使用以下代码:

    StackTraceElement[] stacktrace = Thread.currentThread().getStackTrace();
    StackTraceElement e = stacktrace[1];//coz 0th will be getStackTrace so 1st
    String methodName = e.getMethodName();
    System.out.println(methodName);

要获取调用当前方法的方法的名称，您可以使用:

new Exception("is not thrown").getStackTrace()[1].getMethodName()

这在我的MacBook和我的Android手机上都可以使用

我还试过:

Thread.currentThread().getStackTrace()[1]

但是Android会返回"getStackTrace" 我可以修复这个Android

Thread.currentThread().getStackTrace()[2]

但后来我在笔记本电脑上得到了错误的答案

这是对virgo47的答案(如上)的扩展。

它提供了一些静态方法来获取当前和调用类/方法名。

如果您想知道的方法名称是junit测试方法，那么您可以使用junit TestName规则:https://stackoverflow.com/a/1426730/3076107

我们使用这段代码来减少堆栈跟踪索引的潜在可变性-现在只需调用methodName util:

public class MethodNameTest {
    private static final int CLIENT_CODE_STACK_INDEX;

    static {
        // Finds out the index of "this code" in the returned stack trace - funny but it differs in JDK 1.5 and 1.6
        int i = 0;
        for (StackTraceElement ste : Thread.currentThread().getStackTrace()) {
            i++;
            if (ste.getClassName().equals(MethodNameTest.class.getName())) {
                break;
            }
        }
        CLIENT_CODE_STACK_INDEX = i;
    }

    public static void main(String[] args) {
        System.out.println("methodName() = " + methodName());
        System.out.println("CLIENT_CODE_STACK_INDEX = " + CLIENT_CODE_STACK_INDEX);
    }

    public static String methodName() {
        return Thread.currentThread().getStackTrace()[CLIENT_CODE_STACK_INDEX].getMethodName();
    }
}

似乎是过度设计了，但我们对JDK 1.5有一些固定的数字，当我们迁移到JDK 1.6时，它发生了变化，这有点令人惊讶。现在在Java 6/7中也是一样的，但你永远不会知道。它不能证明索引在运行时发生了变化——但希望HotSpot不会做得那么糟糕。: -)

Util.java:

public static String getCurrentClassAndMethodNames() {
    final StackTraceElement e = Thread.currentThread().getStackTrace()[2];
    final String s = e.getClassName();
    return s.substring(s.lastIndexOf('.') + 1, s.length()) + "." + e.getMethodName();
}

SomeClass.java:

public class SomeClass {
    public static void main(String[] args) {
        System.out.println(Util.getCurrentClassAndMethodNames()); // output: SomeClass.main
    }
}
