我是来自 Java 背景的 Android 新手。如果这是一个非常简单的修复，请原谅。我在 java 中创建了一个机器模拟器，我想用一个简单的 UI 在 Android 上运行它。问题是当我这样做时它崩溃了

 public class UITerminal extends EditText implements Terminal

我也在课堂上试过这个

 Terminal terminal;
 public void init()
 {
      terminal = new Terminal()
      {
         //implemented methods
      }
 }

这两种解决方案在打开时都崩溃了。关于我应该如何做到这一点的任何建议？提前致谢。这是我的第一次安卓体验。

我点击该应用程序，它显示“不幸的是 MyTronEmulator 已停止工作”

除了将其添加为库之外，您还必须确保您的 IDE 正在导出 .jar 文件。否则假定它已经在手机/模拟器上。

在 Eclipse 中，您可以通过右键单击项目 -> 构建路径 -> 配置构建路径 -> 订购和导出 -> 检查库来确保完成此操作。

这是前一阵子，但我试图使用 Java 1.7 库。Android 只支持最高 1.6 我希望错误只是说:)
