的问题是，你想在你的片段的sidebar_items数组的初始化获取资源：

private String[] sidebar_items = { 
    getString(R.string.title_drawer1), getString(R.string.title_drawer2), 
    getString(R.string.title_drawer3), getString(R.string.title_drawer4)};

对getString的调用要求片段已经连接到活动。然而，直到后期才会发生。当你访问数组

转换成sidebar_items一个int数组，像sidebar_images_on和调用的getString：

你有两个选择。
覆盖片段中的附件（活动），并在那里初始化sidebar_items 。
