Android Intent的幾種用法全面總結(jié)
Intent應(yīng)該算是Android中特有的東西。你可以在Intent中指定程序要執(zhí)行的動作（比如：view,edit,dial），以及程序執(zhí)行到該動作時所需要的資料。都指定好后，只要調(diào)用startActivity()，Android系統(tǒng)會自動尋找最符合你指定要求的應(yīng)用程序，并執(zhí)行該程序。
下面列出幾種Intent的用法
顯示網(wǎng)頁:
- Uri uri = Uri.parse("http://www.google.com");
- Intent it = new Intent(Intent.ACTION_VIEW,uri);
- startActivity(it);

- Intent it = new Intent(Intent.Action_VIEW,uri);
- startActivity(it);
