Why bundle has getParcelableArrayList
, getParcelable
methods; but
Intent
has only putParcelableArrayListExtra
method?
Can I transmit only object<T>
, not ArrayList
of one element?
Then, what is getParcelable
for?

Intent provides bunch of overloading putExtra() methods.
Suppose you have a class Foo implements Parcelable properly, to put it into Intent in an Activity:
Intent intent = new Intent(getBaseContext(), NextActivity.class);
Foo foo = new Foo();
intent.putExtra("foo ", foo);
startActivity(intent);
To get it from intent in another activity:
Foo foo = getIntent().getExtras().getParcelable("foo");

Sender Activity:
val intent = Intent(this, RestaurantDetails::class.java)
intent.putExtra(Constants.RESTAURANT, restaurant)
startActivity(intent)
Receiver Activity:
val restaurant = intent.getParcelableExtra<Restaurant>(Constants.RESTAURANT)

It is important to remember that your models must implement the Parcelable interface, and the static CREATOR method. This case is for the lists
private static final String MODEL_LIST = "MODEL_LIST";
public MainFragment() {}
public static MainFragment newInstance(ArrayList<YourModel>
models) {
MainFragment fragment = new MainFragment();
Bundle args = new Bundle();
args.putParcelableArrayList(MODEL_LIST,models);
fragment.setArguments(args);
return fragment;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (getArguments() != null) {
ArrayList<YourModel> models = getArguments().getParcelableArrayList(MODEL_LIST);
}
}

First create Parcelable using Given Technique then
public static CreditCardDetail newInstance(CreditCardItemBO creditCardItem) {
CreditCardDetail fragment = new CreditCardDetail();
Bundle args = new Bundle();
args.putParcelable(CREDIT_KEY,creditCardItem);
fragment.setArguments(args);
return fragment;
}
And getting it like
if(getArguments() != null)
{
creditCardItem = getArguments().getParcelable(CREDIT_KEY);
}
where
public static final String CREDIT_KEY = "creditKey";
