java.lang.IllegalStateException: Cannot call this method while RecyclerView is computing a layout or scrolling when notifydatasetChanged()

Question

For calling API after creating the activity, I need to perform click event for RecyclerView item of " 0 " index.

for that in onBindviewHolder I'm calling holder.view.performClick event. But the Problem is I need to call a notifydataSetChanged() method in onClick event to update the adapter. Initially, it will auto click on position "0" and calling notifydataSetChanged() method and crashing. What is the solution for this problem? kindly help.

public void onBindViewHolder(ViewHolder holder, int position) {
    if (position==0){
        holder.itemView.performClick();
    }

I'm calling this interface in MainActivity.class

public void onRecyclerViewItemClick(@NonNull View view, @NonNull CalendarDTO calendarDTO, int position) {
    isClickedPosition=position;
    adapter.notifyDataSetChanged();
    Toast.makeText(this, calendarDTO.getDate(), Toast.LENGTH_SHORT).show();
}

please check the error:-

Answer 1

Try This

In OnBindViewHolder

public static  boolean isPerformClicked;
int performClickCount;

 @Override
public void onBindViewHolder(ViewHolder viewHolder, int i) {
    if (i==0){
        viewHolder.tv_android.setBackgroundColor(Color.RED);
        if (performClickCount==0){
            isPerformClicked = true;
            viewHolder.itemView.performClick();
        }else{
            viewHolder.tv_android.setBackgroundColor(Color.RED);
        }

    }else{
        isPerformClicked=false;
        performClickCount = performClickCount+1;
        viewHolder.tv_android.setBackgroundColor(Color.YELLOW);

    }
    if (i!=BlankFragment.selectedPosition){
        viewHolder.tv_android.setBackgroundColor(Color.YELLOW);
    }else{
        viewHolder.tv_android.setBackgroundColor(Color.RED);
    }

    viewHolder.tv_android.setText(android_versions.get(i).getAndroid_version_name());
    Picasso.with(context).load(android_versions.get(i).getAndroid_image_url()).resize(120, 60).into(viewHolder.img_android);
}

In holder Item Click or item

  @Override
public void onRecyclerViewItemClick(@NonNull View view, @NonNull AndroidVersion calendarDTO, int position) {
    selectedPosition=position;
    Toast.makeText(getContext(),String.valueOf(position), Toast.LENGTH_SHORT).show();
    if (!isPerformClicked){
        adapter.notifyDataSetChanged();
    }
}
