener != null) {
            mOnScrollListener.onScroll(view, firstVisibleItem,
                    visibleItemCount, totalItemCount);
        }
        // The count of footer view will be add to visibleItemCount also are
        // added to totalItemCount
        if (visibleItemCount == totalItemCount) {
            // If all the item can not fill screen, we should make the
            // footer view invisible.
        } else if (!mIsLoading
                && (firstVisibleItem + visibleItemCount >= totalItemCount)
                && mCurrentScrollState != SCROLL_STATE_IDLE) {
            mIsLoading = true;
            if (mOnLoadMoreListener != null) {
                mOnLoadMoreListener.onLoadMore();
            }
        }
    }
