Android取消RecyclerView、ListView、ScrollView、HorizontalScrollView滑动到边缘闪现灰白色水波纹动画


标准的Android RecyclerView、ListView、ScrollView、HorizontalScrollView滑动到边缘,会闪现灰白色水波纹动画,以这样大的动画效果提示用户已经滑动到边缘,没法再滑动了。对于这种增强体验是一个很好的设计效果,但是有时候可能不需要这样的效果,取消的方法是在配置RecyclerView、ListView、ScrollView、HorizontalScrollView的xml布局里面,设置:
android:overScrollMode="never"
即可取消。

如果要在上层Java代码处理,也是可以,比如在Android官方的RecyclerView实现代码中:

   /**
     * Set the over-scroll mode for this view. Valid over-scroll modes are
     * {@link #OVER_SCROLL_ALWAYS} (default), {@link #OVER_SCROLL_IF_CONTENT_SCROLLS}
     * (allow over-scrolling only if the view content is larger than the container),
     * or {@link #OVER_SCROLL_NEVER}.
     *
     * Setting the over-scroll mode of a view will have an effect only if the
     * view is capable of scrolling.
     *
     * @param overScrollMode The new over-scroll mode for this view.
     */
    public void setOverScrollMode(int overScrollMode) {
        if (overScrollMode != OVER_SCROLL_ALWAYS &&
                overScrollMode != OVER_SCROLL_IF_CONTENT_SCROLLS &&
                overScrollMode != OVER_SCROLL_NEVER) {
            throw new IllegalArgumentException("Invalid overscroll mode " + overScrollMode);
        }
        mOverScrollMode = overScrollMode;
    }
在这里设置相应的mode一样可以。
