实例如下：
public class CustomScrollView extends ScrollView {
private GestureDetector mGestureDetector;
View.OnTouchListener mGestureListener;
@SuppressWarnings("deprecation")
public CustomScrollView(Context context,AttributeSet attrs) {
super(context,attrs);
mGestureDetector= new GestureDetector(new YScrollDetector());
setFadingEdgeLength(0);
}
//通过手势判断，来判断是否拦截触摸事件。
@Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
return super.onInterceptTouchEvent(ev) && mGestureDetector.onTouchEvent(ev);
}
// Return false if we're scrolling in the x direction
class YScrollDetector extends SimpleOnGestureListener {
@Override
public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) {
if(Math.abs(distanceY) > Math.abs(distanceX)) {
return true;
}
return false;
}
}
}
