我是打算把demo中的图片位置换成viewview播放视频 然后出现这个问题了

@smarthityou 按理只是替换控件，不会有问题，自己分析下，看还改了哪里

在SwipeFlingAdapterView中的makeAndAddView中FrameLayout.LayoutParams lp = (FrameLayout.LayoutParams) child.getLayoutParams();下面各个获取lp.topMargin + lp.bottomMargin会报空指针

@smarthityou 你不是用inflater.inflate(layoutId, parent, false)方法实例化view的吧，导致LayoutParams为空

我是在适配器里面用的，但也不至于这样吧。然后我在child.getLayoutParams();下面各个获取lp.topMargin + lp.bottomMargin用了try语句 如果出错就不获取lp.topMargin + lp.bottomMargin然后就不会有问题了 。 还有个问题就是 如果加上videoView的话锯齿就更严重了。
