問題似乎是您要轉換drawerSelection為小寫字母。在R.java文件中很明顯，標識符的大小寫得以保留。嘗試致電：

int panelId = this.getResources().getIdentifier(drawerSelection,'id',getActivity().getPackageName());解決方法

如何從R.獲取ID的int id值？當我使用getIdentifier它的正好回報0。

int i = getArguments().getInt(SELECTION_NUMBER); String drawerSelection = getResources().getStringArray(R.array.drawerSelection_array)[i];int panelId = this.getResources().getIdentifier(drawerSelection.toLowerCase(),'id',getActivity().getPackageName());
