如何传递数组列表<Object>到另一个活动

问题描述

我将数组列表传递给意图，但出现错误.所以请告诉我出了什么问题.这是我的代码

I pass Array list to intent but give an error . so please tell me what is wrong.This is my code

用于发送

addToCartList=new ArrayList<>();
Intent intent=new Intent(ShopingCart.this,SelectedProductFromShopingCartShow.class);
intent.putExtra("selectedList", (Serializable) addToCartList);
startActivity(intent);

这是我的接收器代码

public class SelectedProductFromShopingCartShow extends AppCompatActivity{

    ArrayList<ShowProducts> arrayList=new ArrayList<>();
    String condition="SelectedItemsFromShoppingCart";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_selected_product_from_shoping_cart_show);

        arrayList= (ArrayList<ShowProducts>) getIntent().getSerializableExtra("selectedList");

    }
}

这是我的错误

推荐答案

请在您的模型类中编写ShowProducts implements Serializable.
这将解决问题.

Please write ShowProducts implements Serializable in your model class.
This will resolve the issue.
