要实现Android Oreo通知在状态栏中显示,但不在锁屏和点通知中显示,可以使用以下代码示例:
// 创建通知渠道
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
String channelId = "channel_id";
CharSequence channelName = "Channel Name";
int importance = NotificationManager.IMPORTANCE_HIGH;
NotificationChannel notificationChannel = new NotificationChannel(channelId, channelName, importance);
notificationChannel.enableLights(true);
notificationChannel.setLightColor(Color.RED);
notificationChannel.enableVibration(true);
notificationChannel.setLockscreenVisibility(Notification.VISIBILITY_SECRET);
NotificationManager notificationManager = getSystemService(NotificationManager.class);
notificationManager.createNotificationChannel(notificationChannel);
}
// 构建通知
NotificationCompat.Builder builder = new NotificationCompat.Builder(this, "channel_id")
.setSmallIcon(R.drawable.ic_notification)
.setContentTitle("标题")
.setContentText("内容")
.setPriority(NotificationCompat.PRIORITY_HIGH)
.setVisibility(NotificationCompat.VISIBILITY_SECRET)
.setAutoCancel(true);
// 发送通知
NotificationManagerCompat notificationManager = NotificationManagerCompat.from(this);
notificationManager.notify(notificationId, builder.build());
上述代码首先创建了一个通知渠道,并设置了锁屏可见性为VISIBILITY_SECRET
,然后使用NotificationCompat.Builder
构建通知,并将其锁屏可见性设置为VISIBILITY_SECRET
。最后,使用NotificationManagerCompat
发送通知。
这样设置后,通知将在状态栏中显示,但在锁屏和点通知中将不会显示。请注意,上述代码中的channel_id
需要与通知渠道的ID相匹配。
