Start specific view of Gluon App from a notification

问题

I set up an alarm to show a corresponding Notification. The PendingIntent of the Notification is used to start the Gluon App main class. To show a View other than the homeView, I call switchView(otherView) in the postInit method. OtherView is shown, but without AppBar. While it's possible to make the AppBar appear, I wonder if this is the right approach.

@Override
public void postInit(Scene scene) {
    // additional setUp logic

    boolean showReadingView = (boolean) PlatformProvider.getPlatform().getLaunchIntentExtra("showReadingView", false);
    if (showReadingView) {
        switchView(READING_VIEW);
    }
}

回答1:

When triggering anything related to the JavaFX thread from another thread, we have to use Platform.runLater().

Yours is a clear case of this situation: the Android thread is calling some pending intent, and as a result, the app is started again.

This should be done:

@Override
public void postInit(Scene scene) {
    // additional setUp logic

    boolean showReadingView = (boolean) PlatformProvider.getPlatform().getLaunchIntentExtra("showReadingView", false);
    if (showReadingView) {
        Platform.runLater(() -> switchView(READING_VIEW));
    }
}
