Android Intent的用法（一）

轉：http://www.eoeandroid.com/thread-266-1-1.html

Intent應該算是Android中特有的東西。你可以在Intent中指定程序要執行的動作（比如：view,edit,dial），以及程序執行到該動作時所需要的資料。都指定好後，只要調用startActivity()，Android系統會自動尋找最符合你指定要求的應用程序，並執行該程序。

下面列出幾種Intent的用法
顯示網頁:

1. Uri uri = Uri.parse("http://www.google.com");
   
2. Intent it  = new Intent(Intent.ACTION_VIEW,uri);
   
3. startActivity(it);
