RecyclerView不会在Android 5.1.1上更新UI [英] RecyclerView doesn't update UI on Android 5.1.1

问题描述

我有一个问题，仅在Android 5.1.1和5.1上的设备很少.在其余版本上都可以正常工作.

I have a issue that reprodusing only on Android 5.1.1 and few devices on 5.1. On the rest of versions works fine.

Recycler视图具有onClick侦听器，我尝试将View Visibility从GONE更新为VISIBLE或相反.单击项目后，UI上没有任何更改. 注意:如果我关闭(BackButton)片段并再次打开-UI将被更新.即使按下后退按钮，我仍然看到UI在销毁前会更新几毫秒.

Recycler view have onClick listener whereI try to update View Visibility from GONE to VISIBLE or conversely. After clicking on item nothing changes on UI. Note: If I close (BackButton) Fragment and open once again - UI will be updated. Even after pressing back button I see that UI updating for few milliseconds before destroing.

我试图通知所有适配器，当前项，使itemView无效，swap()并再次设置适配器，但均未成功. 所有方法setVisibility()，onClick，Callbacks，BindView均已成功调用(调试器).

I tryed to notify all adapter, current item, invalidate itemView, swap() and set adapter again without success. All methods setVisibility(), onClick, Callbacks, BindView are successfully called (debugger).

public class PhotoGalleryAdapter extends RecyclerView.Adapter<PhotoGalleryAdapter.PhotoHolder> {

    private Context context;
    private List<String> photos;
    private View.OnClickListener listener;

    public PhotoGalleryAdapter(Context context, List<String> photos, View.OnClickListener listener) {
        this.context = context;
        this.photos = photos;
        this.listener = listener;
    }

    @Override
    public PhotoGalleryAdapter.PhotoHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_photo, parent, false);
        return new PhotoHolder(v, listener);
    }

    @Override
    public void onBindViewHolder(final PhotoGalleryAdapter.PhotoHolder holder, int position) {
        String photoPath = photos.get(position);
        Glide.with(context)
                .load(photoPath)
                .thumbnail(0.1f)
                .into(holder.image);

        if (Utils.getSelectedPhotos().contains(photoPath)) {
            DrawableCompat.setTint(holder.selection.getDrawable(), ContextCompat.getColor(context, R.color.white));
            holder.selection.setVisibility(View.VISIBLE);
        } else {
            holder.selection.setVisibility(View.GONE);
        }
    }

    @Override
    public int getItemCount() {
        return photos.size();
    }

    public void updateDataSet(List<String> photos) {
        if (!photos.equals(this.photos)) {
            this.photos.clear();
            this.photos.addAll(photos);
            notifyDataSetChanged();
        }
    }

    class PhotoHolder extends RecyclerView.ViewHolder implements View.OnClickListener {

        @BindView(R.id.imageView) AppCompatImageView image;
        @BindView(R.id.selectionState) AppCompatImageView selection;

        private View.OnClickListener listener;

        PhotoHolder(View view, View.OnClickListener listener) {
            super(view);
            ButterKnife.bind(this, view);
            view.setOnClickListener(this);
            this.listener = listener;
        }

        @Override
        public void onClick(View view) {
           if (Utils.getSelectedPhotos().contains(photos.get(getAdapterPosition()))) {
                selection.setVisibility(View.GONE);
                Utils.getSelectedPhotos().remove(photos.get(getAdapterPosition()));
            } else {
                Utils.getSelectedPhotos().add(photos.get(getAdapterPosition()));
                DrawableCompat.setTint(selection.getDrawable(), ContextCompat.getColor(context, R.color.white));
                selection.setVisibility(View.VISIBLE);
            }
            listener.onClick(view);
        }
    }
}

然后回调:

 @Override public void onClick(View view) {
     callbacks.onPhotoSelected(Utils.getSelectedPhotos().size());
     adapter.notifyDataSetChanged(); }

推荐答案

更新解决方案:将onClick更改为:

Update Solution: after changing onClick to:

     @Override
            public void onClick(View view) {
               if (Utils.getSelectedPhotos().contains(photos.get(getAdapterPosition()))) {
                    Utils.getSelectedPhotos().remove(photos.get(getAdapterPosition()));
                } else {
                    Utils.getSelectedPhotos().add(photos.get(getAdapterPosition()));
                }
                notifyDataSetChanged();
                listener.onClick(view);
            }

效果很好，但是仅适用于LinearLayoutManager.仍然不适用于GridLayoutManager. 因此，在两次调用setVisibility()之后，Android无法正常工作.

Works good, BUT only with LinearLayoutManager. Still doesn't works with GridLayoutManager. So after calling setVisibility() twice Android works unpredictably.
