Android系统Intent的使用

Android Intent的几种用法全面总结
Intent, 用法
Intent应该算是Android中特有的东西。你可以在Intent中指定程序要执行的动作（比如：view,edit,dial），以及程序执行到该动作时所需要的资料。都指定好后，只要调用startActivity()，Android系统会自动寻找最符合你指定要求的应用程序，并执行该程序。

下面列出几种Intent的用法
显示网页:
Uri uri = Uri.parse("http://www.google.com");

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

startActivity(it);
复制代码
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
路径规划:
Uri uri = Uri.parse("http://maps.google.com/maps?f=d&saddr=startLat%20startLng&daddr=endLat%20endLng&hl=en");

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

startActivity(it);
复制代码
拨打电话:
调用拨号程序
Uri uri = Uri.parse("tel:xxxxxx");

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

startActivity(it);
复制代码
Uri uri = Uri.parse("tel.xxxxxx");

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

要使用这个必须在配置文件中加入<uses-permission id="android.permission.CALL_PHONE" />
复制代码
发送SMS/MMS
调用发送短信的程序
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
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);
复制代码
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);
复制代码
发送Email

Uri uri = Uri.parse("mailto:xxx@abc.com");

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

startActivity(it);
复制代码
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"));
复制代码
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"));
复制代码
添加附件
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
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);
复制代码
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
Uninstall 程序
Uri uri = Uri.fromParts("package", strPackageName, null);

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

startActivity(it);
复制代码

uninstall apk

Uri uninstallUri = Uri.fromParts("package", "xxx", null);

returnIt = new Intent(Intent.ACTION_DELETE, uninstallUri);
复制代码

install apk

Uri installUri = Uri.fromParts("package", "xxx", null);

returnIt = new Intent(Intent.ACTION_PACKAGE_ADDED, installUri);
复制代码

play audio

Uri playUri = Uri.parse("file:///sdcard/download/everything.mp3");

returnIt = new Intent(Intent.ACTION_VIEW, playUri);
复制代码
//发送附件

Intent it = new Intent(Intent.ACTION_SEND);

it.putExtra(Intent.EXTRA_SUBJECT, "The email subject text");

it.putExtra(Intent.EXTRA_STREAM, "file:///sdcard/eoe.mp3");

sendIntent.setType("audio/mp3");

startActivity(Intent.createChooser(it, "Choose Email Client"));
//搜索应用

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

//显示指定应用的详细页面（这个好像不支持了，找不到app_id）

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
/** *//**
* 获得包安装Intent
* @param tempFile

*/
public static Intent getPackageInstallIntent(File tempFile)
{
Uri mPackageURI = Uri.fromFile(tempFile);
Intent in = new Intent();
in.setAction(Intent.ACTION_VIEW);
in.addCategory(Intent.CATEGORY_DEFAULT);
in
.setComponent(new ComponentName(
"com.android.packageinstaller",
"com.android.packageinstaller.PackageInstallerActivity"));
in.setDataAndType(mPackageURI,
"application/vnd.android.package-archive");
in.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
