我也遇到了这个问题，设置marginBottom有时候会变成marginTop,而且大小也不对，有时候margin又消失没有了
我是使用了一个adapter作为divider，去设置背景、高度，在divider的adapter内部设置view的layoutparam 从而设置 margin、padding
更新下我遇到的问题，之前有遇到过这样的异常 ``` Inlined method resolution crossed dex file boundary: from androidx.lifecycle.LifecycleCoroutineScope androidx.lifecycle.LifecycleKt.getCoroutineScope(androidx.lifecycle.Lifecycle) in /data/app/~~0d517gkZ5K6RSn2_ejprRg==/com.xiaolachuxing.driver- r5nbB3wUsZHUlm0t2mRWhw==/base.apk/0x7f009c1380 to void androidx.lifecycle.LifecycleCoroutineScopeImpl.register() in /data/user/0/com.xiaolachuxing.driver/tinker/patch-a414dddb/dex/tinker_classN.apk/0x7f13495b40. This must be due to duplicate classes or playing wrongly...
把tinker的加固打开试试 ``` tinkerPatch { buildConfig { isProtectedApp = true .... ```
