1.Intent的用法：
(1)用Action跳轉
1、使用Action跳轉，如果有一個程序的AndroidManifest.xml中的某一個 Activity的IntentFilter段中 定義了包含了相同的Action那麼這個Intent就與這個目標Action匹配。如果這個IntentFilter段中沒有定義 Type,Category，那麼這個 Activity就匹配了。但是如果手機中有兩個以上的程序匹配，那麼就會彈出一個對話可框來提示說明。
Action 的值在Android中有很多預定義，如果你想直接轉到你自己定義的Intent接收者，你可以在接收者的IntentFilter 中加入一個自定義的Action值（同時要設定 Category值爲"android.intent.category.DEFAULT"），在你的Intent中設定該值爲Intent的 Action,就直接能跳轉到你自己的Intent接收者中。因爲這個Action在系統中是唯一的。
2,data/type，你可以用Uri 來做爲data,比如Uri uri = Uri.parse(http://www.google.com);
Intent i = new Intent(Intent.ACTION_VIEW,uri);手機的Intent分發過程中，會根據http://www.google.com 的scheme判斷出數據類型type 。手機的Brower則能匹配它，在Brower的Manifest.xml中的IntenFilter中 首先有ACTION_VIEW Action,也能處理http:的type，
Intent i = new Intent(Intent.ACTION_VIEW,uri);手機的Intent分發過程中，會根據http://www.google.com 的scheme判斷出數據類型type 。手機的Brower則能匹配它，在Brower的Manifest.xml中的IntenFilter中 首先有ACTION_VIEW Action,也能處理http:的type，
3， 至於分類Category，一般不要去在Intent中設置它，如果你寫Intent的接收者，就在Manifest.xml的Activity的 IntentFilter中包含android.category.DEFAULT,這樣所有不設置 Category（Intent.addCategory(String c);）的Intent都會與這個Category匹配。
4,extras（附 加信息），是其它所有附加信息的集合。使用extras可以爲組件提供擴展信息，比如，如果要執行“發送電子郵件”這個動 作，可以將電子郵件的標題、正文等保存在extras裏，傳給電子郵件發送組件。
（2）用類名跳轉
Intent負責對應用中一次操作的動作、動作涉及數據、附加數據進行描 述，Android則根據此Intent的描述， 負責找到對應的組件，將 Intent傳遞給調用的組件，並完成組件的調用。Intent在這裏起着實現調用者與被調用者之間的解耦作用。Intent傳遞過程中，要找 到目標消費者（另一個Activity,IntentReceiver或Service），也就是Intent的響 應者。
Intent intent = new Intent();
intent.setClass(context, targetActivy.class);
//或者直接用 Intent intent = new Intent(context, targetActivity.class);
intent.setClass(context, targetActivy.class);
//或者直接用 Intent intent = new Intent(context, targetActivity.class);
startActivity(intent);
不過注意用類名跳轉，需要在AndroidManifest.xml中申明activity
<activity android:name="targetActivity"></activity>
2.幾種Intent的用法
android 中intent是經常要用到的。不管是頁面牽轉，還是傳遞數據，或是調用外部程序，系統功能都要用到intent。在做了一些intent的例子之後，整理了一下intent，希望對大家有用。由於intent內容太多，不可能真的寫全，難免會有遺落，以後我會隨時更新。如果你們有疑問或新的intent內容，希望交流。
