Android绑定使用EnumMethods.xml为接口定义Getter/Setter方法

我对EnumMethods.xml有问题。我将其用于一些接口，映射工作正常。但是，如果我有另一个扩展了原始接口的接口，则映射不起作用，我会得到以下错误：

“无法将类型'int'隐式转换为'MyEnum'。存在显式转换（是否缺少转换？）”

及

“无法将类型'MyEnum'隐式转换为'int'。存在显式转换（是否缺少转换？）”

有什么建议吗

映射如下所示：

<代码> > p>首先，让我们看一下<代码> API .xml <代码>定义<代码>核心.IVIEW  >：

<interface abstract="true" deprecated="not deprecated" final="false" name="IView" static="false" visibility="public">
<method abstract="true" deprecated="not deprecated" final="false" name="getVisibility" native="false" return="int" static="false" synchronized="false" visibility="public">
</method>
<method abstract="true" deprecated="not deprecated" final="false" name="setVisibility" native="false" return="void" static="false" synchronized="false" visibility="public">
<parameter name="p0" type="int">
</parameter>
</method>
</interface>

特别是在
n\u SetVisibility\u I
和
n\u GetVisibility
方法中。请尝试为另一个映射指定
jni接口，而不是
jni类
。它们都使用jni接口。刚刚更新了问题您是否为相关接口添加了一个额外的问题？是的，我为两个接口都添加了。我唯一没有提到的是，这些接口在不同的项目/libs中。如果您有绑定项目的副本，可以上传并附加到您的问题，我可以看一看。哦，我看到了那个参数，谢谢。但是现在出现了另一个警告：“[Method]void setVisibility（int p0）中的[Interface]dom.core.IView有‘unnamed’参数”这是因为p0吗？关于演员的，有没有办法忽略这个？我的意思是，在生成代码后手动进行强制转换就是pita。有没有办法解决这些强制转换问题？
