我看着另一SO後（其中建議刪除繪製-MDPI到繪製文件夾），這並沒有幫助。

什麼是瘋狂的是在我的R.java沒有用於0x7f020056或0x7f020058沒有資源ID ...

克里斯。

Answer 1

據我所知，你不能有一個可繪製，MDPI文件夾，如果你正在建設1.5。所有屏幕尺寸相關的資源文件夾修飾符都是在android 1.6（這是支持多種屏幕尺寸的SDK的第一個版本）中引入的。除非你有一個特定的原因，否則我會建議你的應用程序至少構建SDK版本1.6。有太多不同屏幕尺寸的設備太多，使得用1.5製造的東西看起來不錯。如果你必須在1.5使你的項目，那麼你可能只需要擺脫與屏幕尺寸的修飾，所以任何文件夾：「繪製-MDPI」，「繪製 - 華電國際」，「繪製-LDPI」都需要離開，你應該只有「繪製」
