为什么要捆绑有getParcelableArrayList，getParcelable方法，但 目的只有方法putParcelableArrayListExtra？ 我可以只发送对象＆LT; T>，而不是一个元素的ArrayList的？ 对于什么呢getParcelable？

Why bundle has getParcelableArrayList, getParcelable methods, but intent has only method putParcelableArrayListExtra ? Can I transmit only object < T > , not ArrayList of one element ? For what then getParcelable ?

推荐答案

意图提供了一堆超载putExtra()的方法。

Intent provides bunch of overloading putExtra() methods.

假设你有一个类Foo实现Parcelable得当，把它变成意图的活动：

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);

要得到它的意图在另一项活动：

To get it from intent in another activity:

Foo foo = getIntent().getExtras().getParcelable("foo");

希望这有助于。
