通过代码给CoordinatorLayout中的子view设置Behavior

example.java

...
@ViewInject(R.id.page_two)
private NestedScrollView pageTwo;
...

...
CoordinatorLayout.LayoutParams layoutParams = (CoordinatorLayout.LayoutParams) pageTwo.getLayoutParams();
layoutParams.setBehavior(new PageBehavior(mAct, new PageBehavior.OnSwitchListener() {
    @Override
    public void onSwitch(int page) {
        Log.d("kaka", "onSwitch: "+page);
    }
}));
