/mnt/wsl我有两种简单的方法，一种用于发送通知，另一种用于创建通知频道
一切对我来说似乎都不错，但是没有发送任何通知，我也想提及一下，同一频道创建了两次（我查看了应用的通知设置），尽管文档中提到了 private void sendNotif(String title , String text , int id) {
// Create an explicit intent for an Activity in your app
Intent intent = new Intent(this, MainActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
PendingIntent pendingIntent = PendingIntent.getActivity(this, id, intent, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder builder = new NotificationCompat.Builder(this, "mychannel")
.setSmallIcon(android.R.drawable.screen_background_light)
.setContentTitle(title)
.setContentText(text)
.setStyle(new NotificationCompat.BigTextStyle()
.bigText(text))
// Set the intent that will fire when the user taps the notification
.setContentIntent(pendingIntent)
.setChannelId("mychannel")
.setAutoCancel(true)
.setOngoing(false);
NotificationManagerCompat notificationManager = NotificationManagerCompat.from(this);
// notificationId is a unique int for each notification that you must define
notificationManager.notify(id , builder.build());
}
private void createNotificationChannel() {
// Create the NotificationChannel, but only on API 26+ because
// the NotificationChannel class is new and not in the support library
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
CharSequence name = "notif channel";
String description = "this is the main notif channel";
int importance = NotificationManager.IMPORTANCE_HIGH;
NotificationChannel channel = new NotificationChannel("mychannel", name, importance);
channel.setDescription(description);
// Register the channel with the system; you can't change the importance
// or other notification behaviors after this
NotificationManager notificationManager = getSystemService(NotificationManager.class);
notificationManager.createNotificationChannel(channel);
}
}
一次：
安全地重复调用此操作是因为创建了一个现有的 通知通道不执行任何操作。
但是它确实很明显
我正在使用android 10，这是我的build.gradle文件：
createNotificationChanne()预先感谢
答案 0 :(得分：0)
我已经尝试了您的代码，效果很好。我认为您可能忘记了在创建通知之前致电createNotificationChannel()。
private void sendNotif(String title , String text , int id) {
createNotificationChannel()
// create notification code goes here
}
