我被这崩溃弄烦死了，我让一个懂代码的用户帮忙调试了，发现问题很奇怪，我这边没设备可以重现 那个用户是因为切换主题才崩溃，崩溃的地方也是这里 原因是 AbstractAppListAdapter ListView 有3种类型的 item 视图：【小图】，【大图】和【载入中间】 getView 的时候，switch 语句生成View，原本应该是【小图】或【大图】，结果却生成了【载入中间】视图，接着就是找不到对应的控件，空指针了 之所以难办在于，如果是逻辑错误，那么我这边肯定能重现，但是根据用户帮忙调试来看，去读取的 xml 是正确的，但是出来的 View 却是错的 你要是能帮忙那是最好了 |
|
后台记录的因为这个问题引起的崩溃都快破800了 T.T |
|
唔，略懂一点安卓，我尝试着帮忙看看。 而且，刚刚很奇怪的是，用Wi-Fi环境没有FC就直接进去了… 囧rz |
|
不知道是不是由于这个帖子里面提到的原因，一个 == null 的判断 https://groups.google.com/forum/#!topic/android-developers/9rwYvsfG_fg |
|
不一样啊，我这边是读取了R.layout.timeline_listview_item_layout，生成了R.layout.timeline_listview_item_middle_layout |
|
你会发现，进了294行，生成的应该是个RelativeLayout，结果出来的是FrameLayout |
|
我在使用FrameLayout布局时出现过这样的问题：调用findViewbyId得不到该id的控件，得到的是FrameLayout的第一个子控件，然后就报classCastExeception 你会发现，进了294行，生成的应该是个RelativeLayout，结果出来的是FrameLayout — |
|
@izzyleung 你说的是对的 我优化来优化去，结果出了逻辑漏洞 |
|
已经修正 这bug隐藏太深，我一年都没发现，我这边从没因为这个崩溃过 |

@qii Great! 唔，对了，新版更新之后，org.qii.weiciyuan.support.utils.GlobalContext 里面增加了 Crashlytics 的内容，最好在 README 里面更新一下，告诉大家把他们注释掉吧~ ;-D |
四次元基于最新版本 Gradle 构建。在从 3G 环境转换至家中的 Wi-Fi 环境后，打开四次元永远 FC。但是切换至 3G 环境，软件可以正常打开。
机型：Meizu MX II（Genymotion 不支持 3G 模拟，所以无法用它重现问题，很抱歉）
StackTrace 如下：
