Android Inflater崩溃

Question

我是新来的论坛，我相信我犯了一个很大的错误，我的代码（某处）。

我正在尝试构建一个android应用程序的第一次，没有经验的Java或应用程序创建之前，所以请裸露在我身边。

我的想法是创建词汇表应用程序，它已启动并正在运行，但是当我尝试添加微调器时，它崩溃了。现在我已经移除了Spinner，但该应用程序仍然崩溃。

05-21 10:51:29.970: E/AndroidRuntime(22736): android.view.InflateException: Couldn't resolve menu item onClick handler onLanguageButtonClick in class se.inceptive.irebglossary.MainActivity 
05-21 10:51:29.970: E/AndroidRuntime(22736): at se.inceptive.irebglossary.MainActivity.onCreateOptionsMenu(MainActivity.java:58) 

，这是发表在第58行：

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
// Inflate the menu; this adds items to the action bar if it is present. 
    getMenuInflater().inflate(R.menu.main, menu); 
    return true; 
} 

任何帮助是非常赞赏

你似乎已经指定其中一个菜单项的onClick处理程序（在th e XML）为onLanguageButtonClick，但您尚未在活动代码中提供onLanguageButtonClick的实施。
