问题描述

我正在尝试从recyclerview中删除我的商品,但是我总是遇到错误

I am Trying to remove my item from recyclerview, but i always getting error

我正在使用通知数据集已更改,我能解决这个问题吗?

i am using notify datasetchanged, can i solve this?

public class AdapterIntransit extends RecyclerView.Adapter<AdapterIntransit.ViewHolder> {
    private Context context;
    List<DataIntransit> data;

    public AdapterIntransit(Context context, List<DataIntransit> data) {
        this.context = context;
        this.data = data;
    }

    @Override
    public AdapterIntransit.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.cardintransit, parent, false);
        return new ViewHolder(itemView);
    }

    @Override
    public void onBindViewHolder(AdapterIntransit.ViewHolder holder, int position) {
        if (data.get(position).getJml1() - data.get(position).getJml2() <= 0) {
            data.remove(position);
            notifyItemRemoved(position);
            notifyItemRangeChanged(position, getItemCount());
            notifyDataSetChanged();
        } else {
            holder.kode.setText(data.get(position).getKode());
            holder.nama.setText(data.get(position).getNama());
            holder.jumlah.setText(String.valueOf(data.get(position).getJml1() - data.get(position).getJml2()));
        }
    }

    @Override
    public int getItemCount() {
        return data.size();
    }
    public class ViewHolder extends RecyclerView.ViewHolder{
        TextView kode, nama, jumlah;
        public ViewHolder(View itemView) {
            super(itemView);
            kode = (TextView)itemView.findViewById(R.id.kode);
            nama = (TextView)itemView.findViewById(R.id.nama);
            jumlah = (TextView)itemView.findViewById(R.id.jumlah);

        }
    }
}

推荐答案

以下答案对我有用

Below answer worked for me

这只是问题的workaround.

通常在您在background thread上调用notifyDataSetChanged()时发生.因此,只需将通知移至UI thread

This usually occurs when you are calling notifyDataSetChanged() on the background thread. So just move notify to UI thread

dialeecyclerView.post(new Runnable()
            {
                @Override
                public void run() {
                myadapter.notifyDataSetChanged();
            }
            });

更多信息,如果需要,您可以在UI线程上运行它

For more you can run it on UI thread, if you needed

 runOnUiThread(new Runnable(){
 public void run() {
      // UI code goes here
 }
 });
