解决方案
许多示例使用此模式启动Swing应用程序。你可能想尝试一下。整个目的是在Swing Thread中创建Swing组件。
public static void main（String [] args）{
//为事件调度线程安排作业：
//创建并显示此应用程序的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。您不能在Android / Dalvik平台上运行Swing。正如其他人已经评论的那样，如果在Sun JVM上运行，那么您似乎在Android模拟器下运行它。这是行不通的。
如果您尝试在Android上运行，请更新您的标签以包含Android。

解决方案
Many examples use this pattern for launching a Swing app. You might want to try it. The whole purpose is to create the Swing components inside the Swing Thread.
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();
}
});
}
EDIT: After looking through the question more carefully. You cannot run Swing on the Android/Dalvik platform. As other people have commented it works fine if running on a Sun JVM, You seem to be running it under the Android emulator. That will not work.
Please update your tags to include Android if you are trying to run this on Android.
