How to clear highlighted items in the recyclerview?

Question

I have implemented the recycler view multiple item selection by changing the background color of item when selected.When i remove those items from the model, items get remov

Answer 1

Your problem is in when (holder.is_selected.isChecked) {

You should have the information if an item is checked on the ViewModel, not on the View and most definitely not in the ViewHolder.

It should be something like if(residentItems.get(posistion).isSelected){ (Using when is overkill for binary cases)

Answer 2

Try this:

Take a Boolean variable in your POJO class

public class POJO {

    boolean isSelected;

    public boolean isSelected() {
        return isSelected;
    }

    public void setSelected(boolean selected) {
        isSelected = selected;
    }
}

make below change in your onBindViewHolder() method

 @Override
public void onBindViewHolder(@NonNull RecyclerView.ViewHolder holder, int position) {

    if(pojoArrayList.get(position).isSelected()){
        // make selection in your item
    }else {
        //remove selction from you item
    }
}

Now inside your onLongClickListener make your selection true

sample code

    sampleButton.setOnLongClickListener(new View.OnLongClickListener() {
        @Override
        public boolean onLongClick(View view) {

            // set the status of selection 
            pojoArrayList.get(position).setSelected(true);

            return true;
        }
    });

And when your want to remove selection use this

  pojoArrayList.get(position).setSelected(false);

and when you want to delete item from list use that boolean variable to delete item

 if(pojoArrayList.get(position).isSelected()){
        //remove the item from list
       // and  notifyDataSetChanged(); after removing the item from list
 }
