等待你的帮助!!!谢谢!!!
答案 0 :(得分：0)
第一个异常会告诉您R文件中提到的但res文件夹中没有的资源。这意味着您应该清理并重建项目以重新生成R文件。希望这有点帮助。
答案 1 :(得分：0)
是的，首先要清理你的项目。此代码的for (i=0x7f020000 ;done&&i<0x7f020040;i++)部分也非常危险，因为您的资源ID将在每次构建后更改，并且在项目中添加另一个ID后，大多数情况下肯定会失败。
您可能还想重新考虑您的设计。为什么在ListView中使用按钮？您应该只放置图像并在Activity中实现onItemClickListener界面，并在用户单击ListView中的项目时拦截`onItemClick(...)方法。
