android intent 隐式意图和显示意图(activity跳转)
-
显示意图要求必须知道被激活组件的包和class隐式意图仅仅须要知道跳转activity的动作和数据,就能够激活相应的组件
A 主activity B 接收跳转的activity
步骤
1:在主配置文件里声明B 至少要声明一个android:name属性
[html]
<activity
android:name=".DemoActivity"
android:label="@string/demoActivity" >
<intent-filter>
<!-- 隐士意图中指定intent的名字 自定义 可匹配多项 -->
<action android:name="com.itcast.intent.DemoActivity" />
<!-- 隐式intent须要指定的activity的类型,可自定义该值,须要在调用的时候相相应不写该项默觉得 android.intent.category.DEFAULT,可匹配多项 -->
<category android:name="android.intent.category.DEFAULT" />
<!-- 指定传想该activity数值的类型 和主机,假设指定该项,就必须在跳转activity的时候传入还数据和主机名 -->
<data
android:host="cn.itcast.demo"
android:scheme="itcast" />
</intent-filter>
</activity>
