android - DispatchDraw で StackOverflow を引き起こす ViewGroup

Question

ViewGroup をオーバーライドするクラスがあります。これがdispatchDrawの私の実装です：

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

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

ただし、次の StackOverflowError が発生することがあります。

スタックトレースは、com.ui.library.slidingmenu2.CustomViewAbove.dispatchDraw(CustomViewAbove.java:931)(これはsuper.dispatchDraw(canvas)) が少なくとも 4 回呼び出されていることを示しています。

例外は、最初の Fragment に GridView が含まれている ViewPager を含む特定のアクティビティに戻ったときにのみ発生します。

（ところで、BoringLayoutとにかく何ですか？）

レイヤーが多すぎる必要があります。レイアウトレイヤーを減らしてみてください。

BoringLayout は、1 行に収まるすべて左から右の文字で構成されるテキストの非常に単純な Layout 実装です。
