Intent有两种:implicit隐式 和 explicit显式 Explicit Intent 明确的指定了要启动的Acitivity 比如以下Java代码,明确指定了要启动B: Intent intent= new Intent(this, B.class) Implicit Intent 没有明确的指定要启动哪个Activity ,而是通过设置一些Intent Filter来让系统去筛选合适的Acitivity去启动。 当使用startActivity...

系统查找过滤过程如下图: When you create an explicit intent to start an activity or service, the system immediately starts the app component specified in the Intent object. Figure 1. Illustration of how an implicit intent is delivered through the system to start another activity: [1] Activity A...
(2)在src/com.application.implicitstart包下的ImplicitStart.java文件中,使用Intent隐式启动Activity,提示用户在http://后输入Web地址,以启动具有网页浏览功能的Activity。在该文件中编辑代码如下:第22行至第25行(加黑部分),在单击事件onClick(View view)方法中,首先,使用Intent构造方法创建一个实例intent,其中第一...
Implicit Intent This intent specifies an action that can be invoked by any app on the device which enables us to perform an action. It does not have exact knowledge about the landing component. It can open another app or its own app’s component and many other options exist. ...
It, in effect, filters in intents of a desired type, while filtering out unwanted intents — but only unwanted implicit intents (those that don't name a target class). An explicit intent is always delivered to its target, no matter what it contains; the filter is not consulted. But ...
Like the action, if a type is included in the intent (either explicitly or implicitly in its data), then this must be listed by the component as one it handles. For data that is not a content: URI and where no explicit type is included in the Intent, instead the scheme of the int...
// Explicit Intent by specifying its class name Intent i = new Intent(FirstActivity.this, SecondActivity.class); // Starts TargetActivity startActivity(i);Implicit IntentsThese intents do not name a target and the field for the component name is left blank. Implicit intents are often used ...
Intents allow us to communicate data between Android apps and implicit intents can also accept actions. One of those actions is the ACTION_SEND command which indicates we want to send data across apps. To send data, all you need to do is specify the data and its type, and the system ...
By categorizing customer intent into different types – including explicit, implicit, and inferred intent – you can develop a comprehensive view of customer behavior and preferences, ultimately shaping your strategies for maximum impact. Let’s explore further: Explicit intentExplicit intent refers to ...
