android - ViewGroup在dispatchDraw上导致StackOverflow

我有一个类重写viewgroup。下面是我对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());
}

不过，有时我会看到StackOverflower错误：

堆栈跟踪显示至少调用了4次com.ui.library.slidingmenu2.CustomViewAbove.dispatchDraw(CustomViewAbove.java:931)（即super.dispatchDraw(canvas)）。
只有当我返回到某个包含viewpager（其第一个片段包含gridview）的特定活动时，才会发生异常，而且只有一些时候。
（顺便问一下，什么是aBoringLayout）

最佳答案

必须有太多的层，尝试减少您的布局层。
