Wie kleine Symbolbild in Benachrichtigung auf Android-Gerät mit DELPHI ändern

Question

Gibt es eine Möglichkeit, das kleine Symbolbild (standardmäßig verwendete Anwendungssymbol) in der Benachrichtigung in der Android-Anwendung mit Delphi zu ändern?

Der üblicher Weg, um leicht eine Benachrichtigung zu erstellen ist:

var 
    aNotification: TNotification; 
begin 
    aNotification:= aNotificationCenter.CreateNotification; 
    try 
    aNotification.Name:= 'Notification Name'; 
    aNotification.Title:= 'Notification Title'; 
    aNotification.AlertBody:= 'Notification Alert Body'; 
    aNotification.EnableSound:= False; 
    aWorkNotification.Number:= 1; 
    aNotificationCenter.PresentNotification(aNotification); 
    finally 
    aNotification.Free; 
    end; 
end; 

Ich kenne Lösung für Java, aber ich weiß nicht, wie das gleiche in Delphi programmiert.

Empfehlen Sie mir jemanden?

Answer 1

Bereiten Sie zuerst das Symbol im PNG-Format (16 x 16, z. B. ic_test) vor. Speichern Sie die png Symbol, um das Deployment auf diese Verzeichnisse mit:

res\drawable-ldpi\ 
res\drawable-mdpi\ 
res\drawable-hdpi\ 
res\drawable-xhdpi\ 
res\drawable-xxhdpi\ 

Verwenden Sie dann den folgenden Code:

. 
. 
var 
    Ntf: JNotification; 
    ntfBuilder: JNotificationCompat_Builder; 
    ntfManager: JNotificationManager; 
. 
. 
    ntfBuilder:= TJNotificationCompat_Builder.JavaClass.init(TAndroidHelper.Context); 
    ntfBuilder.setSmallIcon(TAndroidHelper.Context.getResources.getIdentifier(StringToJString('ic_test'), StringToJString('drawable'), TAndroidHelper.Context.getPackageName)); 
    ntfBuilder.setContentTitle(StrToJCharSequence('Content Title')); 
    ntfBuilder.setContentText(StrToJCharSequence('Content Test')); 
    ntfBuilder.setAutoCancel(True); 

    Ntf:= ntfBuilder.build; 

    ntfManager:= TJNotificationManager.Wrap((TAndroidHelper.Context.getSystemService(TJContext.JavaClass.NOTIFICATION_SERVICE) as ILocalObject).GetObjectID); 
    ntfManager.notify(1, Ntf); 
. 
. 

Wenn Sie integrierte System Symbole verwenden möchten, verwenden Sie diese

mit dem folgenden Code (z. B. für das Android-Äquivalent von R.drawable.ic _menu_send):

ntfBuilder.setSmallIcon(r_drawable_ic_menu_send);
