Android: How to pass Parcelable object to intent and use getParcelable method of bundle?

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?

Solution

  • 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");
