Intent应该算是Android中特有的东西。你能够在Intent中指定程序要运行的动作(比方:view,edit,dial),以及程序运行到该动作时所须要的资料。都指定好后,仅仅要调用startActivity(),Android系统会自己主动寻找最符合你指定要求的应用程序,并运行该程序。
以下列出几种Intent的使用方法 显示网页: Uri uri = Uri.parse("http://www.google.com"); Intent it = new Intent(Intent.ACTION_VIEW,uri); startActivity(it); 显示地图: Uri uri = Uri.parse("geo:38.899533,-77.036476"); Intent it = new Intent(Intent.Action_VIEW,uri); startActivity(it);
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);
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); 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里增加<uses-permission id="android.permission.CALL_PHONE" /
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);
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);
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");

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")); 加入附件 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")); 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);
Uninstall 程序 Uri uri = Uri.fromParts("package", strPackageName, null); Intent it = new Intent(Intent.ACTION_DELETE, uri); startActivity(it);

//where pkg_name is the full package path for an application
//显示指定应用的具体页面(这个好像不支持了,找不到app_id)
Uri uri = Uri.parse("market://details?id=app_id");
