Scroll is slower than Android's GridView

[HomHomLin]

I have used StickyGridHeadersGridView instead of gridview. In gridview , everything scroll smooth and fast, but in StickyGridHeadersGridView, it's not very slow but it's not smooth and fast as gridview does. It's just a bit slower.

I don't know why, I have my code in getView & getHeaderView like this:

@Override
public View getHeaderView(int position, View convertView, ViewGroup parent) {
    if(convertView == null){
        GridViewHeader item = GridViewHeader_.build(mActivity);
        convertView = item;
    }
    GridViewHeader item = (GridViewHeader)convertView;
    item.init(getItem(position).time);
    return convertView;
}

I agree. I am having performance issues as well

I noticed this as well. I deleted the StickyGridHeadersGridView#onTouchEvent(MotionEvent ev) function and my scrolling became buttery smooth. I also didn't notice any loss of functionality but I'm not using the more advanced feature like long clicks or header click listeners.

My Picasso-powered grid items now stay blank for seconds before starting to load its images.

I use Picasso as well. Really looking for a stable solution using Picasso and sticky grid headers

I'm getting the feeling that item views are not being recycled properly, as the performance drops in direct proportion to the number of items, and items near the bottom have to wait por its images to be loaded far longer than the top ones.
