display json string data to spinners

Question

in this case I want to display the json string data to the spinner, but the form of the data is not just a list but just a string. How can I display the string data to the spinner.

private void getmemberDetail(){ ///// loading = ProgressDialog.show(mContext, null, "Harap Tunggu...", true, false);

mApiService.getMemberDetail().enqueue(new Callback<ResponseMembers>() {
        @Override
        public void onResponse(Call<ResponseMembers> call, Response<ResponseMembers> response) {
            if(response.body() !=null){
                ResponseMembers responseMembers = response.body();
                List<ResultItem> details = responseMembers.getResult();
                for(ResultItem d : details){
                    if(d.getId().equals(sharedPrefManager.getSpIdMember())){
                        reqresultItem = d;

                        runOnUiThread(new Runnable() {

Answer 1

Check My below code

ArrayList<String> genderList=new ArrayList<>();
genderList.add(reqresultItem.getMetadata().getGenders());
ArrayAdapter<String> genderAdapter= new ArrayAdapter<String>(MyActivityClass.this,android.R.layout.simple_spinner_item, genderList);
genderAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
genderSpinner.setAdapter(gameKindArray); 

Answer 2

Use ArrayAdapter this way

your should create an array from server's data for example

   String[] testData=new String[]{data.gender};

your ArrayAdapter

   ArrayAdapter<String> genderAdapter= new ArrayAdapter<String>(MyActivityClass.this,android.R.layout.simple_spinner_item, test);
   genderAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
   genderSpinner.setAdapter(gameKindArray);
