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： 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);<span style="font-family:Simsun;white-space: normal; background-color: rgb(255, 255, 255);"> </span> 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 [java] view plaincopy 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 [java] view plaincopy 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 [java] view plaincopy 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");

background-color: rgb(255, 255, 255);"> </span> 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<span style="font-family:Simsun;white-space: normal; background-color: rgb(255, 255, 255);"> </span> 18打开联系人列表 <1> Intent i = new Intent();

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);

} 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");

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; }
