原文 2013-09-02 03:01:44 9 3 java/ android

I was doing some work on my app when I accidentally deleted the file R.java in the gen folder. 当我意外删除gen文件夹中的文件R.java时，我正在对我的应用程序进行一些工作。 Is there any way to get it back? 有什么办法找回它吗？ I need it because it is giving ever activity errors. 我需要它，因为它给活动带来了错误。 I tried copying my data into another application and that didn't work. 我尝试将数据复制到另一个应用程序中，但没有用。 I also checked my recycle bin and there was no file and cleaned. 我还检查了回收站，没有文件被清理。 Please help? 请帮忙？

3 个解决方案

Several ways to get out: 几种逃脱方式：

Simply modify(add a white space or so) in one of your resource files and save it, if the eclipse is enabled 'build automatically', the R.java will be re-generated again. 只需在您的一个资源文件中修改（添加空格左右）并将其保存，如果启用了“自动构建”蚀，则R.java将再次重新生成。
Go to project - clean project, clean your project and it will be re-generated when you run the project again 转到项目-清理项目，清理项目，当您再次运行项目时，它将重新生成

It is automatically generated file 它是自动生成的文件

Just clean and rebuild you project If there is no error{there must not any xml error which neither shown error nor let R.java build} then it will create your R.java file 只是清理并重建您的项目如果没有错误{没有任何xml错误，既没有显示错误，也没有让R.java建立}，那么它将创建您的R.java文件

again 再次

Every Successful build just re-create new R.java file 每个成功的构建都只是重新创建新的R.java文件

R.java is auto generated when you delete it, make sure the xml file has no error . 删除R.java是自动生成的，请确保xml文件没有错误。 If this is also not solving your problem the start doing your project from scratch no copy paste. 如果这也不能解决您的问题， 请从头开始做项目，不要复制粘贴。
