我在设备上完美地获得了notification。但它没有打开提到的Activity。在日志中，它会打印上述activity的日志，但会打开MainActivity。已经参考了Android docs中的代码，并根据此处https://stackoverflow.com/a/20744397/1928265的答案更改为代码。但仍然无法正常工作。
private void sendNotification(String title, String body) {
mNotificationManager = (NotificationManager)
this.getSystemService(Context.NOTIFICATION_SERVICE);
Intent resultIntent = new Intent(this, NotificationCenterActivity.class);
TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
stackBuilder.addParentStack(NotificationCenterActivity.class);
stackBuilder.addNextIntent(resultIntent);
PendingIntent resultPendingIntent =
stackBuilder.getPendingIntent(
0,
PendingIntent.FLAG_UPDATE_CURRENT | PendingIntent.FLAG_ONE_SHOT
);
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_launcher)
.setColor(16734816)
.setContentTitle(title)
.setStyle(new NotificationCompat.BigTextStyle()
.bigText(body))
.setDefaults(NotificationCompat.DEFAULT_ALL)
.setContentText(body);
mBuilder.setAutoCancel(true);
mBuilder.setContentIntent(resultPendingIntent);
mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
}

像这样使用
Random random = new Random();
int mid = random.nextInt(9999 - 1000) + 1000;
Intent notificationIntent = new Intent(context, landingactivity.class);
PendingIntent intent = PendingIntent.getActivity(context, mid, notificationIntent, PendingIntent.FLAG_ONE_SHOT);
Notification.Builder notification = new Notification.Builder(context)
.setContentTitle(title)
.setContentText(message)
.setAutoCancel(true)
.setLargeIcon(largeicon)
.setSmallIcon(R.drawable.smallicon_push)
.setTicker(message);
NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
notification.setContentIntent(intent);
mNotificationManager.notify(mid, notification.build());
mid 是用于标识通知的随机数。它应该是收到的所有通知的唯一。

可能有任何问题。我遇到了同样的问题。 试试这些步骤吧。很高兴，如果有效。
@Override
public void start(Stage primaryStage) {
StackPane root = new StackPane();
Pane pane = new Pane();
Circle circle = new Circle(100,100,100);
enableDragging(circle);
pane.getChildren().addAll(circle);
root.getChildren().addAll(pane);
circle.setOnDragOver(new EventHandler <DragEvent>() {
@Override
public void handle(DragEvent event) {
/* data is dragged over the target */
System.out.println("onDragOver");
Dragboard db = event.getDragboard();
if(db.hasFiles()){
event.acceptTransferModes(TransferMode.ANY);
}
event.consume();
}
});
circle.setOnDragDropped(new EventHandler <DragEvent>() {
@Override
public void handle(DragEvent event) {
/* data dropped */
System.out.println("onDragDropped");
Dragboard db = event.getDragboard();
if(db.hasFiles()){
for(File file:db.getFiles()){
//String absolutePath = file.getAbsolutePath();
String absolutePath = file.toURI().toString();
Image dbimage = new Image(absolutePath);
ImageView dbImageView = new ImageView();
dbImageView.setImage(dbimage);
circle.setFill(new ImagePattern(dbimage, 0, 0, 1, 1, true));
}
event.setDropCompleted(true);
}else{
event.setDropCompleted(false);
}
event.consume();
}
});
Scene scene = new Scene(root, 300, 300);
primaryStage.setTitle("Drag and Drop Image from Pc into Circle");
primaryStage.setScene(scene);
primaryStage.show();
}
private void enableDragging(Node node) {
final ObjectProperty<Point2D> mouseAnchor = new SimpleObjectProperty<>();
node.setOnMousePressed( event -> mouseAnchor.set(new Point2D(event.getSceneX(), event.getSceneY())));
node.setOnMouseDragged( event -> {
double deltaX = event.getSceneX() - mouseAnchor.get().getX();
double deltaY = event.getSceneY() - mouseAnchor.get().getY();
node.relocate(node.getLayoutX()+deltaX, node.getLayoutY()+deltaY);
mouseAnchor.set(new Point2D(event.getSceneX(), event.getSceneY()));;
});
}
public static void main(String[] args) {
launch(args);
}
}
。android:exported="true"
并在活动清单中设置PendingIntent.getActivity(context, 0, notificationIntent, Intent.FLAG_ONE_SHOT);。android:launchMode="singleInstance"
