现在开发中的功能需要直接跳转到拨号、联系人、短信界面等等，查找了很多资料，自己整理了一下。         首先，我们先看拨号界面，代码如下：Intent intent =new Intent();               intent.setAction("android.intent.action.CALL_BUTTON");               startActivity(intent);复制代码和Uri uri = Uri.parse("tel:xxxxxx");    Intent intent = new Intent(Intent.ACTION_DIAL, uri);      startActivity(intent);  复制代码两者都行   但是如果是跳转到应用,使用一下代码：Intent intent= new Intent("android.intent.action.DIAL");    intent.setClassName("com.android.contacts","com.android.contacts.DialtactsActivity");复制代码到通话记录界面：Intent intent=new Intent();   intent.setAction(Intent.ACTION_CALL_BUTTON);   startActivity(intent);  复制代码到联系人界面：Intent intent = new Intent();    intent.setAction(Intent.ACTION_VIEW);    intent.setData(Contacts.People.CONTENT_URI);    startActivity(intent);复制代码同理，到应用：Intent intent= new Intent("com.android.contacts.action.LIST_STREQUENT");    intent.setClassName("com.android.contacts","com.android.contacts.DialtactsActivity");复制代码调用联系人界面：Intent intent = new Intent();    intent.setAction(Intent.ACTION_PICK);    intent.setData(Contacts.People.CONTENT_URI);    startActivity(intent);   复制代码插入联系人Intent intent=new Intent(Intent.ACTION_EDIT,Uri.parse("content://com.android.contacts/contacts/"+"1"));   startActivity(intent);  复制代码到联系人列表界面   Intent intent = new Intent(Intent.ACTION_INSERT_OR_EDIT);               intent.setType("vnd.android.cursor.item/person");               intent.setType("vnd.android.cursor.item/contact");               intent.setType("vnd.android.cursor.item/raw_contact");               intent.putExtra(android.provider.ContactsContract.Intents.Insert.NAME, name);               intent.putExtra(android.provider.ContactsContract.Intents.Insert.COMPANY,company);               intent.putExtra(android.provider.ContactsContract.Intents.Insert.PHONE, tel);               intent.putExtra(android.provider.ContactsContract.Intents.Insert.PHONE_TYPE, 3);复制代码到短信界面：Intent intent = new Intent(Intent.ACTION_VIEW);                   intent.setType("vnd.android-dir/mms-sms");   //              intent.setData(Uri.parse("content://mms-sms/conversations/"));//此为号码                   startActivity(intent);  复制代码到应用：Intent intent = new Intent("android.intent.action.CONVERSATION");   startActivity(intent);  复制代码以下是在网上找到的其他方法：1.从google搜索内容Intent intent = new Intent();    intent.setAction(Intent.ACTION_WEB_SEARCH);    intent.putExtra(SearchManager.QUERY,"searchString")    startActivity(intent);   复制代码2.浏览网页Uri uri = Uri.parse("http://www.google.com");    Intent it   = new Intent(Intent.ACTION_VIEW,uri);    startActivity(it);复制代码3.显示地图Uri uri = Uri.parse("geo:38.899533,-77.036476");    Intent it = new Intent(Intent.Action_VIEW,uri);    startActivity(it);   复制代码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);  复制代码5.拨打电话Uri uri = Uri.parse("tel:xxxxxx");    Intent it = new Intent(Intent.ACTION_DIAL, uri);      startActivity(it);  复制代码和uri = Uri.parse("tel:"+number);                     intent = new Intent(Intent.ACTION_CALL,uri);                     startActivity(intent);  复制代码其中不同自己试验一下就知道了。 6.调用发短信的程序Intent it = new Intent(Intent.ACTION_VIEW);      it.putExtra("sms_body", "The SMS text");      it.setType("vnd.android-dir/mms-sms");      startActivity(it);复制代码和uri = Uri.parse("smsto:"+要发送短信的对方的number);                     intent = new Intent(Intent.ACTION_SENDTO,uri);                     startActivity(intent);   复制代码和mIntent = new Intent(Intent.ACTION_VIEW);             mIntent.putExtra("address", c.getString(c.getColumnIndex(column)));             mIntent.setType("vnd.android-dir/mms-sms");             startActivity(mIntent);   复制代码7.发送短信Uri uri = Uri.parse("smsto:0800000123");      Intent it = new Intent(Intent.ACTION_SENDTO, uri);      it.putExtra("sms_body", "The SMS text");      startActivity(it);    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);   复制代码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);   复制代码9.发送EmailUri 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");        it.putExtra(Intent.EXTRA_SUBJECT, "The email subject text");        it.setType("message/rfc822");        startActivity(Intent.createChooser(it, "Choose Email Client"));         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"));   复制代码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);   复制代码11.uninstall apkUri uri = Uri.fromParts("package", strPackageName, null);      Intent it = new Intent(Intent.ACTION_DELETE, uri);      startActivity(it);  复制代码12.install apkUri installUri = Uri.fromParts("package", "xxx", null);    returnIt = new Intent(Intent.ACTION_PACKAGE_ADDED, installUri);  复制代码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);复制代码14.从gallery选取图片Intent i = new Intent();            i.setType("image/*");            i.setAction(Intent.ACTION_GET_CONTENT);            startActivityForResult(i, 11);   复制代码15. 打开录音机Intent mi = new Intent(Media.RECORD_SOUND_ACTION);             startActivity(mi);复制代码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    复制代码刚才找app id未果，结果发现用package name也可以 Uri uri = Uri.parse("market://details?id=
