intent详解

intent在google的sdk中原文释义是：An intent is an abstract description of an
operation to be
performed,intent就是对将要进行的东东的一种抽象描述，我感觉intent在开发中起着穿针引线的强大功能，起着信使的作用，学习中几乎
处处都要用到这个东东，今天特地将平时总结的写了出来，顺便自己又复习了一下。

1.浏览网页

Uri uri = Uri.parse(“http://www.focuser.org”);

Intent it = new Intent(Intent.ACTION_VIEW,uri);

startActivity(it);

2.从google搜索内容

Intent intent = new Intent();

intent.setAction(Intent.ACTION_WEB_SEARCH);

intent.putExtra(SearchManager.QUERY,”searchString”)

startActivity(intent);

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”);

it.setType(“vnd.android-dir/mms-sms”);

startActivity(it);

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:qizi@focuser.org”);

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 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(“org.focuser.one”,

“org.focuser.two”);

i.setComponent(cn);

i.setAction(“android.intent.action.MAIN”);

startActivityForResult(i, RESULT_OK);
