触摸EditText / Button时，ViewPager不可滚动

Question

我正在使用VerticalViewPager滚动浏览两个片段，但是当我触摸EditText / Buttons时，滚动功能无效... 仅限观点...

public class VerticalViewPager extends ViewPager {

    public VerticalViewPager(Context context) {
        this(context, null);
    }

    public VerticalViewPager(Context context, AttributeSet attrs) {
        super(context, attrs);
        setPageTransformer(true, new DefaultTransformer());
    }

    private MotionEvent swapTouchEvent(MotionEvent event) {
        float width = getWidth();
        float height = getHeight();

        float swappedX = (event.getY() / height) * width;
        float swappedY = (event.getX() / width) * height;

        event.setLocation(swappedX, swappedY);

        return event;
    }

    public boolean onInterceptTouchEvent(MotionEvent event) {
        swapTouchEvent(event);
        return super.onInterceptTouchEvent(swapTouchEvent(event));
    }

    public boolean onTouchEvent(MotionEvent ev) {
        return super.onTouchEvent(swapTouchEvent(ev));
    }

}

我该怎么办？ 感谢
