我目前正在开发一个项目,我将ListView的适配器从ArrayAdapter更新为Custom CursorAdapter。
我有意删除了R.java,在将新的R.java
插入<string></string>
文件后重新生成res/string.xml
文件,因为它没有自动重新生成。该文件未生成。
我继续调试,并运行Project->Clean...
以尝试重新生成R.java
文件。这也不起作用。
在检查StackOverflow之后,我还尝试更改AndroidManifest.xml中的版本,希望重新生成该文件。这也行不通。我已经尝试了一些其他的黑客,希望Eclipse可以重新生成文件。没有运气。
有没有人有任何想法?我的时间紧迫,这真的让我退缩了。
以下是问题出现时我正在处理的文件:

我有解决方案,希望这会对你有所帮助。 !!
例如,如果您选择2.2作为构建目标,则选择您拥有的最大值。 (如4.4)
如果您选择4.4,则选择4.3作为目标。
谢谢。

这通常是因为您的XML或资源文件名中存在某个问题。 尝试重新启动Eclipse,如果它仍然没有指出问题所在,请尝试在发生此问题之前将您对XML文件所做的最后更改重新执行。您会在某处发现某种语法错误或拼写错误或无效的文件名。修复它,然后再次清洁。

如果你在Eclipse上打开问题视图(窗口 - &gt;显示视图 - &gt;问题)并在资源或清单中查找错误
答案 3 :(得分:0)
尝试重新启动eclipse,有时它可以解决问题。检查您是否使用jdk 7,它只需要jdk 6.
