使用 Parceable 将数据从活动传递到片段时获取空值

Question

I am trying to pass arraylist from activity to fragments but i am getting a null value using the parceable.

In Main Activity:

Bundle bundle = new Bundle();
                    bundle.putParcelableArrayList("cbookings", customerbooking);
                    Todaybooking tb = new Todaybooking();
                    tb.setArguments(bundle);

Array list data declarations

ArrayList<Cbooking> customerbooking = new ArrayList<>();

In fragments:

ArrayList<Cbooking> customerbooking = new ArrayList<>();

    Bundle extras = getActivity().getIntent().getExtras();
    customerbooking = extras.getParcelableArrayList("cbookings");
    Log.wtf("test", customerbooking.toString());

Answer 1

You are using setArguments() to pass the data into the fragment. Therefore, you need to use getArguments() to retrieve the data, not getActivity().getIntent().getExtras() .
