1.Intent的用法:
(1)用Action跳转
1、使用Action跳转,如果有一个程序的AndroidManifest.xml中的某一个 Activity的IntentFilter段中 定义了包含了相同的Action那么这个Intent就与这个目标Action匹配。如果这个IntentFilter段中没有定义 Type,Category,那么这个 Activity就匹配了。但是如果手机中有两个以上的程序匹配,那么就会弹出一个对话可框来提示说明。
Action 的值在Android中有很多预定义,如果你想直接转到你自己定义的Intent接收者,你可以在接收者的IntentFilter 中加入一个自定义的Action值(同时要设定 Category值为"android.intent.category.DEFAULT"),在你的Intent中设定该值为Intent的 Action,就直接能跳转到你自己的Intent接收者中。因为这个Action在系统中是唯一的。
2,data/type,你可以用Uri 来做为data,比如Uri uri = Uri.parse(http://www.google.com);
Intent i = new Intent(Intent.ACTION_VIEW,uri);手机的Intent分发过程中,会根据http://www.google.com 的scheme判断出数据类型type 。手机的Brower则能匹配它,在Brower的Manifest.xml中的IntenFilter中 首先有ACTION_VIEW Action,也能处理http:的type,
3, 至于分类Category,一般不要去在Intent中设置它,如果你写Intent的接收者,就在Manifest.xml的Activity的 IntentFilter中包含android.category.DEFAULT,这样所有不设置 Category(Intent.addCategory(String c);)的Intent都会与这个Category匹配。
4,extras(附 加信息),是其它所有附加信息的集合。使用extras可以为组件提供扩展信息,比如,如果要执行“发送电子邮件”这个动 作,可以将电子邮件的标题、正文等保存在extras里,传给电子邮件发送组件。
(2)用类名跳转
Intent负责对应用中一次操作的动作、动作涉及数据、附加数据进行描 述,Android则根据此Intent的描述, 负责找到对应的组件,将 Intent传递给调用的组件,并完成组件的调用。Intent在这里起着实现调用者与被调用者之间的解耦作用。Intent传递过程中,要找 到目标消费者(另一个Activity,IntentReceiver或Service),也就是Intent的响 应者。
不过注意用类名跳转,需要在AndroidManifest.xml中申明activity
<activity android:name="targetActivity"></activity>
2.几种Intent的用法
android 中intent是经常要用到的。不管是页面牵转,还是传递数据,或是调用外部程序,系统功能都要用到intent。在做了一些intent的例子之后,整理了一下intent,希望对大家有用。由于intent内容太多,不可能真的写全,难免会有遗落,以后我会随时更新。如果你们有疑问或新的intent内容,希望交流。
