int defStyleRes) {
Properties properties = getProperties(context, attrs, defStyleAttr, defStyleRes);
setOrientation(properties.orientation);

public static Properties getProperties(Context context, AttributeSet attrs,
int defStyleAttr, int defStyleRes) {
Properties properties = new Properties();
TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.RecyclerView,
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);
properties.stackFromEnd = a.getBoolean(R.styleable.RecyclerView_stackFromEnd, false);
a.recycle();
return properties;
