两个答案的组合。还输出一个方法名:

Class thisClass = new Object(){}.getClass();
String className = thisClass.getEnclosingClass().getSimpleName();
String methodName = thisClass.getEnclosingMethod().getName();
Log.d("app", className + ":" + methodName);

“1美元”不是“无用的废话”。如果您的类是匿名的，则会追加一个数字。

如果你不想要类本身，而是声明类，那么你可以使用getEnclosingClass()。例如:

Class<?> enclosingClass = getClass().getEnclosingClass();
if (enclosingClass != null) {
  System.out.println(enclosingClass.getName());
} else {
  System.out.println(getClass().getName());
}

你可以把它移动到一些静态工具方法中。

但请注意，这不是当前的类名。匿名类与它的外围类不同。内部类的情况也类似。

你可以像这样使用this.getClass().getSimpleName():

import java.lang.reflect.Field;

public class Test {

    int x;
    int y;  

    public String getClassName() {

        String className = this.getClass().getSimpleName(); 
        System.out.println("Name:" + className);
        return className;
    }

    public Field[] getAttributes() {

        Field[] attributes = this.getClass().getDeclaredFields();   
        for(int i = 0; i < attributes.length; i++) {
            System.out.println("Declared Fields" + attributes[i]);    
        }

        return attributes;
    }

    public static void main(String args[]) {

        Test t = new Test();
        t.getClassName();
        t.getAttributes();
    }
}

在您的示例中，这可能引用一个匿名类实例。Java通过在外围类的名称后面附加一个$number来为这些类命名。

我发现这适用于我的代码，但是我的代码是在for循环中从数组中获取类。

String className="";

className = list[i].getClass().getCanonicalName();

System.out.print(className); //Use this to test it works

反射api

There are several Reflection APIs which return classes but these may only be accessed if a Class has already been obtained either directly or indirectly. Class.getSuperclass() Returns the super class for the given class. Class c = javax.swing.JButton.class.getSuperclass(); The super class of javax.swing.JButton is javax.swing.AbstractButton. Class.getClasses() Returns all the public classes, interfaces, and enums that are members of the class including inherited members. Class<?>[] c = Character.class.getClasses(); Character contains two member classes Character.Subset and Character.UnicodeBlock. Class.getDeclaredClasses() Returns all of the classes interfaces, and enums that are explicitly declared in this class. Class<?>[] c = Character.class.getDeclaredClasses(); Character contains two public member classes Character.Subset and Character.UnicodeBlock and one private class Character.CharacterCache. Class.getDeclaringClass() java.lang.reflect.Field.getDeclaringClass() java.lang.reflect.Method.getDeclaringClass() java.lang.reflect.Constructor.getDeclaringClass() Returns the Class in which these members were declared. Anonymous Class Declarations will not have a declaring class but will have an enclosing class. import java.lang.reflect.Field; Field f = System.class.getField("out"); Class c = f.getDeclaringClass(); The field out is declared in System. public class MyClass { static Object o = new Object() { public void m() {} }; static Class<c> = o.getClass().getEnclosingClass(); } The declaring class of the anonymous class defined by o is null. Class.getEnclosingClass() Returns the immediately enclosing class of the class. Class c = Thread.State.class().getEnclosingClass(); The enclosing class of the enum Thread.State is Thread. public class MyClass { static Object o = new Object() { public void m() {} }; static Class<c> = o.getClass().getEnclosingClass(); } The anonymous class defined by o is enclosed by MyClass.
