实际上，我不知道为什么会出现这个错误。

遵循代码，希望有对诊断有用的一切。

应用的结构是一个标准的Navigation Drawer Activity，里面有一个Fragment。 Fragment 有一个 RecyclerView。

使用的设备是Motorola XT1068(Android 6.0，API 23)。

更新

其中一个答案表明问题可能与 getAllItems() 有关。但调用的资源似乎已正确加载。

最佳答案

您的问题是资源(图像)的错误放置。 您使用 (API 23) 但 API 23 的资源为空，因为它们只有 API 24 及更高版本。

现在所有标记为 (v24) 的图像这意味着它们在 drawables-v24 中只是在 drawable 中移动

这会解决你的问题。
