Android:如何将Parcelable对象传递给Intent并使用bundle的getParcelable方法? [英] Android: How to pass Parcelable object to intent and use getParcelable method of bundle?

问题描述

为什么捆绑包具有getParcelableArrayList，getParcelable方法；但 Intent仅具有putParcelableArrayListExtra方法? 我只能传送一个元素的object<T>而不传送ArrayList吗? 那么，getParcelable是做什么的?

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?

推荐答案

Intent提供了一堆重载

Intent provides bunch of overloading putExtra() methods.

假设您有一个Foo类正确地实现了Parcelable，可将其放入Activity中的Intent中:

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);

要从其他活动中获取它:

To get it from intent in another activity:

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