PullToRefreshScrollView实现y轴滑动监听

用法:

@ViewInject(R.id.sv)
PullToRefreshScrollView sv;

//y轴滑动监听
sv.setScrollViewListener(new ObservableScrollView.ScrollViewListener() {
    @Override
    public void onScrollChanged(ObservableScrollView scrollView, int x, int y, int oldX, int oldY) {
        Log.i("====","y"+y);
    }
});
//上拉下拉的y轴监听
ObservableScrollView refreshableView = sv.getRefreshableView();
refreshableView.setPullScrollViewListener(new PullToRefreshScrollView.PullScrollViewListener() {
    @Override
    public void onScrollChanged(PullToRefreshScrollView pullToRefreshScrollView, int x, int y, int oldX, int oldY) {
        Log.i("====","y"+y);
    }
});

源码稍作修改:
