常用Intent

以下是常用到的Intent的URI及其示例,包含了大部分应用中用到的共用Intent

一、打开一个网页,类别是Intent.ACTION_VIEW

Uri uri = Uri.parse("http://www.android-study.com/");
Intent intent = new Intent(Intent.ACTION_VIEW, uri);

二、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);

三、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);

四、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);

五、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);

六、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);

七、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");

八、打开发邮件界面

Uri uri= Uri.parse("mailto:admin@android-study.com");
Intent intent = new Intent(Intent.ACTION_SENDTO, uri);

九、发邮件,与八不同这里是将邮件发送出去

Intent intent = new Intent(Intent.ACTION_SEND);
String[] tos = { "admin@android-study.com" };
String[] ccs = { "webmaster@android-study.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.com");
intent.putExtra(Intent.EXTRA_SUBJECT, "http://www.android-study.com");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 subject text");
intent.putExtra(Intent.EXTRA_STREAM, "file:///sdcard/mysong.mp3");
intent.setType("audio/mp3");
startActivity(Intent.createChooser(intent, "Choose Email Client"));

十、发短信

Uri uri= Uri.parse("tel:10086");
Intent intent = new Intent(Intent.ACTION_VIEW, uri);
intent.putExtra("sms_body", "I come from http://www.android-study.com");
intent.setType("vnd.Android-dir/mms-sms");

或者可以
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.putExtra("address", "电话号码,这里是电话");
intent.putExtra("sms_body","短信内容,短信");
intent.setType("vnd.android-dir/mms-sms");
startActivity(intent);


十一、直接发短信

Uri uri= Uri.parse("smsto://100861");
Intent intent = new Intent(Intent.ACTION_SENDTO, uri);
intent.putExtra("sms_body", "3g android http://www.android-study.com");

十二、发彩信

ri uri= Uri.parse("content://media/external/images/media/23");
Intent intent = new Intent(Intent.ACTION_SEND);
intent.putExtra("sms_body", "3g android http://www.android-study.com");
intent.putExtra(Intent.EXTRA_STREAM, uri);
intent.setType("image/png");

十三、# 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);
//where pkg_name is the full package path for an application
 
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);
//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

十四、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);
//where startLat, startLng, endLat, endLng are a long with 6 decimals like: 50.123456

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、进入联系人页面

Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setData(People.CONTENT_URI);
startActivity(intent);

十七、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);

十八、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(new File(Environment
.getExternalStorageDirectory().getAbsolutePath()+"/tucue", time + ".jpg")));
startActivityForResult(intent, ACTIVITY_GET_CAMERA_IMAGE);
