有什么方法可以启动我的应用程序的Android通知设置屏幕的意图(如下图所示)？或者一个简单的方法我可以制作一个PreferenceScreen项目,只需点击一下即可到达此处？

我一直致力于推送通知,我能够实现它并在状态栏上显示它,我面临的问题是我想显示它,即使手机是锁定的,在它所说的锁定屏幕下("拖动解锁"),我已经看过这样的通知,但无法找到任何示例.

示例: 就像您收到未接来电一样,它会在屏幕上的锁定按钮下显示.

码:

String ns = Context.NOTIFICATION_SERVICE;
NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns);
int icon = R.drawable.icon_launcher;
CharSequence tickerText = "MyApplication";
long when = System.currentTimeMillis();
Notification notification = new Notification(icon, tickerText, when);
notification.defaults |= Notification.DEFAULT_SOUND|Notification.DEFAULT_VIBRATE|Notification.DEFAULT_LIGHTS;;
CharSequence contentTitle = this.title;
CharSequence contentText = this.message;
Intent notificationIntent = new Intent(this, MainActivity.class);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);
mNotificationManager.notify(NOTICE_ID, notification);
