的R.java文件不能与UI元素的ID更新 [英] R.java file not updating with UI element's id

问题描述

我加了一些UI元素的main.xml中的文件在res \布局文件夹，当我试图通过电话访问它们， R.layout.my_uielement ，我创建的UI元素是不存在的。甚至当我与UI元素添加一个新的XML文件，它仍然无法在 R.layout 类出现。我已经检查了他们的ID，他们有正确的格式（我认为）：机器人：ID =@ + ID / my_button。可能是什么问题？我需要首先编译code？
更新：
我已经尝试过 ADB杀死服务器然后亚行启动服务器。它似乎并没有帮助。我也曾尝试 R.id.my_uielement ，它没有任何注册。

I added some UI elements to the main.xml file in the res\layout folder and when I try to access them through the call, R.layout.my_uielement, the UI element that I created is not there. Even when I add a new xml file with UI elements, it still doesn't show up in the R.layout class. I have made checked the ids on them and they have the correct format (I think): android:id="@+id/my_button". What could be the problem? Do I need to compile the code first?
UPDATE:
I have already tried adb kill-server then adb start-server. It doesn't seem to help. I have also tried R.id.my_uielement, it doesn't register either.

推荐答案

这可能不是你的情况，但有时当我使用的东西从android.R包（默认的Andr​​oid资源），我在我的课用它参照从我自己的资源包任何事情之前，Eclipse中添加进口android.R;我进口语句。这将与含蓄看在你的包资源的默认行为发生冲突。

This may not be the case for you, but sometimes when I use something from the android.R package (default android resources) and I use it in my class before making reference to anything from my own resource package, Eclipse adds the import android.R; statement in my imports. This will conflict with the default behavior of implicitly looking in your package's resources.

检查import语句进口Android.R; 。如果它的存在，将其删除。而且，如果你使用的是从android.R什么，完全限定它，当你在code使用它。

Check your import statements for import Android.R;. If it's there, remove it. And, if you're using anything from android.R, fully qualify it when you use it in code.
