本文介绍在安卓开发中经常遇到的一些Intent的URI及其示例，包含了大部分应用中用到的共用Intent，希望本文能对广大安卓开发者有所帮助。

   一、直接拨打电话，与三不同的是，这个直接拨打电话，而不是打开拨号界面

Uri uri = Uri.parse(＂tel:10086＂);
Intent intent = new Intent(Intent.ACTION_CALL, uri);
   二、打开拨号界面，类型是Intent.ACTION_DIAL

Uri uri = Uri.parse(＂tel:10086＂);
Intent intent = new Intent(Intent.ACTION_DIAL, uri);
   三、打开一个网页，类别是Intent.ACTION_VIEW

Uri uri = Uri.parse(＂http://www.android-study.net/＂);
Intent intent = new Intent(Intent.ACTION_VIEW, uri);
   四、卸载一个应用，Intent的类别是Intent.ACTION_DELETE

Uri uri = Uri.fromParts(＂package＂, ＂xxx＂, null);
Intent intent = new Intent(Intent.ACTION_DELETE, uri);
   五、打开地图并定位到一个点

Uri uri = Uri.parse(＂geo:52.76,-79.0342＂);
Intent intent = new Intent(Intent.ACTION_VIEW, uri);
   六、播放音频文件

Uri uri = Uri.parse(＂file:///sdcard/download/everything.mp3＂);
Intent intent = new Intent(Intent.ACTION_VIEW, uri);
intent.setType(＂audio/mp3＂);
   七、安装应用程序,Intent的类别是Intent.ACTION_PACKAGE_ADDED

Uri uri = Uri.fromParts(＂package＂, ＂xxx＂, null);
Intent intent = new Intent(Intent.ACTION_PACKAGE_ADDED, uri);
   八、打开发邮件界面

Uri uri= Uri.parse(＂mailto:androidstudynet@126.com＂);
Intent intent = new I
4000
ntent(Intent.ACTION_SENDTO, uri);
   九、发邮件,与上一个不同这里是将邮件发送出去

Intent intent = new Intent(Intent.ACTION_SEND);
String[] tos = { ＂androidstudynet@126.com＂};
String[] ccs = { ＂aaa@126.com＂};
intent.putExtra(Intent.EXTRA_EMAIL, tos);
intent.putExtra(Intent.EXTRA_CC, ccs);
intent.putExtra(Intent.EXTRA_TEXT, ＂I come from http://www.android-study.net＂); intent.putExtra(Intent.EXTRA_SUBJECT, ＂http://www.android-study.net＂);intent.setType(＂message/rfc882＂);
Intent.createChooser(intent, ＂Choose Email Client＂);

//发送带附件的邮件

Intent intent = new Intent(Intent.ACTION_SEND);
intent.putExtra(Intent.EXTRA_SUBJECT, ＂The email subjecttext＂);
intent.putExtra(Intent.EXTRA_STREAM, ＂file:///sdcard/mynusic.mp3＂);
intent.setType(＂audio/mp3＂);
startActivity(Intent.createChooser(intent, ＂Choose EmailClient＂));

十、直接发短信
Uri uri= Uri.parse(＂smsto://100861＂);

Intent intent = new Intent(Intent.ACTION_SEND);
intent.putExtra(＂sms_body＂, ＂安卓发送邮件测试 http://www.android-study.net＂); intent.putExtra(Intent.EXTRA_STREAM, uri);
intent.setType(＂image/png＂);
   十二、发短信

Uri uri= Uri.parse(＂tel:10086＂);
Intent intent = new Intent(Intent.ACTION_VIEW, uri);
intent.putExtra(＂sms_body＂, ＂安卓发送邮件测试 http://www.android-study.net＂); intent.setType(＂vnd.Android-dir/mms-sms＂);

    十三、调用相册
public static final String MIME_TYPE_IMAGE_JPEG = ＂image/*＂;
public static final int ACTIVITY_GET_IMAGE = 0;
Intent getImage = new Intent(Intent.ACTION_GET_CONTENT);
getImage.addCategory(Intent.CATEGORY_OPENABLE);
getImage.setType(MIME_TYPE_IMAGE_JPEG);
startActivityForResult(getImage, ACTIVITY_GET_IMAGE);
    十四、#Market 相关

1 //寻找某个应用
Uri uri = Uri.parse(＂market://search?q=pname:pkg_name＂);
Intent it = new Intent(Intent.ACTION_VIEW, uri);
startActivity(it);

2 //显示某个应用的相关信息
Uri uri = Uri.parse(＂market://details?id=app_id＂);
Intent it = new Intent(Intent.ACTION_VIEW, uri);
startActivity(it);   十五、安装指定apk
public void setupAPK(String apkname){
String fileName = Environment.getExternalStorageDirectory() + ＂/＂ +apkname;
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(new File(fileName)),＂application/vnd.android.package-archive＂);
mService.startActivity(intent);
}
   十六、路径规划

Uri uri = Uri.parse(＂http://maps.google.com/maps?f=d&saddr=startLatstartLng&daddr=endLat endLng&hl=en＂);
Intent it = new Intent(Intent.ACTION_VIEW, uri);
startActivity(it);
   十七、进入联系人页面

Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setData(People.CONTENT_URI);
startActivity(intent);
   十八、查看指定联系人

Uri personUri = ContentUris.withAppendedId(People.CONTENT_URI,info.id);// info.id联系人ID
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setData(personUri);
startActivity(intent);   十九、调用系统相机应用程序，并存储拍下来的照片
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
time = Calendar.getInstance().getTimeInMillis();
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(newFile(Environment.getExternalStorageDirectory().getAbsolutePath()+＂/tucue＂,time + ＂.jpg＂)));
startActivityForResult(intent, ACTIVITY_GET_CAMERA_IMAGE);
