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);
