将View.GONE设置为View.VISIBLE在获得服务响应之前不起作用，即使View.Gone在发送请求之前也是如此

Question

这是我的mainLayout，点击btnStart我尝试设置scrollView就像去了，然后linearLoading可见。

@Override
public void onClick(View v) {
    switch (v.getId()){
        case R.id.btnGetDni:
            /*some validation*/
            break;
        case R.id.btnGetSign:
            /*some validation*/
            break;

        case R.id.btnStart :
            scrollView.setVisibility(View.GONE);
            linearLayoutLoading.setVisibility(View.VISIBLE);
            startAnim();
            /*some validations*/
            if (something is wrong){
                scrollView.setVisibility(View.VISIBLE);
                linearLayoutLoading.setVisibility(View.GONE);
                stopAnim();
             }else{
                if(something is wrong ){
                    scrollView.setVisibility(View.VISIBLE);
                    linearLayoutLoading.setVisibility(View.GONE);
                    stopAnim();

                }else{
                    if (something is wrong){
                        scrollView.setVisibility(View.VISIBLE);
                        linearLayoutLoading.setVisibility(View.GONE);
                        stopAnim();
                    }else{
                        if (something is wrong){
                           scrollView.setVisibility(View.VISIBLE);
                           linearLayoutLoading.setVisibility(View.GONE);
                           stopAnim();
                            }else{
                            if (something is wrong){
                                scrollView.setVisibility(View.VISIBLE);
                              linearLayoutLoading.setVisibility(View.GONE);
                stopAnim();
                         }else{
                               insert();

                            }
                        }
                    }
                }
            }
        break;
        default :

            break;
    }
}

这是我改变可见性状态的地方。

     private void insert() {
     final LendService lendService = LendRetroFitUtils.getLendService();
     /*collecting*/
     Item item = new Item();
     item.setUserID(idFacebook);
    item.setSignedPaperPhoto(nuevoDNI);
    item.setDniPhoto(newSign);
    item.setCel_brand(brandCellphone);
    item.setCel_model(modelCellphone);
    item.setAndroid_version(versionCellphone);
    .
    .
    .
    /*getting information*/

    List<GpsList> listGpsList = new ArrayList<>();

    lendService.insertUsers(item).enqueue(new Callback<Item>() {
        Gson gson= new Gson() ;
        @Override
        public void onResponse(Call<Item> call, Response<Item> response) {
            Log.i("Response Code", ""+ response.code());

            switch (response.code() ){
                case 404:
                    stopTransition();
                    Toast.makeText(getApplicationContext(),"Usuario incorrecto en Facebook",Toast.LENGTH_LONG).show();
                    break;
                case 403 :
                   stopTransition();
                    Toast.makeText(getApplicationContext(),"El número pin es incorrecto",Toast.LENGTH_LONG).show();
                    break;
                case 418 :
                    stopTransition();

                    Intent openBrowser = new Intent(Intent.ACTION_VIEW, Uri.parse("/*url*/"));
                    startActivity(openBrowser);
                    break;
                case 422:
                    stopTransition();
                    String errorBodyRaw = null;
                    try {
                        errorBodyRaw = response.errorBody().string();
                    } catch (IOException e) {
                        e.printStackTrace();
                    }
                    String body = errorBodyRaw.substring(0,errorBodyRaw.length());
                    Log.i(" LOG ::::::", "body"+body+"n");
                    JsonObject jsonObjectParsed=  new JsonParser().parse(errorBodyRaw).getAsJsonObject();

                    ResponseErrorItem obj= gson.fromJson(jsonObjectParsed,ResponseErrorItem.class);

                    if (obj.getStatus() != null){
                        /*some validations on error*/
                    }
                    break;
                case 500:
                    stopTransition();
                    Toast.makeText(getApplicationContext(),"error message",Toast.LENGTH_LONG).show();
                    break;
                default :
                    stopTransition();
                    Toast.makeText(getApplicationContext(),"error message",Toast.LENGTH_LONG).show();

            }
        }

        @Override
        public void onFailure(Call<Item> call, Throwable t) {
            Log.i("onFailure",""+call);
            Log.i("onFailure",""+t);
           stopTransition();
            Log.e("Main Activity", "Unable to submit post to API.");
            if (call.isCanceled()){
                Log.e("Main Activity", "request was aborted");
            }else {
                Log.e("Main Activity", "Unable to submit post to API.");
            }
        }
    });
}

在插入内部（）我正在进行改造请求。主要问题是动画从服务获得响应后启动。  这是方法insert（）

 void startAnim(){
    avi.show();
    // or avi.smoothToShow();
}

void stopAnim(){
    avi.hide();
    // or avi.smoothToHide();
} 

startAnim（）和stopAnim（）
