Android RecyclerView LayoutManager异常 [英] Android RecyclerView LayoutManager Exception

问题描述

我遇到了新的Android Lollipop RecyclerView

它保持崩溃，但有以下例外:

Attempt to invoke virtual method 'void android.support.v7.widget.RecyclerView$LayoutManager.onMeasure(android.support.v7.widget.RecyclerView$Recycler, android.support.v7.widget.RecyclerView$State, int, int)' on a null object reference

完整的堆栈跟踪可以在这里找到

用于启动RecyclerView的代码与本教程几乎相同，但是由于某些原因，仍然会抱怨.任何帮助将不胜感激.

The code used to initiate the RecyclerView is the same mostly the same as the tutorial, however for some reason this still complains. Any help would be greatly appreciated.

可以在以下位置访问该代码:要点此处和布局:

The code can be accessed at: gist here and layout: this gist

views或objects都不是null

推荐答案

添加以下代码:

    LinearLayoutManager layoutManager = new LinearLayoutManager(getActivity());
    layoutManager.setOrientation(LinearLayoutManager.VERTICAL);
    recyclerView.setLayoutManager(layoutManager);

之前添加适配器:

recyclerView.setAdapter(adapter);
