如何将自定义对象arraylist从活动传递到带有实例的片段 [英] How to pass custom object arraylist from activity to fragment with instance

问题描述

我正在使用viewpager并创建片段，我想传递arraylist.因此，我尝试了以下操作:

I am using viewpager and creating fragments and i want to pass the arraylist. So i have tried the below things:

MainActivity:

MainActivity:

 private ArrayList<customers> mArrayList = null;

  ViewPagerAdapter adapter = new ViewPagerAdapter(MainActivity.this.getSupportFragmentManager());

  adapter.addFrag(NewCustomer.newInstance(mArrayList ), "NewCustomer");

现在在片段类中，我正在创建实例:

Now in fragment class i am creating instance:

 public static final ArrayList<customers> data = new ArrayList<customers>();

 public static final NewCustomer newInstance(ArrayList<customers> mArrayList) {

        NewCustomer f = new NewCustomer();
        Bundle bdl = new Bundle(1);
        bdl.putParcelableArrayList(data, mArrayList);
        f.setArguments(bdl);
        return f;
    }

但是这不起作用.我要获取arraylist并将其存储到该类的本地arraylist上的bdl.putParcelableArrayList上显示错误.

But this is not working. It is showing error on bdl.putParcelableArrayList I want to get arraylist and store into the local arraylist of that class.

如何获取带有自定义对象的arraylist?

How can i get the arraylist with my custom object ?

推荐答案

可以尝试吗?

public static final NewCustomer newInstance(ArrayList<customers> mArrayList) {

        NewCustomer f = new NewCustomer();
        Bundle bdl = new Bundle(1);
        this.data = mArrayList; // assign its Value
        bdl.putParcelableArrayList(data, mArrayList);
        f.setArguments(bdl);
        return f;
    }

this.data = mArrayList 将为片段的当前成员变量赋值.现在我们可以在当前片段中对其进行访问了.

this.data = mArrayList will assign value to the current member variable of fragment. Now it can we be accessed in current fragment.
