Android系統Intent的使用

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中指定程式要執行的動作（比如：view,edit,dial），以及程式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式，並執行該程式。 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); 複製代碼 顯示地圖: Uri uri = Uri.parse("geo:38.899533,-77.036476"); Intent it = new Intent(Intent.Action_VIEW,uri); startActivity(it); 複製代碼 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); 複製代碼 撥打到電話: 調用撥號程式 Uri uri = Uri.parse("tel:xxxxxx"); Intent it = new Intent(Intent.ACTION_DIAL, uri);   startActivity(it);   複製代碼 Uri uri = Uri.parse("tel.xxxxxx"); Intent it =new Intent(Intent.ACTION_CALL,uri); 要使用這個必須在設定檔中加入<uses-permission id="android.permission.CALL_PHONE" /> 複製代碼 發送SMS/MMS 調用傳送簡訊的程式 Intent it = new Intent(Intent.ACTION_VIEW);    it.putExtra("sms_body", "The SMS text");    it.setType("vnd.android-dir/mms-sms");    startActivity(it);  複製代碼 簡訊群發（多個號碼用;分隔開）      mobile = "1890000000;1890000001";   　　Intent intent = new Intent(Intent.ACTION_VIEW);  　　intent.putExtra("address", mobile);  　　//intent.putExtra("sms_body", "I am joe!");  　　intent.setType("vnd.android-dir/mms-sms");  　　startActivity(intent);    傳送簡訊 Uri uri = Uri.parse("smsto:0800000123");    Intent it = new Intent(Intent.ACTION_SENDTO, uri);    it.putExtra("sms_body", "The SMS text");    startActivity(it);   複製代碼 發送多媒體訊息 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); 複製代碼 發送Email Uri uri = Uri.parse("mailto:xxx@abc.com"); Intent it = new Intent(Intent.ACTION_SENDTO, uri); startActivity(it); 複製代碼 Intent it = new Intent(Intent.ACTION_SEND);    it.putExtra(Intent.EXTRA_EMAIL, "me@abc.com");    it.putExtra(Intent.EXTRA_TEXT, "The email body text");    it.setType("text/plain");    startActivity(Intent.createChooser(it, "Choose Email Client"));   複製代碼 Intent it=new Intent(Intent.ACTION_SEND);      String[] tos={"me@abc.com"};      String[] ccs={"you@abc.com"};      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"));    複製代碼 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")); 複製代碼 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); 複製代碼 Uri uri = Uri.withAppendedPath(MediaStore.Audio.Media.INTERNAL_CONTENT_URI, "1");    Intent it = new Intent(Intent.ACTION_VIEW, uri);    startActivity(it);   複製代碼 Uninstall 程式 Uri uri = Uri.fromParts("package", strPackageName, null);    Intent it = new Intent(Intent.ACTION_DELETE, uri);    startActivity(it); 複製代碼

uninstall apk

1. Uri uninstallUri = Uri.fromParts("package", "xxx", null);
3. returnIt = new Intent(Intent.ACTION_DELETE, uninstallUri);

複製代碼

install apk

1. Uri installUri = Uri.fromParts("package", "xxx", null);
3. returnIt = new Intent(Intent.ACTION_PACKAGE_ADDED, installUri);

複製代碼

play audio

1. Uri playUri = Uri.parse("file:///sdcard/download/everything.mp3");
3. returnIt = new Intent(Intent.ACTION_VIEW, playUri);

複製代碼

1. //發送附件
2. Intent it = new Intent(Intent.ACTION_SEND);  
3. it.putExtra(Intent.EXTRA_SUBJECT, "The email subject text");  
4. it.putExtra(Intent.EXTRA_STREAM, "file:///sdcard/eoe.mp3");  
5. sendIntent.setType("audio/mp3");  
6. startActivity(Intent.createChooser(it, "Choose Email Client"));

1. //搜尋應用
2. Uri uri = Uri.parse("market://search?q=pname:pkg_name");  
3. Intent it = new Intent(Intent.ACTION_VIEW, uri);  
4. startActivity(it);  
5. //where pkg_name is the full package path for an application  
7. //顯示指定應用的詳細頁面（這個好像不支援了，找不到app_id）
8. Uri uri = Uri.parse("market://details?id=app_id");  
9. Intent it = new Intent(Intent.ACTION_VIEW, uri);  
10. startActivity(it);  
11. //where app_id is the application ID, find the ID  
12. //by clicking on your application on Market home  
13. //page, and notice the ID from the address bar
