ViewGroup在dispatchDraw中导致StackOverflow

我有一个重写ViewGroup的类。这是我对dispatchDraw的实现：

@Override
protected void dispatchDraw(final Canvas canvas) {
    super.dispatchDraw(canvas);

    mViewBehind.drawShadow(mContent, canvas);
    mViewBehind.drawFade(mContent, canvas, getPercentOpen());
    mViewBehind.drawSelector(mContent, canvas, getPercentOpen());
}

但是，有时我得到这个StackOverflowError：

堆栈跟踪显示com.ui.library.slidingmenu2.CustomViewAbove.dispatchDraw(CustomViewAbove.java:931)（super.dispatchDraw(canvas)）被调用至少4次。

只有在我返回某个包含ViewPager的活动时才会发生异常，该活动的第一个片段包含一个GridView，并且只有一些时间。

（顺便说一句，反正什么是BoringLayout？）
