Android中的RecyclerView空指针异常

Question

 Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'void android.support.v7.widget.RecyclerView.setLayoutManager(android.support.v7.widget.RecyclerView$LayoutManager)' on a null object reference

网上说是没有设置布局管理器，我设置了 还是报这个异常

  //设置RecyclerView的布局管理：
        LinearLayoutManager linearLayoutManager = new LinearLayoutManager(this,LinearLayoutManager.HORIZONTAL,false);
        //上面的属性为(this,orientation,reverseLayout)上面使用垂直属性
        mRecyclerView.setLayoutManager(linearLayoutManager);

Answer 1

mRecyclerView空指针，检查下是不是没绑定
