defStyleAttr, defStyleRes);
properties.orientation = a.getInt(R.styleable.RecyclerView_android_orientation, VERTICAL);
properties.spanCount = a.getInt(R.styleable.RecyclerView_spanCount, 1);
properties.reverseLayout = a.getBoolean(R.styleable.RecyclerView_reverseLayout, false);

比如你在VM定义一个command，然后在view层使用了这个command,那么这个command的parameter就可以指向view层里的控件啊。控件作为parameter传进VM层的command里做逻辑处理。
