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);

和

Uri uri = Uri.parse("tel:xxxxxx");Intent intent = new Intent(Intent.ACTION_DIAL, uri);startActivity(intent);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");到通话记录界面：Intent intent=new Intent();intent.setAction(Intent.ACTION_CALL_BUTTON);startActivity(intent);  到联系人界面：Intent intent = new Intent();intent.setAction(Intent.ACTION_VIEW);intent.setData(Contacts.People.CONTENT_URI);startActivity(intent);同理，到应用：Intent intent= new Intent("com.android.contacts.action.LIST_STREQUENT");intent.setClassName("com.android.contacts","com.android.contacts.DialtactsActivity");  调用联系人界面：Intent intent = new Intent();intent.setAction(Intent.ACTION_PICK);intent.setData(Contacts.People.CONTENT_URI);startActivity(intent);   插入联系人Intent intent=new Intent(Intent.ACTION_EDIT,Uri.parse("content://com.android.contacts/contacts/"+"1"));startActivity(intent);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);  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);到应用：Intent intent = new Intent("android.intent.action.CONVERSATION");startActivity(intent);  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);   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);和uri = Uri.parse("tel:"+number);                intent = new Intent(Intent.ACTION_CALL,uri);                startActivity(intent);   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);  和 uri = Uri.parse("smsto:"+要发送短信的对方的number);                intent = new Intent(Intent.ACTION_SENDTO,uri);                startActivity(intent);和mIntent = new Intent(Intent.ACTION_VIEW);        mIntent.putExtra("address", c.getString(c.getColumnIndex(column)));        mIntent.setType("vnd.android-dir/mms-sms");        startActivity(mIntent);    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);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");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"));   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 application18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");

        i.setComponent(cn);         i.setAction("android.intent.action.MAIN");         startActivityForResult(i, RESULT_OK);20 添加到短信收件箱ContentValues cv = new ContentValues();                cv.put("type", "1");cv.put("address","短信地址");cv.put("body", "短信内容");getContentResolver().insert(Uri.parse("content://sms/inbox"), cv);   21 从sim卡或者联系人中查询Cursor cursor;        Uri uri;        if (type == 1) {            Intent intent = new Intent();            intent.setData(Uri.parse("content://icc/adn"));            uri = intent.getData();        } else            uri = People.CONTENT_URI;          cursor = activity.getContentResolver().query(uri, null, null, null, null);while (cursor.moveToNext()) { int peopleId = cursor.getColumnIndex(People._ID); int nameId = cursor.getColumnIndex(People.NAME); int phoneId = cursor.getColumnIndex(People.NUMBER);} 查看某个联系人，当然这里是ACTION_VIEW，如果为选择并返回action改为ACTION_PICK，当然处理intent时返回需要用到 startActivityforResult Uri personUri = ContentUris.withAppendedId(People.CONTENT_URI, ID);//最后的ID参数为联系人Provider中的数据库BaseID，即哪一行 Intent intent = new Intent(); intent.setAction(Intent.ACTION_VIEW); intent.setData(personUri); startActivity(intent); 22 删除uri = ContentUris.withAppendedId(People.CONTENT_URI, 联系人id);        int count = activity.getContentResolver().delete(uri, null, null);  23 添加到联系人：ContentValues cv = new ContentValues();ArrayList<ContentProviderOperation> operationList = new ArrayList<ContentProviderOperation>();ContentProviderOperation.Builder builder =

 ContentProviderOperation.newInsert(RawContacts.CONTENT_URI);                    builder.withValues(cv);                    operationList.add(builder.build());                    builder = ContentProviderOperation.newInsert(Data.CONTENT_URI);                    builder.withValueBackReference(StructuredName.RAW_CONTACT_ID, 0);                    builder.withValue(Data.MIMETYPE, StructuredName.CONTENT_ITEM_TYPE);                    builder.withValue(StructuredName.DISPLAY_NAME, "自定义联系人名");                    operationList.add(builder.build());                    builder = ContentProviderOperation.newInsert(Data.CONTENT_URI);                    builder.withValueBackReference(Phone.RAW_CONTACT_ID, 0);                    builder.withValue(Data.MIMETYPE, Phone.CONTENT_ITEM_TYPE);                    builder.withValue(Phone.NUMBER, "联系人的phonenumber");                    builder.withValue(Data.IS_PRIMARY, 1);                    operationList.add(builder.build());                    try {                        getContentResolver().applyBatch(ContactsContract.AUTHORITY, operationList);                    } catch (RemoteException e) {                        e.printStackTrace();                    } catch (OperationApplicationException e) {                        e.printStackTrace();                    } 23 选择一个图片 Intent intent = new Intent(Intent.ACTION_GET_CONTENT);intent.addCategory(Intent.CATEGORY_OPENABLE); intent.setType("image/*"); startActivityForResult(intent, 0);   24 调用Android设备的照相机，并设置拍照后存放位置Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File(Environment .getExternalStorageDirectory().getAbsolutePath()+"/cwj", android123 + ".jpg")));//存放位置为sdcard卡上cwj文件夹，文件名为android123.jpg格式startActivityForResult(intent, 0);  25 在market上搜索指定package name，比如搜索com.android123.cwj的写法如下 Uri uri = Uri.parse("market://search?q=pname:com.android123.cwj"); Intent intent = new Intent(Intent.ACTION_VIEW, uri); startActivity(intent);  26获取文件信息，并使用相对应软件打开view plainprivate void openFile(File f) {   Intent intent = new Intent();   intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);   intent.setAction(android.content.Intent.ACTION_VIEW);   String type = getMIMEType(f);   intent.setDataAndType(Uri.fromFile(f), type);   startActivity(intent); }     private String getMIMEType(File f){   String end = f       .getName()       .substring(f.getName().lastIndexOf(".") + 1,           f.getName().length()).toLowerCase();   String type = "";   if (end.equals("mp3") || end.equals("aac") || end.equals("aac")       || end.equals("amr") || end.equals("mpeg")       || end.equals("mp4"))   {     type = "audio";   } else if (end.equals("jpg") || end.equals("gif")       || end.equals("png") || end.equals("jpeg"))   {     type = "image";   } else   {     type = "*";   }   type += "/*";   return type;
