ringtone播放自定义的声音

主要是Uri的获取！！！

Uri leave = null;
        Ringtone r = RingtoneManager.getRingtone(getApplicationContext(), leave.parse("android.resource://" + getPackageName() + "/" +R.raw.audio)); 
        r.play();

下面程式是在引发Notification功能时，播放指定的声音

--------------------------------------------------------------------------------------------------------------------------------------

Url alert;
NotificationManager manger = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification();
notification.sound=alert.parse("android.resource://" + getPackageName() + "/" +R.raw.beepd);
manger.notify(1, notification);

--------------------------------------------------------------------------------------------------------------------------------------

不管什么资源，透过此方式就可以将raw指定给android内建的一些函数， 例如：

MediaPlayer,Notification,VideoView,ImageView，但是档案格式要符合Android的支援格式。

另个例子：

--------------------------------------------------------------------------------------------------------------------------------------

Url alert;

VideoView vv;

vv.setVideoURI=alert.parse("android.resource://" + getPackageName() + "/" +R.raw.myVideo);
