在代码很多的时候看log点进去看啊 log双击每一行 能进去的话 看看进去之后的那一行的上下左右 基本错误就在这了

对啊，我就是这样看的，跳到 recyclerView.setAdapter(mAdapter);一行崩溃的，实在不知道什么情况。

我觉得应该是找不到adapter吧 没有初始化 就是没有adapter=？？？？的语句

[蒲锦_up]

adapter 你确定初始化了？？

我已经蒙蔽。。。

[qq_29637837]

adapter代码贴出来呀，你log打印看看adapter里面是不是有数据

[jklwan]

findView()是什么时候执行的？，应该是控件初始化之前你就去设置数据了。
