verticalviewpager's Issues

实现的方式很巧妙，想到一个点上去了，但还需要解决一些滑动冲突

The Sample is working

I have downloading the source code and extracted the sample project as a new project but it's not working

Add ListView item in fragment

Great example thanks for that.
Can we add List item to each fragment in a bundle?
one item from list for each fragment.

有一个小的问题，当在Fragment添加SurfaceView的时候，出现的

我遇到的问题是，Fragment添加SurfaceView，触摸屏幕的时候，会造成一个问题 SurfaceView 会被隐藏，显示出底部背景，从而造成闪现背景，最后我发现其实子页并非在最上面，所以触摸事件被隐藏在其上面的View给消费了，我的解决方案是在VerticalViewPager中重写onPageScrolled和setPageTransformer，下面是我的解决方案的源码
`
@OverRide
protected void onPageScrolled(int position, float offset, int offsetPixels) {
super.onPageScrolled(position, offset, offsetPixels);
// 下面的源码来自super.onPageScrolled()
int scrollX;
int childCount;
int i;
if (this.mPageTransformer != null) {
scrollX = this.getScrollX();
childCount = this.getChildCount();

        for (i = 0; i < childCount; ++i) {
            View var15 = this.getChildAt(i);
            ViewPager.LayoutParams var16 = (ViewPager.LayoutParams) var15.getLayoutParams();
            if (!var16.isDecor) {
                float var17 = (float) (var15.getLeft() - scrollX) / (float) this.getClientWidth();
                this.mPageTransformer.transformPage(var15, var17);
            }
        }
    }
}

private int getClientWidth() {
    return this.getMeasuredWidth() - this.getPaddingLeft() - this.getPaddingRight();
}

@Override
public void setPageTransformer(boolean reverseDrawingOrder, ViewPager.PageTransformer transformer) {
    super.setPageTransformer(reverseDrawingOrder, null);
    mPageTransformer = transformer;
}`

 java.lang.IllegalArgumentException: pointerIndex out of range
   at android.view.MotionEvent.nativeGetAxisValue(Native Method)
   at android.view.MotionEvent.getX(MotionEvent.java:2139)
   at android.support.v4.view.ViewPager.onInterceptTouchEvent(ViewPager.java:2064)

my answer:

 @Override
    public boolean onInterceptTouchEvent(MotionEvent event) {
        try {
            boolean intercept = super.onInterceptTouchEvent(swapTouchEvent(event));
            //If not intercept, touch event should not be swapped.
            swapTouchEvent(event);
            return intercept;
        } catch (IllegalArgumentException e) {
            e.printStackTrace();
        }
        return false;
    }

    @Override
    public boolean onTouchEvent(MotionEvent ev) {
        try {
            return super.onTouchEvent(swapTouchEvent(ev));
        } catch (IllegalArgumentException e) {
            e.printStackTrace();
        }
        return false;
    }

Vertical Swipe

I still have to swipe horizontally in order for it to scroll. Anyway to switch that to swipe vertically instead? Everything else works perfect, thank you :)
