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"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;
}
