android.widget.FrameLayout$LayoutParams cannot be cast to android.widget.AbsListView$LayoutParams


There are other related issues on this but they do not address my situation (their error code has to do with some sort of recycling and/or bad cast calls by client code).

My situation is more complex.

I have some code where the user can pull up a library of photos.

The thing is, its working just fine on 7 phones that I have, all running API's 19+.

However I have a Google Nexus 4.3 that's running API 17. And I get this crash log which has none of my code, only library code. If you can advise how I might be able to code a work around I'd be all ears:

Update

My offending class is this:

 //Special class that works with the UIL
    //The holder gets re-used and gets the new properties from this
    static class ReusableGridViewView extends FrameLayout
    {
        public ImageView imageView;
        public ProgressBar progressBar;

        public ReusableGridViewView(Context context)
        {
            super(context);

            setLayoutParams(new LayoutParams((int)(0.325* ViewHelper.screenWidthPX(context)),(int)(0.325* ViewHelper.screenWidthPX(context))));

            imageView = new ImageView(context);
            progressBar = new ProgressBar(context);

            addView(imageView);
            addView(progressBar);
        }
}

Im using the Ultimate Image Loader library and this is the code that uses the above class.

 //I do NOT call this directly, the listview decides when re use a convert view and passes it accordingly
        @Override
        public View getView(int position, View convertView, ViewGroup parent)
        {
            final ViewHolder holder;
            View view = convertView;
            if (view == null)
            {
                view = new ReusableGridViewView(parent.getContext());

                holder = new ViewHolder();
                assert view != null;
                holder.imageView = ((ReusableGridViewView)view).imageView;
                holder.progressBar = ((ReusableGridViewView)view).progressBar;
                holder.imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
                view.setTag(holder);
            } else {
                holder = (ViewHolder) view.getTag();
            }

            //System.out.println(" " + holder + " ||| " + holder.imageView);
            ImageLoader.getInstance()
                    .displayImage(IMAGE_URLS[position], holder.imageView, options, new SimpleImageLoadingListener()
                    {
                        @Override
                        public void onLoadingStarted(String imageUri, View view)
                        {
                            holder.progressBar.setProgress(0);
                            holder.progressBar.setVisibility(View.VISIBLE);
                        }

                        @Override
                        public void onLoadingFailed(String imageUri, View view, FailReason failReason)
                        {
                            holder.progressBar.setVisibility(View.GONE);
                        }

                        @Override
                        public void onLoadingComplete(String imageUri, View view, Bitmap loadedImage)
                        {
                            holder.progressBar.setVisibility(View.GONE);
                        }

                    }, new ImageLoadingProgressListener()
                    {
                        @Override
                        public void onProgressUpdate(String imageUri, View view, int current, int total)
                        {
                            holder.progressBar.setProgress(Math.round(100.0f * current / total));
                        }
                    });

            //set all as unselected
            ((ReusableGridViewView) view).removeSelectionBorder();
            for(int i = 0; i < SELECTED_IMAGES.length; i++)
            {
                if(SELECTED_IMAGES[i] == position)
                {
                    //set cell to selected
                    ((ReusableGridViewView) view).addSelectionBorder();
                }
            }
            return view;
        }

Solution

  • So it turns out that on API < 17 FrameLayout can't be cast correctly to AbsListView params.

    What I did was set AbsListView LayoutParams instead of FrameLayout params:

        setLayoutParams(new AbsListView.LayoutParams(100,100));
