将项目导入 Eclipse 后出现“必须覆盖超类方法"错误 [英] 'Must Override a Superclass Method' Errors after importing a project into Eclipse
问题描述
任何时候我必须将我的项目重新导入到 Eclipse 中(如果我重新安装 Eclipse，或者更改了项目的位置)，几乎所有我覆盖的方法都没有正确格式化，从而导致错误:
Anytime I have to re-import my projects into Eclipse (if I reinstalled Eclipse, or changed the location of the projects), almost all of my overridden methods are not formatted correctly, causing the error:
该方法必须覆盖超类方法
The method must override a superclass method
值得一提的是，无论出于何种原因，这都是 Android 项目，方法参数值并不总是填充，所以我必须自己手动填充它们.例如:
It may be noteworthy to mention this is with Android projects for whatever reason, the method argument values are not always populated, so I have to manually populate them myself. For instance:
list.setOnCreateContextMenuListener(new OnCreateContextMenuListener() {
//These arguments have their correct names
public void onCreateContextMenu(ContextMenu menu, View v,
ContextMenuInfo menuInfo) {
}
});
最初会像这样填充:
list.setOnCreateContextMenuListener(new OnCreateContextMenuListener() {
//This methods arguments were not automatically provided
public void onCreateContextMenu(ContextMenu arg1, View arg2,
ContextMenuInfo arg3) {
}
});
奇怪的是，如果我删除我的代码，并让 Eclipse 自动重新创建该方法，它会使用我已经拥有的相同参数名称，所以我真的不知道问题出在哪里，否则它会自动格式化适合我的方法.
The odd thing is, if I remove my code, and have Eclipse automatically recreate the method, it uses the same argument names I already had, so I don't really know where the problem is, other then it auto-formatting the method for me.
不得不手动重新创建我所有被覆盖的方法，这变得非常痛苦.如果有人可以解释为什么会发生这种情况或如何解决它.我会很高兴.
This becomes quite a pain having to manually recreate ALL my overridden methods by hand. If anyone can explain why this happens or how to fix it. I would be very happy.
也许是因为我格式化方法的方式，这些方法在另一个方法的参数中?
Maybe it is due to the way I am formatting the methods, which are inside an argument of another method?
推荐答案
Eclipse 默认为 Java 1.5 并且您有实现接口方法的类(在 Java 1.6 中可以用 @Override 注释，但是在 Java 1.5 中只能应用于覆盖超类方法的方法).
Eclipse is defaulting to Java 1.5 and you have classes implementing interface methods (which in Java 1.6 can be annotated with @Override, but in Java 1.5 can only be applied to methods overriding a superclass method).
转到您的项目/IDE 首选项并将 Java 编译器级别设置为 1.6，并确保您选择 JRE 1.6 以从 Eclipse 执行您的程序.
Go to your project/IDE preferences and set the Java compiler level to 1.6 and also make sure you select JRE 1.6 to execute your program from Eclipse.
