如何通过单选按钮在Recycler View中调用API

Question

today I try to call api to display recycleView with the help of 2(male-female) RadioButton .

Here 2 RadioButton and behind "choose your gender" recycleView hide

After api call my recycleView Item shown this

"what happing in api:- (i) I have some item(locker) list, which is shown as image

(ii) after api call i have information of some locker(item) which is locked.

(iii) I want show locked locker with some diff color and unlocked locker with some diff. color. (Currently all are in same color, after api call also)

(iv)Now I want to just check my code and let me understand where am I wrong.

(v) I am new in android and want to realize my fault.

 //this is male button code(same female)
    rgGender.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(RadioGroup group, int checkedId) {

            selectedId = rgGender.getCheckedRadioButtonId();
            switch (selectedId) {
                case R.id.rb_male: {
                    booleanLockerList = new ArrayList<>();
                    lockerModels = new ArrayList<LockerModel>();
                    BooleanModelClass booleanLocker = new BooleanModelClass();

                    for (int i = 0; i < malelockerNumber.size(); i++) {
                        booleanLocker.setId("");
                        booleanLocker.setCardid("");
                        booleanLocker.setCby("");

                            {

                                count++;
                            }
                        }

                    setAdapterLocation();
                    break;
                }

(vi) now this is my adapter class-

 public void onBindViewHolder(final TempAdapter.ViewHolder holder, final int position) {


    holder.myTextView.setText(lockerNumber.get(position));
    Boolean first1=booleanLockerList.get(position).getKey();
    if((first1))
    {
        holder.click.setBackgroundColor(context.getResources().getColor(R.color.blue));

    }
    else
    {
        holder.click.setBackground(context.getResources().getDrawable(R.drawable.border));
    }

(vii) Here(currently) first adapter run and then api hit. I din't recognize the error(not error) but not exact working.

如果要在获取数据后重新绑定适配器，则需要将新数据传递给适配器，然后调用notifyDataSetChanged（）;。
