Java Android RecyclerView固定页脚
过去几天，我一直在为我的recyclerview开发固定页脚，但到目前为止，我没有得到我预期的结果。我已经查看了现有的问题，但得到的结果与以前相同。似乎我仍然漏掉了一点，但我无法理解。。。因此，我在等待你的建议。谢谢 我希望页脚部分在recyclerview的底部保持粘性 draweradopter.javaJava Android RecyclerView固定页脚,java,android,android-recyclerview,footer,drawerlayout,Java,Android,Android Recyclerview,Footer,Drawerlayout,过去几天，我一直在为我的recyclerview开发固定页脚，但到目前为止，我没有得到我预期的结果。我已经查看了现有的问题，但得到的结果与以前相同。似乎我仍然漏掉了一点，但我无法理解。。。因此，我在等待你的建议。谢谢 我希望页脚部分在recyclerview的底部保持粘性 draweradopter.java public class DrawerAdapter extends RecyclerView.Adapter<DrawerAdapter.DrawerViewHolder>
