Android：AutoScrollViewPager放在PullToRefresh中，解決不能下拉刷新問題

AutoScrollViewPager：Android自動滾動，輪播循環的ViewPager。項目開源地址：https://github.com/Trinea/android-auto-scroll-view-pager

這個控件很方便的實現圖片banner的輪播，的確好用，但是我在項目中將AutoScrollViewPager放在下拉刷新ListView的頭部，當在AutoScrollViewPager控件上下拉的時候，不能實現下拉效果。這時就需要對mAutoScrollViewPager的onTouch事件進行重寫，核心代碼如下：

    private float mStartX;
    private float mStartY;
    private float mEndX;
    private float mEndY;

    mAutoScrollViewPager.setOnTouchListener(new OnTouchViewPagerListener());


    private class OnTouchViewPagerListener implements View.OnTouchListener {

        @Override
        public boolean onTouch(View v, MotionEvent event) {
            float minMove = 20;
            if (event.getAction() == MotionEvent.ACTION_DOWN) {
                mStartX = event.getX();
                mStartY = event.getY();
            }
            if (event.getAction() == MotionEvent.ACTION_MOVE) {
                mEndX = event.getX();
                mEndY = event.getY();
                float distanceX = mEndX - mStartX;
                float distanceY = mEndY - mStartY;
                if (Math.abs(distanceX) <= 15 && Math.abs(distanceY) >= minMove) {
                    v.getParent().requestDisallowInterceptTouchEvent(false);
                } else {
                    v.getParent().requestDisallowInterceptTouchEvent(true);
                }
            }
            return false;
        }
    }
