Android Intent的幾種用法全面總結

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。都指定好后,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,并執行該程序。

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);
顯示地圖:
  1. Uri uri = Uri.parse("geo:38.899533,-77.036476");
  2. Intent it = new Intent(Intent.Action_VIEW,uri);
  3. startActivity(it);
路徑規劃:
  1. Uri uri = Uri.parse("http://maps.google.com/maps?f=d&saddr=startLat%20startLng&daddr=endLat%20endLng&hl=en");
