如何监听下拉滚动的y值

[xxchenqi]

你好:
此方法不是实时监听的，手放掉的时候就监听不到了,如何修改做到实时监听
mRefreshLayout.setRefreshScaleDelegate(new BGARefreshLayout.BGARefreshScaleDelegate() {
@OverRide
public void onRefreshScaleChanged(float scale, int moveYDistance) {
Log.i(TAG, "scale:" + scale + " moveYDistance:" + moveYDistance);
}
});
