单挑通知持续时间

Question

是否可以将抬头通知的持续时间设置为无限制？ 现在它只显示 5 秒。已经尝试了不同的事情，例如更改类别。但持续时间始终为 5 秒。

这是我的代码：

Notification notification =
notificationBuilder
.setCategory(Notification.CATEGORY_CALL)
.setContentText("TKSE Werk Duisburg")
.setSmallIcon(R.drawable.ic_tk_individual_signet_logo)
.setOngoing(true)
.setAutoCancel(false)
.setVisibility(Notification.VISIBILITY_PUBLIC)
.setContentIntent(contentIntent)
.setCustomHeadsUpContentView(viewNotificationHeadsUp)                                                      .setCustomContentView(viewNotificationSmall)
.setPriority(Notification.PRIORITY_MAX)
.setVibrate(new long[20]).build();

尝试了与此线程相同的操作：控制 HeadsUp 的 Android 通知持续时间，但它对我没有帮助。

有趣的事实： 在我的开发者手机上，三星S5 mini ->显示没有时间限制 在另一部开发人员手机上，三星S7 ->显示5秒

这应该有效。我为通知类别添加了额外的onGoing(true)和category call。

NotificationManager notificationManager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
String NOTIFICATION_CHANNEL_ID = "my_channel_id_01";
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel notificationChannel = new NotificationChannel(NOTIFICATION_CHANNEL_ID, "My Notifications", NotificationManager.IMPORTANCE_MAX);
// Configure the notification channel.
notificationChannel.setDescription("Channel description");
notificationChannel.enableLights(true);
notificationChannel.setLightColor(Color.RED);
notificationChannel.setVibrationPattern(new long[]{0, 1000, 500, 1000});
notificationChannel.enableVibration(true);
notificationManager.createNotificationChannel(notificationChannel);
}
// assuming your main activity
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(MainActivity.this, NOTIFICATION_CHANNEL_ID);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, getIntent(), 0);
notificationBuilder.setAutoCancel(true)
.setDefaults(Notification.DEFAULT_ALL)
.setCategory(Notification.CATEGORY_CALL)
.setOngoing(true)
.setWhen(System.currentTimeMillis())
.setSmallIcon(R.drawable.ic_launcher)
.setTicker("Hearty365")
.setPriority(Notification.PRIORITY_MAX)
.setContentTitle("Default notification")
.setContentText("Lorem ipsum dolor sit amet, consectetur adipiscing elit.")
.setFullScreenIntent(pendingIntent,true)
.setContentInfo("Info");
notificationManager.notify(/*notification id*/1, notificationBuilder.build());

导入安卓.app.通知;用于设置通知类别(呼叫)

更新安卓 10

您需要为正在进行的通知添加优先级和类别。

val fullScreenIntent = Intent(this, CallActivity::class.java)
val fullScreenPendingIntent = PendingIntent.getActivity(this, 0,
fullScreenIntent, PendingIntent.FLAG_UPDATE_CURRENT)
val notificationBuilder =
NotificationCompat.Builder(this, CHANNEL_ID)
.setSmallIcon(R.drawable.notification_icon)
.setContentTitle("Incoming call")
.setContentText("[phone]")
.setPriority(NotificationCompat.PRIORITY_HIGH)
.setCategory(NotificationCompat.CATEGORY_CALL)
// Use a full-screen intent only for the highest-priority alerts where you
// have an associated activity that you would like to launch after the user
// interacts with the notification. Also, if your app targets Android 10
// or higher, you need to request the USE_FULL_SCREEN_INTENT permission in
// order for the platform to invoke this notification.
.setFullScreenIntent(fullScreenPendingIntent, true)
val incomingCallNotification = notificationBuilder.build()

我找到了这个页面并且它已经工作了

https://developer.android.com/training/notify-user/time-sensitive

val fullScreenIntent = Intent(this, CallActivity::class.java)
val fullScreenPendingIntent = PendingIntent.getActivity(this, 0,
fullScreenIntent, PendingIntent.FLAG_UPDATE_CURRENT)
val notificationBuilder =
NotificationCompat.Builder(this, CHANNEL_ID)
.setSmallIcon(R.drawable.notification_icon)
.setContentTitle("Incoming call")
.setContentText("[phone]")
.setPriority(NotificationCompat.PRIORITY_HIGH)
.setCategory(NotificationCompat.CATEGORY_CALL)

// Use a full-screen intent only for the highest-priority alerts where you
// have an associated activity that you would like to launch after the user
// interacts with the notification. Also, if your app targets Android 10
// or higher, you need to request the USE_FULL_SCREEN_INTENT permission in
// order for the platform to invoke this notification.
.setFullScreenIntent(fullScreenPendingIntent, true)

当然还有前台服务

val incomingCallNotification = notificationBuilder.build()

尝试该解决方案(您作为链接发布的解决方案...)，但是在进行更改后，有时不要忘记更改NOTIFICATION_ID如果通知 ID 未更改，通知的某些先前属性将保留..

所以 更改通知生成器的任何属性时更改通知 ID
