    @vone 应该不是,切换完其他 app 这个悬浮窗应该会消失。而且没有给 SYSTEM_ALERT_WINDOW 权限

    看了半天 swift,自己人肉转了一个。用的不对的地方,还请各位指正

    @DeweyReed 今天试了一下 paging + room,通过 onZeroItemsLoaded 初始化数据,onItemAtEndLoaded 拉取后面的数据,测试基本功能可用,但是 onItemAtFrontLoaded 数据会有问题,onItemAtFrontLoaded 开始就会执行,而且 RecyclerView 定位到 onItemAtFrontLoaded 的第一条数据,而不是 onZeroItemsLoaded 的第一条数据。不知道是不是我对 PagedList.BoundaryCallback 理解不对,还是有别的方法?
    @DeweyReed 用 paging 刷新时也会卡一下的,感觉是靠 SCROLL_STATE_IDLE 触发的加载数据,没有 onScrolled 里做的加载顺滑
    在 AppTheme 里加了个配置 <item name="android:fontFamily">miui</item> 在小米手机上实现了跟微信一样的效果
    但是在华为手机上会崩溃。xml 文件里似乎是不能判断机型,全局字体有没有办法可以通过代码配置?
