Android Intent的幾種用法全面總結

編輯：關於Android編程

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:

Uri uri = Uri.parse("http://www.google.com");
Intent it = new Intent(Intent.ACTION_VIEW,uri);
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");
  2. Intent it = new Intent(Intent.ACTION_VIEW,URI);
  3. startActivity(it); 撥打電話:
    調用撥號程序
    1. Uri uri = Uri.parse("tel:xxxxxx");
    2. Intent it = new Intent(Intent.ACTION_DIAL, uri);
    3. startActivity(it);
      1. Uri uri = Uri.parse("tel.xxxxxx");
      2. Intent it =new Intent(Intent.ACTION_CALL,uri);
      3. 要使用這個必須在配置文件中加入發送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");
        Intent it = new Intent(Intent.ACTION_SENDTO, uri);
        it.putExtra("sms_body", "The SMS text");
        startActivity(it); 發送彩信
        
        Uri uri = Uri.parse("content://media/external/images/media/23");
        Intent it = new Intent(Intent.ACTION_SEND);
        it.putExtra("sms_body", "some text");
        it.putExtra(Intent.EXTRA_STREAM, uri);
        it.setType("image/png");
        startActivity(it); 發送Email
        
        Uri uri = Uri.parse("mailto:[email protected]");
        Intent it = new Intent(Intent.ACTION_SENDTO, uri);
        startActivity(it);
        
        Intent it = new Intent(Intent.ACTION_SEND);
        it.putExtra(Intent.EXTRA_EMAIL, "[email protected]");
        it.putExtra(Intent.EXTRA_TEXT, "The email body text");
        it.setType("text/plain");
        startActivity(Intent.createChooser(it, "Choose Email Client"));
        
        Intent it=new Intent(Intent.ACTION_SEND);
        String[] tos={"[email protected]"};
        String[] ccs={"[email protected]"};
        it.putExtra(Intent.EXTRA_EMAIL, tos);
        it.putExtra(Intent.EXTRA_CC, ccs);
        it.putExtra(Intent.EXTRA_TEXT, "The email body text");
        it.putExtra(Intent.EXTRA_SUBJECT, "The email subject text");
        it.setType("message/rfc822");
        startActivity(Intent.createChooser(it, "Choose Email Client")); 添加附件
        
        Intent it = new Intent(Intent.ACTION_SEND);
        it.putExtra(Intent.EXTRA_SUBJECT, "The email subject text");
        it.putExtra(Intent.EXTRA_STREAM, "file:///sdcard/mysong.mp3");
        sendIntent.setType("audio/mp3");
        startActivity(Intent.createChooser(it, "Choose Email Client")); 播放多媒體
        
        Intent it = new Intent(Intent.ACTION_VIEW);
        Uri uri = Uri.parse("file:///sdcard/song.mp3");
        it.setDataAndType(uri, "audio/mp3");
        startActivity(it);
        
        Uri uri = Uri.withAppendedPath(MediaStore.Audio.Media.INTERNAL_CONTENT_URI, "1");
        Intent it = new Intent(Intent.ACTION_VIEW, uri);
        startActivity(it); Uninstall 程序
        
        Uri uri = Uri.fromParts("package", strPackageName, null);
        Intent it = new Intent(Intent.ACTION_DELETE, uri);
        startActivity(it);
