is there any way to remove this error during scroll ,so please help me .

[byvlstr]

I asked "applm", here is his reply :

View from adapter gets into viewcache without being wrapped int CoverFrame. Every view should be wrapped in coverFrame. I dont know how it can happen that one is not.
You can try debugging it. Or just add check with instanceof before cast and cast it only when correct class is supplied by cache.

I tried to put an "instanceof" before the cast, but the error still occurs. Don't get how this is possible...
Any ideas on how to fix this issue?

I was able to fix this issue doing the following

protected View getViewFromAdapter(int position){
    CoverFrame finalFrame;
    View currView = mCache.getCachedView();
    if (currView instanceof CoverFrame) {
        finalFrame = (CoverFrame)currView;
        View recycled = finalFrame.getChildAt(0);

        View v = mAdapter.getView(position, recycled, this);

        finalFrame.setCover(v);
    }
    else {
        View v = mAdapter.getView(position, null, this);

        finalFrame = new CoverFrame(getContext(), v);
    }

    //to enable drawing cache
    if(android.os.Build.VERSION.SDK_INT >= 11) finalFrame.setLayerType(LAYER_TYPE_SOFTWARE, null);
    finalFrame.setDrawingCacheEnabled(true);

    return finalFrame;
}

I will be forking this repo to improve upon it, thanks for the great library.
