How to save Checkboxes on a Recycler View with Shared Preferences

I have a recycler view, inside the row of the recycler view I hava a text with 5 checkboxes. My problem is everytime I check one checkbox the Shared preference save all the checkboxes on that same spot. Here is my code of the adapter

public class HabitosAdapter extends RecyclerView.Adapter<HabitosAdapter.MyViewHolder> {
    private List<Habitos> mHabitosList;
    private Fragment mFragment;
    private Context mContext;
    private CheckBox[] checkBoxes = new CheckBox[5];



    public class MyViewHolder extends RecyclerView.ViewHolder{
        TextView nombre;
        CardView habitosCardView;
        CheckBox CB1, CB2, CB3, CB4, CB5 ;

        public MyViewHolder(View itemView) {
            super(itemView);
            nombre = (TextView) itemView.findViewById(R.id.nombreHabito);
            habitosCardView = itemView.findViewById(R.id.habitos_card_view);
           CB1 = (CheckBox) itemView.findViewById(R.id.CBdia1);
            CB2 = (CheckBox) itemView.findViewById(R.id.CBdia2);
            CB3 = (CheckBox) itemView.findViewById(R.id.CBdia3);
            CB4 = (CheckBox) itemView.findViewById(R.id.CBdia4);
            CB5 = (CheckBox) itemView.findViewById(R.id.CBdia5);
        }
    }

    public HabitosAdapter(Context mContext, List<Habitos> habitosList){
        this.mContext = mContext;
        this.mHabitosList = habitosList;
    }

    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType){
        View itemView = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.habitos_list_row, parent, false);
        SharedPreferences preferences = mContext.getSharedPreferences("PROJECT_NAME", android.content.Context.MODE_PRIVATE);
        boolean valueBoolean = preferences.getBoolean("KEY", false);
        SharedPreferences.Editor editor = preferences.edit();
        editor.putBoolean("KEY", valueBoolean);
        editor.commit();


        return new MyViewHolder(itemView);

    }
      public void onBindViewHolder(@NonNull final MyViewHolder holder, final int position){

        holder.nombre.setText(mHabitosList.get(position).getNombre());

        holder.CB1.setChecked(getFromSP("CB1"));
       holder.CB1.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
                saveInSp("CB1", b);
            }
        });
        holder.CB2.setChecked(getFromSP("CB2"));
        holder.CB2.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View view) {
                if(holder.CB2.isChecked()){
                    saveInSp("CB2", true);
                } else{
                    saveInSp("CB2", false);
                }
            }
        });
        holder.CB3.setChecked(getFromSP("CB3"));
        holder.CB3.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
                saveInSp("CB3", b);
            }
        });
        holder.CB4.setChecked(getFromSP("CB4"));
        holder.CB4.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
                saveInSp("CB4", b);
            }
        });
        holder.CB5.setChecked(getFromSP("CB5"));
        holder.CB5.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
                saveInSp("CB5",b);
            }
        });
     }
    public int getItemCount(){
        return mHabitosList.size();
    }
    private boolean getFromSP(String key) {
        SharedPreferences preferences = mContext.getSharedPreferences("PROJECT_NAME", android.content.Context.MODE_PRIVATE);
        return preferences.getBoolean(key, false);
    }

    private void saveInSp(String key,boolean value){
        SharedPreferences preferences = mContext.getSharedPreferences("PROJECT_NAME", android.content.Context.MODE_PRIVATE);
        SharedPreferences.Editor editor = preferences.edit();
        editor.putBoolean(key, value);
        editor.commit();
    }


}

How can I save just the Checkbox that was checked? I know I have to get just the specific CheckBox that was checked and not set a listener on all the CheckBoxes2 but I dont know how to exactly do that, I am developing my first app, so thanks for your patience.
