是否可以将 headsup 通知的持续时间设置为无限制?现在它只显示 5 秒。已经尝试过不同的事情,比如改变类别。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();
在这个线程上尝试了同样的事情:Controlling Android Notification Duration for HeadsUp但这对我没有帮助。
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三星 S7 的另一台开发者手机上 -> 显示 5 秒
最佳答案
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());
附言。导入 android.app.Notification;用于设置通知类别(调用)
更新 Android 10
您需要为持续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("(919) 555-1234")
.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()
关于java - HeadsUp 的通知持续时间,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/48862052/
是否可以将 headsup 通知的持续时间设置为无限制?现在它只显示 5 秒。已经尝试过不同的事情,比如改变类别。但持续时间始终为 5 秒。 这是我的代码: Notification notifica
我有一个通知,使用以下代码呈现: // Create the notification android.app.Notification systemNotification = ne
我是一名优秀的程序员,十分优秀!
