我的应用程序中有 FB、Google 和正常登录。当我使用 FB 或 google 登录时，一切都很好，但是每当我从应用程序注册并立即登录时，我没有在 CartActivity RecyclerView 中获取数据，但数据显示在邮递员中或浏览器。当我卸载应用程序并重新安装数据时，再次开始显示旧的登录凭据。购物车活动：

    try {
        StringRequest stringRequest = new StringRequest(Request.Method.GET, url2,
                new Response.Listener<String>() {
                    @Override
                    public void onResponse(String response) {
                        pd.dismiss();
                        // Toast.makeText(CartActivity.this, "responce"+response.toString(), Toast.LENGTH_SHORT).show();
                        System.out.println("Response is : " + response);
                        try {
                            JSONObject jsono = new JSONObject(response);
                            if (jsono.getString("status").equals("success")) {
                                JSONArray jarray = jsono.getJSONArray("data");
                                for (int i = 0; i < jarray.length(); i++) {

如果您获得如下代码的响应时间，请创建一个定义所有字段的 pojo 类。

public class DataClass {
String Name ;
String Image ;
String Price ;
String Qty ;
String sku ;
String ProId;

public String getName() {
    return Name;
}

public void setName(String name) {
    Name = name;
}

public String getImage() {
    return Image;
}

public void setImage(String image) {
    Image = image;
}

public String getPrice() {
    return Price;
}

public void setPrice(String price) {
    Price = price;
}

public String getQty() {
    return Qty;
}

public void setQty(String qty) {
    Qty = qty;
}

public String getSku() {
    return sku;
}

public void setSku(String sku) {
    this.sku = sku;
}

public String getProId() {
    return ProId;
}

public void setProId(String proId) {
    ProId = proId;
}

}

在回收器视图适配器中添加列表，如 ....

 private List<DataClass> mDataList=new ArrayList<>();

public CustomAdapter(List<DataClass> mDataList) {
    this.mDataList = mDataList;
}

然后在获取响应数据后添加到数组列表并传递到适配器..

private List<DataClass> mListData=new ArrayList<>();// define in type-array in your pojo class name
  for (int k = 0; k < jarray2.length(); k++) {
        JSONObject object2 = jarray2.getJSONObject(k);
        DataClass dataClass=new DataClass();
        String Name = object2.getString("product_name");
        String Image = object2.getString("product_image");
        String Price = object2.getString("product_price");
        String Qty = object2.getString("product_qty");
        String sku = object2.getString("product_sku");
        String ProId = object2.getString("product_id");
        dataClass.setName(Name);
        dataClass.setImage(Image);
        dataClass.setPrice(Price);
        dataClass.setQty(Qty);
        dataClass.setSku(sku);
        dataClass.setProId(ProId);
        mListData.add(dataClass);
        System.out.println("VALUES: " + Name + "price" + Price + "qty" + Qty + sku + "proid" + ProId);
    }
    if (!mListData.isEmpty()){
        cartAdapter=new CartAdapter(mListData);
        rccart.setAdapter(cartAdapter);
        cartAdapter.notifyDataSetChanged();
    }

得到了解决方案。这是因为缓存而发生的。刚刚清除缓存并解决问题。
