从接口继承的Delphi Android Java类

标签： java android delphi

我正在尝试在Delphi中实施最新版本的Google Play服务（15.01）。我将相关的库合并到一个jar文件中，并使用java2op提取了一个桥接文件。一切运行都非常顺利，直到我碰上了这个展示排行榜：

我上了这个课：

JRoomConfigClass = interface(JObjectClass)
['{88F39239-F51D-4BA0-8131-24EBF070A584}']
{class} function builder(P1: JRoomUpdateListener): JRoomConfig_Builder; 
cdecl; overload;
{class} function builder(P1: JRoomUpdateCallback): JRoomConfig_Builder; 
cdecl; overload;
{class} function createAutoMatchCriteria(P1: Integer; P2: Integer; P3: 
Int64): JBundle; cdecl;
end;

[JavaSignature('com/google/android/gms/games/multiplayer/realtime/
RoomConfig')]
JRoomConfig = interface(JObject)
['{EF764B81-BF25-490C-8562-D9DC6BB337AD}']
function getAutoMatchCriteria: JBundle; cdecl;
function getInvitationId: JString; cdecl;
function getInvitedPlayerIds: TJavaObjectArray<JString>; cdecl;
function getMessageReceivedListener: JRealTimeMessageReceivedListener; cdecl;
function getOnMessageReceivedListener: JOnRealTimeMessageReceivedListener; 
cdecl;
function getRoomStatusUpdateCallback: JRoomStatusUpdateCallback; cdecl;
function getRoomStatusUpdateListener: JRoomStatusUpdateListener; cdecl;
function getRoomUpdateCallback: JRoomUpdateCallback; cdecl;
function getRoomUpdateListener: JRoomUpdateListener; cdecl;
function getVariant: Integer; cdecl;
function zzch: Jrealtime_zzh; cdecl;
end;
TJRoomConfig = class(TJavaGenericImport<JRoomConfigClass, JRoomConfig>) end;

我将方法称为“生成器”：

rtmConfigBuilder := TJRoomConfig.JavaClass.builder(RoomUpdateCallback);

但是RoomUpdateCallback的定义如下：

JRoomUpdateCallbackClass = interface(JRoomUpdateListenerClass)
['{B7973699-780A-4D76-9585-D113DD245CC5}']
{class} function init: JRoomUpdateCallback; cdecl;
end;
[JavaSignature('com/google/android/gms/games/multiplayer/realtime/
RoomUpdateCallback')]

JRoomUpdateCallback = interface(JRoomUpdateListener)
['{0CA35AB2-8AA9-4604-909B-68DE93112867}']
procedure onJoinedRoom(P1: Integer; P2: JRoom); cdecl;
procedure onLeftRoom(P1: Integer; P2: JString); cdecl;
procedure onRoomConnected(P1: Integer; P2: JRoom); cdecl;
procedure onRoomCreated(P1: Integer; P2: JRoom); cdecl;
end;
TJRoomUpdateCallback = class(TJavaGenericImport<JRoomUpdateCallbackClass, 
JRoomUpdateCallback>) end;

所以，这不是一个接口，这意味着我不能使用通常的侦听器方法：

TRoomUpdateListener = class(TJavaLocal, JRoomUpdateCallback)
  procedure onJoinedRoom(P1: Integer; P2: JRoom); cdecl;
  procedure onLeftRoom(P1: Integer; P2: JString); cdecl;
  procedure onRoomConnected(P1: Integer; P2: JRoom); cdecl;
  procedure onRoomCreated(P1: Integer; P2: JRoom); cdecl;
 end;

但是JRoomUpdateCallback是作为接口的JRoomUpdateListener的后代：

JRoomUpdateListenerClass = interface(IJavaClass)
['{62795DB4-DDD0-48F2-AABA-644CC96D5E6E}']
end;

[JavaSignature('com/google/android/gms/games/multiplayer/realtime/
RoomUpdateListener')]
JRoomUpdateListener = interface(IJavaInstance)
['{236212AF-A72A-4DEC-BB73-E0B42E80F7A1}']
procedure onJoinedRoom(P1: Integer; P2: JRoom); cdecl;
procedure onLeftRoom(P1: Integer; P2: JString); cdecl;
procedure onRoomConnected(P1: Integer; P2: JRoom); cdecl;
procedure onRoomCreated(P1: Integer; P2: JRoom); cdecl;
end;
TJRoomUpdateListener = class(TJavaGenericImport<JRoomUpdateListenerClass, 
JRoomUpdateListener>) end;

我该如何实施？有可能吗？

没有办法解决。我必须编写一些Java代码。如果有人可以从中受益，这就是我放在Java库中的内容。
