android 中 intent 是经常要用到的。不管是页面牵转,还是传递数据,或是调用外部程序,系统功能都要用到 intent。
1.从 google 搜索内容
Intent intent = new Intent();intent.setAction(Intent.ACTION_WEB_SEARCH);
intent.putExtra(SearchManager.QUERY,"searchString")
startActivity(intent);
2.浏览网页
Uri uri = Uri.parse("http://www.google.com");Intent it = new Intent(Intent.ACTION_VIEW,uri);
startActivity(it);
3.显示地图
Uri uri = Uri.parse("geo:38.899533,-77.036476");Intent it = new Intent(Intent.Action_VIEW,uri);
startActivity(it);
4.路径规划
Uri uri = Uri.parse("http://maps.google.com/maps?f=dsaddr=startLat%20startLng&daddr=endLat%20endLng&hl=en");
Intent it = new Intent(Intent.ACTION_VIEW,URI);
startActivity(it);
5.拨打电话
Uri uri = Uri.parse("tel:xxxxxx");Intent it = new Intent(Intent.ACTION_DIAL, uri);
startActivity(it);
6.调用发短信的程序
Intent it = new Intent(Intent.ACTION_VIEW);it.putExtra("sms_body", "The SMS text");

startActivity(it);
String body="this is sms demo";
Intent mmsintent = new Intent(Intent.ACTION_SENDTO, Uri.fromParts("smsto", number, null));
mmsintent.putExtra(Messaging.KEY_ACTION_SENDTO_MESSAGE_BODY, body);
mmsintent.putExtra(Messaging.KEY_ACTION_SENDTO_COMPOSE_MODE, true);
mmsintent.putExtra(Messaging.KEY_ACTION_SENDTO_EXIT_ON_SENT, true);
startActivity(mmsintent);
8.发送彩信
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);
StringBuilder sb = new StringBuilder();
sb.append("file://");
sb.append(fd.getAbsoluteFile());
Intent intent = new Intent(Intent.ACTION_SENDTO, Uri.fromParts("mmsto", number, null));
// Below extra datas are all optional.
intent.putExtra(Messaging.KEY_ACTION_SENDTO_MESSAGE_SUBJECT, subject);
intent.putExtra(Messaging.KEY_ACTION_SENDTO_MESSAGE_BODY, body);
intent.putExtra(Messaging.KEY_ACTION_SENDTO_CONTENT_URI, sb.toString());
intent.putExtra(Messaging.KEY_ACTION_SENDTO_COMPOSE_MODE, composeMode);
intent.putExtra(Messaging.KEY_ACTION_SENDTO_EXIT_ON_SENT, exitOnSent);
startActivity(intent);
9.发送 Email
Uri uri = Uri.parse("mailto:xxx@abc.com");Intent it = new Intent(Intent.ACTION_SENDTO, uri);
startActivity(it);
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"));
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");

sendIntent.setType("audio/mp3");
startActivity(Intent.createChooser(it, "Choose Email Client"));
10.播放多媒体
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);
11.uninstall apk
Uri uri = Uri.fromParts("package", strPackageName, null);Intent it = new Intent(Intent.ACTION_DELETE, uri);
startActivity(it);
12.install apk
Uri installUri = Uri.fromParts("package", "xxx", null);returnIt = new Intent(Intent.ACTION_PACKAGE_ADDED, installUri);
13. 打开照相机
<1>Intent i = new Intent(Intent.ACTION_CAMERA_BUTTON, null);this.sendBroadcast(i);
<2>long dateTaken = System.currentTimeMillis();
String name = createName(dateTaken) + ".jpg";
fileName = folder + name;
ContentValues values = new ContentValues();
values.put(Images.Media.TITLE, fileName);
values.put("_data", fileName);
values.put(Images.Media.PICASA_ID, fileName);
values.put(Images.Media.DISPLAY_NAME, fileName);
values.put(Images.Media.DESCRIPTION, fileName);
values.put(Images.ImageColumns.BUCKET_DISPLAY_NAME, fileName);
Uri photoUri = getContentResolver().insert(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
Intent inttPhoto = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
inttPhoto.putExtra(MediaStore.EXTRA_OUTPUT, photoUri);
startActivityForResult(inttPhoto, 10);
14.从 gallery 选取图片
Intent i = new Intent();i.setType("image/*");
i.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(i, 11);
15. 打开录音机
Intent mi = new Intent(Media.RECORD_SOUND_ACTION);startActivity(mi);
16.显示应用详细列表
Uri uri = Uri.parse("market://details?id=app_id");Intent it = new Intent(Intent.ACTION_VIEW, uri);
startActivity(it);
//where app_id is the application ID, find the ID
