Delphi Java Bridge - 如何实例化 class 并在其上调用方法
Delphi Java Bridge - how to instance a class and call a method on it
我正尝试在我的 Delphi 项目中为 Android 使用 .jar 文件。遗憾的是，网上并没有资料说清楚这一点。
我按照 Embarcadero 在他们关于使用 Java2OP 的文档中所写的那样创建了 Bridge，并且我得到了 .pas 文件。我只想知道，如何使用界面JPrintUtilClass？我不知道这个文件是如何工作的，也不知道如何使用它。
这是 .pas 文件：
unit SdkPrint;
interface
uses
Androidapi.JNIBridge,
Androidapi.JNI.Bluetooth,
Androidapi.JNI.GraphicsContentViewText,
Androidapi.JNI.JavaTypes;

JPrintUtilClass接口是用来表示JavaPrintUtilclass的静态methods/properties，而JPrintUtil接口是意在表示非静态实例 methods/properties。您需要使用生成的 TJPrintUtil Delphi 包装器 class 的 JavaClass 属性 才能访问 Java PrintUtilclass，例如：
uses
SdkPrint;
TJPrintUtil.JavaClass.useSomeMemberHere;
...
根据您最近的评论，您从 SDK 文档中提供的示例的 正确 翻译在 Delphi:
中看起来像这样
uses
..., SdkPrint;
var
pUtil: JPrintUtil;
begin
try
pUtil := TJPrintUtil.JavaClass.getClient;
pUtil.printState;
pUtil.printAlignment(TJALIGN_MODE.JavaClass.ALIGN_LEFT);
pUtil.printTextBold(false);
pUtil.printTwoColumn(StringToJString('Time: '), StringToJString('2021-05-09 15:50:41'));
pUtil.printTwoColumn(StringToJString('order number:'), StringToJString('1'));
pUtil.printText(StringToJString('unit price'));
pUtil.printThreeColumn(StringToJString('iphoneXII'), StringToJString('1'), StringToJString('4999.00'));
pUtil.printThreeColumn(StringToJString('MAC PRO'), StringToJString('1'), StringToJString('4999.00'));
pUtil.printTwoColumn(StringToJString('order amount:'), StringToJString('9998.00'));
pUtil.printEndNumber;
except
end;
end;
但是，这在您的情况下不起作用，因为这些 PrintUtil 方法中的大多数都是非静态实例方法，但是 Java2OP 生成的 Delphi 代码您提供的是将它们全部视为静态 class 方法。这意味着 Java2OP 没有正确导入 JAR。这实际上是一个已知问题，请参阅以下错误报告：
RSP-15473: Java2Op emits erroneous code
RSP-21462: Java2OP outputting Class declarations instead of procedures
RSP-24029: Regression in Java2OP so that instance methods are treated as class methods
因此，您将不得不手动更正生成的代码中的错误，以便从 JPrintUtilClass 接口中移动 仅 非静态实例 methods/properties到 JPrintUtil 接口（并且可能对同一单元中的许多其他接口执行相同的操作）。那么上面的代码应该可以工作了。
我正尝试在我的 Delphi 项目中为 Android 使用 .jar 文件。遗憾的是，网上并没有资料说清楚这一点。
我按照 Embarcadero 在他们关于使用 Java2OP 的文档中所写的那样创建了 Bridge，并且我得到了 .pas 文件。我只想知道，如何使用界面JPrintUtilClass？我不知道这个文件是如何工作的，也不知道如何使用它。
这是 .pas 文件：

JPrintUtilClass接口是用来表示JavaPrintUtilclass的静态methods/properties，而JPrintUtil接口是意在表示非静态实例 methods/properties。您需要使用生成的 TJPrintUtil Delphi 包装器 class 的 JavaClass 属性 才能访问 Java PrintUtilclass，例如：
uses
SdkPrint;
TJPrintUtil.JavaClass.useSomeMemberHere;
...
根据您最近的评论，您从 SDK 文档中提供的示例的 正确 翻译在 Delphi:
中看起来像这样uses
..., SdkPrint;
var
pUtil: JPrintUtil;
begin
try
pUtil := TJPrintUtil.JavaClass.getClient;
pUtil.printState;
pUtil.printAlignment(TJALIGN_MODE.JavaClass.ALIGN_LEFT);
pUtil.printTextBold(false);
pUtil.printTwoColumn(StringToJString('Time: '), StringToJString('2021-05-09 15:50:41'));
pUtil.printTwoColumn(StringToJString('order number:'), StringToJString('1'));
pUtil.printText(StringToJString('unit price'));
pUtil.printThreeColumn(StringToJString('iphoneXII'), StringToJString('1'), StringToJString('4999.00'));
pUtil.printThreeColumn(StringToJString('MAC PRO'), StringToJString('1'), StringToJString('4999.00'));
pUtil.printTwoColumn(StringToJString('order amount:'), StringToJString('9998.00'));
pUtil.printEndNumber;
except
end;
end;
但是，这在您的情况下不起作用，因为这些 PrintUtil 方法中的大多数都是非静态实例方法，但是 Java2OP 生成的 Delphi 代码您提供的是将它们全部视为静态 class 方法。这意味着 Java2OP 没有正确导入 JAR。这实际上是一个已知问题，请参阅以下错误报告：
RSP-15473: Java2Op emits erroneous code
RSP-21462: Java2OP outputting Class declarations instead of procedures
RSP-24029: Regression in Java2OP so that instance methods are treated as class methods
因此，您将不得不手动更正生成的代码中的错误，以便从 JPrintUtilClass 接口中移动 仅 非静态实例 methods/properties到 JPrintUtil 接口（并且可能对同一单元中的许多其他接口执行相同的操作）。那么上面的代码应该可以工作了。
