Cannot set item click listener, Cannot set menu creator ,setAdapter has already been called

其实这两个错误一样的：

错误日志：

我这里是recyclerview嵌套recyclerview 报的错，大概的字面意思就是监听的方法不能再setadpter之前调用。

需要把监听方法放在setadpter之前就好了。

但我这里不同的是，我已经放在之前了，还是报错了。也郁闷了一会儿，无论放在那里都是报错。就想了一些方法，解决了问题，但是很鸡肋，没有使用，因为这里使用的是

SwipeRecyclerView 需要侧滑

 /*** Set to create menu listener.*/public void setSwipeMenuCreator(SwipeMenuCreator menuCreator) {if (menuCreator == null) return;checkAdapterExist("Cannot set menu creator, setAdapter has already been called.");this.mSwipeMenuCreator = menuCreator;}

这里会检查适配器，看到这里报错的信息是一样的，继续走

/*** Check the Adapter and throw an exception if it already exists.*/private void checkAdapterExist(String message) {if (mAdapterWrapper != null) throw new IllegalStateException(message);}

看到这里会应该有点明白，如果这个适配器不是null的话就报上面的错误！因为我这样操作报错的，在当前页面没有错误，而是点击一个item之后进入另一个页面，返回来的时候报错，断点查看，会继续调用

onBindViewHolder方法，里面就是嵌套的recyclerview，因为第一次加载的时候，就已经设置了嵌套的recyclerview适配器，这里进来的话就出现，这个嵌套的recycler已经有的，就报错了。

解决方法：

holder.recyc_list.setAdapter(null);holder.recyc_list.setSwipeMenuCreator(swipeMenuCreator);holder.recyc_list.setLayoutManager(layoutManager);

在之前把适配器置null就好了！
