我正在尝试更改源的背景颜色，但java给出了内部致命错误发生的消息。你能告诉我我做错了吗？

许多示例使用此模式启动Swing应用程序。你可能想尝试一下。完整的目的是在Swing Thread中创建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：仔细查看问题后。您无法在Android / Dalvik平台上运行Swing。正如其他人评论的那样，如果在Sun JVM上运行它可以正常运行，您似乎在Android模拟器下运行它。那样不行。

如果您尝试在Android上运行此代码，请更新您的代码以包含Android。
