这个错误让我发疯

这是传递参数的代码：

Intent intent = new Intent(this, TheClass.class);
Bundle bundle = new Bundle();
bundle.putInt("int_value",1);
bundle.putParcelableArrayList("USER_ARR",arr);
intent.putExtras(bundle);
startActivity(intent);

arr 是 ArrayList 并且 User 是 parcellable

另一边是：

Bundle bundle = this.getIntent().getExtras();
ArrayList<User> users = bundle.getParcelableArrayList("USER_ARR");
int int_value = bundle.getInt("int_value");

我也尝试关注这个链接：Problems passing integer and serializable on bundle and do it without bundles, but still can't get it to work the integer is not pass, unless it is passed without the paracellable array list

编辑：

用户类如下所示：

    this.setUserId(user_id);
}


public int getUserId() {
    return user_id;
}

    this.user_id = user_id;
}

public String getName() {
    return name;
}

发现发生了什么，这与我问的一个较新的问题有关，该问题也没有任何答案

问题是：parcelable ArrayList 部分传递了空元素

只有当字节数组的大小大于零时，我才在我的 parcelable 中读取字节数组，但不读取它并没有推进 dataPosition()

感谢这个问题Make custom Parcelable contains byte array我找到了答案

祝大家有美好的一天
