如何使用 DELPHI 在 Android 设备上更改通知中的小图标图像
How to change small icon image in notification on Android device with DELPHI
有什么方法可以更改 Android 应用程序通知中的小图标图像（默认使用的应用程序图标）Delphi？
轻松创建通知的标准方法是：
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;
我知道 Java 的解决方案，但我不知道如何在 Delphi 中编写相同的程序。
有人告诉我吗？
首先，准备png格式的图标（16 x 16，命名如ic_test）。使用 Deployment 将 png 图标保存到这些目录：
res\drawable-ldpi\
res\drawable-mdpi\
res\drawable-hdpi\
res\drawable-xhdpi\
res\drawable-xxhdpi\
然后使用下面的代码：
.
.
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);
.
.

使用以下代码（例如，对于 android 相当于 R.drawable.ic _menu_send):
ntfBuilder.setSmallIcon(r_drawable_ic_menu_send);
因为它在 Android 11 和 Delphi 10.3 上对我不起作用，
我在 System.Notification 和 System.Android.Notification 文件中进行了更改；
（我将它们复制到我的路径并将它们添加到我的应用程序中所以原始文件没问题）
System.Notification 变化：
我向 TNotification 添加了一个新的 public 字段：
SmallIconID : Integer;
并且在构造函数中我用-1初始化；
SmallIconId := -1;
System.Android.Notification 变化：
函数中TNotificationCenterAndroid.CreateNativeNotification
我在 if TOSVersion.Check(5) 行之前添加了这段代码：
if ANotification.SmallIconID > -1 then
Builder := Builder.setSmallIcon(ANotification.SmallIconID);
现在我可以在我的应用程序中设置小图标，它也在 Android 11 上运行。
有什么方法可以更改 Android 应用程序通知中的小图标图像（默认使用的应用程序图标）Delphi？
轻松创建通知的标准方法是：
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;
我知道 Java 的解决方案，但我不知道如何在 Delphi 中编写相同的程序。
有人告诉我吗？
首先，准备png格式的图标（16 x 16，命名如ic_test）。使用 Deployment 将 png 图标保存到这些目录：
res\drawable-ldpi\
res\drawable-mdpi\
res\drawable-hdpi\
res\drawable-xhdpi\
res\drawable-xxhdpi\
然后使用下面的代码：
.
.
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);
.
.

使用以下代码（例如，对于 android 相当于 R.drawable.ic _menu_send):
ntfBuilder.setSmallIcon(r_drawable_ic_menu_send);
因为它在 Android 11 和 Delphi 10.3 上对我不起作用， 我在 System.Notification 和 System.Android.Notification 文件中进行了更改；
（我将它们复制到我的路径并将它们添加到我的应用程序中所以原始文件没问题）
System.Notification 变化：
我向 TNotification 添加了一个新的 public 字段：
SmallIconID : Integer;
并且在构造函数中我用-1初始化；
SmallIconId := -1;
System.Android.Notification 变化：
函数中TNotificationCenterAndroid.CreateNativeNotification 我在 if TOSVersion.Check(5) 行之前添加了这段代码：
if ANotification.SmallIconID > -1 then
Builder := Builder.setSmallIcon(ANotification.SmallIconID);
现在我可以在我的应用程序中设置小图标，它也在 Android 11 上运行。
