这是我的通知代码。我已经尝试过NotificationCompat.VISIBILITY_PUBLIC或public void createNotification(String title,String body) {
String name = "my_package_channel";
String id = "my_package_channel_1"; // The user-visible name of the channel.
String description = "my_package_first_channel"; // The user-visible description of the channel.
Intent intent;
PendingIntent pendingIntent;
NotificationCompat.Builder builder;
if (Build.VERSION.SDK_INT >=26) {
int importance = NotificationManager.IMPORTANCE_HIGH;
NotificationChannel mChannel = notifManager.getNotificationChannel(id);
if (mChannel == null) {
mChannel = new NotificationChannel(id, name, importance);
mChannel.setDescription(description);
mChannel.setLightColor(Color.GREEN);
mChannel.setLockscreenVisibility(NotificationCompat.VISIBILITY_PUBLIC);
notifManager.createNotificationChannel(mChannel);
}
builder = new NotificationCompat.Builder(this, id);
intent = new Intent(this, MainActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
pendingIntent = PendingIntent.getActivity(this, 0, intent, 0);
builder.setContentTitle(title) // required
.setSmallIcon(R.drawable.sslogo) // required
.setContentText(body)//(this.getString(R.string.app_name)) // required
.setDefaults(Notification.DEFAULT_ALL)
.setContentIntent(pendingIntent)
.setVisibility(NotificationCompat.VISIBILITY_PUBLIC);
} else {
builder = new NotificationCompat.Builder(this);
intent = new Intent(this, MainActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
pendingIntent = PendingIntent.getActivity(this, 0, intent, 0);
builder.setContentTitle(title)
.setSmallIcon(R.drawable.sslogo) // required
.setContentText(body) // required
.setDefaults(Notification.DEFAULT_ALL)
.setContentIntent(pendingIntent)
.setPriority(Notification.PRIORITY_HIGH);
}
Notification notification = builder.build();
notifManager.notify(NOTIFY_ID, notification);
}
但是锁屏上没有任何反应。尽管在应用程序设置中，我允许锁定屏幕显示。
