许多示例使用此模式启动Swing应用程序。你可能想试试。整个目的是在Swing线程内创建Swing组件

public static void main(String[] args) {
    //Schedule a job for the event-dispatching thread:
    //creating and showing this application's GUI.
    javax.swing.SwingUtilities.invokeLater(new Runnable() {
        public void run() {
             JFrame frame = new ButtonFrame();
             frame.show(); 
        }
    });
}

编辑：在仔细阅读问题之后。您不能在Android/Dalvik平台上运行Swing。正如其他人所评论的，如果在Sun JVM上运行，它工作得很好，您似乎是在Android仿真器下运行它。那是行不通的

如果您试图在Android上运行此功能，请更新您的标签，使其包含Android。

适用于我使用最新JDK在Linux上的操作：显示一个带有灰色按钮的框架；单击按钮，它将变为黄色。没有错误。请发布您收到的确切异常消息。实际发布可编译代码+1。我希望这是正常的，而不是例外！错误报告文件中有任何信息吗？检查C:\Program Files（x86）\eclipse\android sdk windows\samples\android-8\Snake\hs\u err\u pid1156.log，并可能发布该日志以查看导致致命错误的原因。我想我没有编译代码。我正在使用eclipse，当我按下run时，它就不工作了。事实上，我经常遇到这个问题。我曾经使用过VisualStudio，我认为当您按下run按钮或“RunasJavaAppision”时也是如此。是否有合适的方法从EclipseIDE运行应用程序。好，但我无法运行我的程序。不知道它为什么会失败真的很烦人。

Java虚拟机：Java HotSpot（TM）64位服务器虚拟机

-这不能Dalvik，是吗？我用你的代码给出了同样的错误。我从命令行运行它。我用javac来编译它。要使用jvm，我应该怎么做？@Dave查看您的错误，我看到以下内容：VM参数：jvm参数：-Dfile.encoding=Cp1252-Xbootclasspath:C:\Program Files（x86）\eclipse\android sdk windows\platforms\android-8\android.jar java_命令：dalvik.system.TouchDexI实际上将我的代码复制到我桌面上的纯文本文件中，并使用命令行进行编译。当我编译它时，它是有效的。当我尝试运行它时，它会给我这个错误消息。线程“main”java.lang.nosuchMethodError中出现异常：main
