java - 通过反射实例化静态抽象类

Question

public class FingerprintManager {

     * @hide
     */
   // this class is hidden 
    public static abstract class EnrollmentCallback {

        public void onEnrollmentError(int errMsgId, CharSequence errString) { }


        public void onEnrollmentHelp(int helpMsgId, CharSequence helpString) { }


        public void onEnrollmentProgress(int remaining) { }
    };
}

EnrollmentCallback 类是隐藏的。有没有办法通过反射实例化 EnrollmentCallback 类，相当于:

EnrollmentCallback callbackObject = new EnrollmentCallback ()
{
        public void onEnrollmentError(int errMsgId, CharSequence errString) { }


        public void onEnrollmentHelp(int helpMsgId, CharSequence helpString) { }


        public void onEnrollmentProgress(int remaining) { }
};

Answer 1

没有。使用字节码操作库(如 ASM )也许可以做到这一点，但如果不扩展它并实现任何缺失的(abstract) 方法。 Java 反射无法做到这一点。