//by clicking on your application on Market home
//page, and notice the ID from the address bar
刚才找 app id 未果,结果发现用 package name 也可以
Uri uri = Uri.parse("market://details?id=<packagename>");
这个简单多了
17 寻找应用
Uri uri = Uri.parse("market://search?q=pname:pkg_name");Intent it = new Intent(Intent.ACTION_VIEW, uri);
startActivity(it);
//where pkg_name is the full package path for an application
18 打开联系人列表
<1>Intent i = new Intent();
i.setAction(Intent.ACTION_GET_CONTENT);
i.setType("vnd.android.cursor.item/phone");
startActivityForResult(i, REQUEST_TEXT);
<2>
Uri uri = Uri.parse("content://contacts/people");
Intent it = new Intent(Intent.ACTION_PICK, uri);
startActivityForResult(it, REQUEST_TEXT);
19 打开另一程序
Intent i = new Intent();ComponentName cn = new ComponentName("com.yellowbook.android2",
"com.yellowbook.android2.AndroidSearch");
i.setComponent(cn);
i.setAction("android.intent.action.MAIN");
startActivityForResult(i, RESULT_OK);
20.调用系统编辑添加联系人(高版本 SDK 有效):
Intent it = new Intent(Intent.ACTION_INSERT_OR_EDIT);it.setType("vnd.android.cursor.item/contact");
// it.setType(Contacts.CONTENT_ITEM_TYPE);
it.putExtra("name", "myName");
it.putExtra(android.provider.Contacts.Intents.Insert.COMPANY, "organization");
it.putExtra(android.provider.Contacts.Intents.Insert.EMAIL, "email");
it.putExtra(android.provider.Contacts.Intents.Insert.PHONE,"homePhone");
it.putExtra( android.provider.Contacts.Intents.Insert.SECONDARY_PHONE,
"mobilePhone");
it.putExtra( android.provider.Contacts.Intents.Insert.TERTIARY_PHONE,
"workPhone");
it.putExtra(android.provider.Contacts.Intents.Insert.JOB_TITLE,"title");
startActivity(it);
21.调用系统编辑添加联系人(全有效):
Intent intent = new Intent(Intent.ACTION_INSERT_OR_EDIT);intent.setType(People.CONTENT_ITEM_TYPE);
intent.putExtra(Contacts.Intents.Insert.NAME, "My Name");
intent.putExtra(Contacts.Intents.Insert.PHONE, "+1234567890");
intent.putExtra(Contacts.Intents.Insert.PHONE_TYPE,
Contacts.PhonesColumns.TYPE_MOBILE);
intent.putExtra(Contacts.Intents.Insert.EMAIL, "com@com.com");
intent.putExtra(Contacts.Intents.Insert.EMAIL_TYPE,
Contacts.ContactMethodsColumns.TYPE_WORK);
startActivity(intent);
22(更新)
//直接打电话出去Uri uri = Uri.parse("tel:0800000123");
Intent it = new Intent(Intent.ACTION_CALL, uri);
startActivity(it);
//用這個,要在 AndroidManifest.xml 中,加上
//<uses-permission id="android.permission.CALL_PHONE" />
23.最基本的 share 信息的 intent,可以传一段 text 信息到各个手机上已安装程序:如
SMS,Email,sina 微波,米聊,facebook,twitter 等等Intent it = new Intent(Intent.ACTION_SEND);
it.putExtra(Intent.EXTRA_TEXT, "The email subject text");
it.setType("text/plain");
startActivity(Intent.createChooser(it, "Choose Email Client"));
24.调用 skype 的 intent
方法 1:老版,新版不可用,可能是因为 skype 的 activity 结构变动://
Intent sky = new Intent("android.intent.action.CALL_PRIVILEGED");
sky.setClassName("com.skype.raider",
"com.skype.raider.contactsync.ContactSkypeOutCallStartActivity");
sky.setData(Uri.parse("tel:" + phone));
startActivity(sky);
方法 2:打开到 skype 的 main page:
//
PackageManager packageManager = getActivity().getPackageManager();
Intent skype = packageManager.getLaunchIntentForPackage("com.skype.raider");
skype.setData(Uri.parse("tel:65465446"));
startActivity(skype);
方法 3:传入号码,直接进入 skype 拨号画面并打电话:
Intent intent = new Intent("android.intent.action.CALL_PRIVILEGED");
intent.setClassName("com.skype.raider",
"com.skype.raider.Main");
intent.setData(Uri.parse("tel:" + phone));
startActivity(intent);
一些常用的Intent:
geo:0,0?q=street+addressIntent.ACTION_VIEW打开地图应用程序并显示指定的地址
http://web_addressIntent.ACTION_VIEW打开浏览器程序并显示指定的URL
https://web_addressIntent.ACTION_VIEW打开浏览器程序并显示指定的URL
tel:phone_numberIntent.ACTION_CALL打开电话应用程序并拨打指定的电话号码
tel:phone_numberIntent.ACTION_DIAL打开电话应用程序并拨下指定的电话号码
voicemail:Intent.ACTION_DIAL打开电话应用程序并拨下指定语音邮箱的电话号码
plain_textIntent.ACTION_WEB_SEARCH打开浏览器程序并使用Google搜索引擎搜索
