近日有个需求：用户要求把手机通知的提示音改为默认的手机铃声，改了好久终于做出了，做个记录。
代码如下：
/*** 启动通知*/public void showNotification(CharSequence title, CharSequence content, Class<?> jumpActivity) {mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);// 标题CharSequence contentTitle = title;// 内容CharSequence contentText = content;Intent intentDetail = new Intent(context, jumpActivity);/*** android api15以后用以下方法代替*/Notification.Builder builder1 = new Notification.Builder(context);builder1.setSmallIcon(R.mipmap.ic_launcher); //设置图标builder1.setTicker("显示第二个通知");builder1.setContentTitle(contentTitle); //设置标题builder1.setContentText(contentText); //消息内容builder1.setWhen(System.currentTimeMillis()); //发送时间builder1.setAutoCancel(true);//打开程序后图标消失PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intentDetail, PendingIntent.FLAG_UPDATE_CURRENT);builder1.setContentIntent(pendingIntent);Notification notification1 = builder1.getNotification();Uri uri = RingtoneManager.getActualDefaultRingtoneUri(context, RingtoneManager.TYPE_RINGTONE) ;notification1.sound=uri;mNotificationManager.notify(124, notification1); // 通过通知管理器发送通知}
