android intent 隱式意圖和顯示意圖(activity跳轉)
-
顯示意圖要求必須知道被激活組件的包和class
隱式意圖只需要知道跳轉activity的動作和數據,就可以激活對應的組件
A 主activity B 接收跳轉的activity
步驟
1:在主配置文件中聲明B 至少要聲明一個android:name屬性
[html]
<activity
android:name=".DemoActivity"
android:label="@string/demoActivity" >
<intent-filter>
<!-- 隱士意圖中指定intent的名字 自己定義 可匹配多項 -->
<action android:name="com.itcast.intent.DemoActivity" />
<!-- 隱式intent需要指定的activity的類型,可自己定義該值,需要在調用的時候相對應不寫該項默認爲 android.intent.category.DEFAULT,可匹配多項 -->
<category android:name="android.intent.category.DEFAULT" />
<!-- 指定傳想該activity數值的類型 和主機,如果指定該項,就必須在跳轉activity的時候傳入還數據和主機名 -->
<data
android:host="cn.itcast.demo"
android:scheme="itcast" />
</intent-filter>
</activity>

//將電話號碼傳入撥號程序
Intent intent = new Intent(Intent.ACTION_DIAL, Uri .parse("tel:123456789"));
startActivity(intent);
|
//直接的撥打相應號碼
Intent intent = new Intent(Intent.ACTION_CALL, Uri .parse("tel:123456789"));
