Android Intent的幾種用法全面總結

Intent, 用法

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: Uri uri = Uri.parse("http://www.google.com"); Intent it??= new Intent(Intent.ACTION_VIEW,uri); startActivity(it); 顯示地圖: Uri uri = Uri.parse("geo:38.899533,-77.036476"); Intent it = new Intent(Intent.Action_VIEW,uri); startActivity(it); 路徑規劃: Uri uri = Uri.parse("http://maps.google.com/maps?f=d&saddr=startLat%20startLng&daddr=endLat%20endLng&hl=en"); Intent it = new Intent(Intent.ACTION_VIEW,URI); startActivity(it); 撥打電話: 調用撥號程序 Uri uri = Uri.parse("tel:xxxxxx"); Intent it = new Intent(Intent.ACTION_DIAL, uri);?? startActivity(it);?? Uri uri = Uri.parse("tel.xxxxxx"); Intent it =new Intent(Intent.ACTION_CALL,uri); 要使用這個必須在配置文件中加入<uses-permission id="android.permission.CALL_PHONE" /> 發送SMS/MMS 調用發送短信的程序 Intent it = new Intent(Intent.ACTION_VIEW);? ? it.putExtra("sms_body", "The SMS text");? ? it.setType("vnd.android-dir/mms-sms");? ? startActivity(it);?? 發送短信 Uri uri = Uri.parse("smsto:0800000123");? ?
