两个Activity传递List数据

1. List<T>的Bean对象，Bean类实现Serializable接口,(如果包含其他bean类也需要实现)

public class DogBo implements Serializable {
    
}

2. Activity跳转传递参数

List<DogBo > dogList = new ArrayList<>();
Intent intent = new Intent(this, OneActivity.class);
intent.putExtra("dog", (Serializable) dogList );
startActivity(intent);

3. 目标Activity接受数据

Intent intent = getIntent();
List<DogBo > dogList = (List<DogBo>) intent.getSerializableExtra("dog");
