推荐答案

根据官方文档:

意图是要执行的操作的抽象描述.它可以与 startActivity 一起使用来启动 Activity ， broadcastIntent 并将其发送到任何感兴趣的 BroadcastReceiver 组件，以及 startService(Intent)或 bindService(Intent，ServiceConnection，int)与后台Service通信.

An intent is an abstract description of an operation to be performed. It can be used with startActivity to launch an Activity, broadcastIntent to send it to any interested BroadcastReceiver components, and startService(Intent) or bindService(Intent, ServiceConnection, int) to communicate with a background Service.

Intent 提供了一种在不同应用程序中的代码之间执行后期运行时绑定的功能.它最重要的用途是在启动活动时，可以将其视为活动之间的粘合剂.它基本上是一种被动数据结构，其中包含要执行的动作的抽象描述.

An Intent provides a facility for performing late runtime binding between the code in different applications. Its most significant use is in the launching of activities, where it can be thought of as the glue between activities. It is basically a passive data structure holding an abstract description of an action to be performed.

因此，您必须使用它来打开活动，而没有任何例外或变通方法，如果这样做，您将忽略整个系统体系结构.

So you have to use it to open activities with no exceptions or workarounds, if you do that, you are ignoring the entire system architecture.
