Attempt to invoke virtual method 'void android.app.ActionBar.setTitle的解决方法

在安卓4.4.2的关于蓝牙开发的一个sample BluetoothChat中,调试时,老是出错:Attempt to invoke virtual method 'void android.app.ActionBar.setTitle

上网查了一下,是这么说的:

     (http://www.tuicool.com/articles/IRzUR3M)

The LayoutManager is probably the most interesting part of theRecyclerView . This class is responsible for layouting all child views. There isone default implementation available: LinearLayoutManager which you can use for vertical as well as horizontal lists.

You have to set a LayoutManager for your RecyclerView otherwise you will see an exception at Runtime:

所以我就把源代码中的:

private final void setStatus(int resId)

private final void setStatus(CharSequence subTitle)

这两个方法注释掉,就可以正常运行了。
