An Intent is an object that provides runtime binding between separate components (such as two activities). The intent represents an app’s "intent to do something." You can use intents for a wide variety of tasks, but most often they’re used to start another activity.

Intent 是这样一个东西:它在不同的组件(如两个 activity)间提供运行时的绑定。intent 表示一个app“想要去做什么的意图”。你可以使用intent去做很多类型的任务,但通常它被用来启动另一个 activity

Inside the sendMessage() method, create an Intent to start an activity called DisplayMessageActivity:

Intent intent =newIntent(this,DisplayMessageActivity.class);

The constructor used here takes two parameters:

  • Context as its first parameter (this is used because the Activity class is a subclass of Context)
  • The Class of the app component to which the system should deliver the Intent (in this case, the activity that should be started)
