经调查，发现这是 Android 的 ViewPager 的一个 bug，偶尔会在用户执行多点触控操作时发生。直到至少 Android 4.4，该问题依然存在。

解决方案也很简单，覆写 ViewPager 的 onTouchEvent 与 onInterceptTouchEvent 方法，catch 该异常即可，如下所示：

@Override    public boolean onTouchEvent(MotionEvent me) {        try {            return super.onTouchEvent(me);        } catch (IllegalArgumentException ex) {            ex.printStackTrace();        }        return false;    }
