让我开始说我是全新的
Android编程.我正在使用Pragmatic的Hello Android书(第3版).我正在研究流行的数独游戏示例,在将要放置在main.xml文件中的代码复制代码之后,我收到以下错误：
error: Error: No resource found that matches the given name (at 'background' with value '@color/background') . error: Error: No resource found that matches the given name (at 'text' with value '@string/main_title'). error: Error: No resource found that matches the given name (at 'text' with value '@string/continue_label'). error: Error: No resource found that matches the given name (at 'text' with value '@string/new_game_label'). error: Error: No resource found that matches the given name (at 'text' with value '@string/about_label'). error: Error: No resource found that matches the given name (at 'text' with value '@string/exit_label').
他们可能都是相关的,但在进行一些搜索之后,我不知道是什么问题.有什么建议么？
