如何摆脱警告：使用'$'而不是'。'对于Eclipse中的内部类 [英] How to get rid of the warning: Use '$' instead of '.' for inner classes in Eclipse

问题描述

我是Android开发的新手。在我将eclipse和Android SDK更新到最新版本后，我收到了警告：

I am new to Android development. After I updated my eclipse and Android SDK to the newest version, I got an warning:

Use '$' instead of '.' for inner classes (or use only lowercase letters in package names)   AndroidManifest.xml

我找到了一些信息在此链接。

I Found some information on this link.

"When you reference an inner class in a manifest file, you must use '$' instead of '.' " +
    "as the separator character, e.g. Outer$Inner instead of Outer.Inner.\n" +
    "\n" +
    "(If you get this warning for a class which is not actually an inner class, it's " +
    "because you are using uppercase characters in your package name, which is not " +
    "conventional.)"

我相信我在中使用了大写字符子包名称如 com.abc.app.Promotion 。

I believe that I used uppercase characters in sub package name like com.abc.app.Promotion.

问题是：什么是最好的方法在manifest.xml中摆脱这个警告？它仍然可以构建和运行，但我发现它很烦人。

The question is: What is the best way to get rid of this warning in the manifest.xml? It still can build and run but I find it so annoying.

我尝试使用重构来重命名包并修改了manifest.xml android： name =com.abc.app.promotion.Promotion但收到此错误：

I tried using refactor to rename the package and modified the manifest.xml android:name="com.abc.app.promotion.Promotion" but got this error:

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.abc.app/com.abc.app.TabView}: android.content.ActivityNotFoundException: Unable to find explicit activity class {com.abc.app/com.abc.app.promotion.Promotion}; have you declared this activity in your AndroidManifest.xml?

感谢您的帮助！

编辑：
原始manifest.xml

original manifest.xml

<activity android:name=".Promotion.Promotion" ></activity>

更新manifest.xml

updated manifest.xml

<activity android:name="promotion.Promotion" ></activity>

推荐答案

如果您收到此类警告实际上是一个内部类，这是因为你在包名中使用了大写字符，这不是传统的。

If you get this warning for a class which is not actually an inner class, it's because you are using uppercase characters in your package name, which is not conventional.

我还试图只改变包名的第一个字母为小写，警告消失。

I tried also to change only the first letter of the package name to be lower case, the warning disappeared.
