Android DataBinding 采坑记录

NoClassDefFoundError: Failed resolution of: Landroidx/databinding/DataBinderMapperImpl

app module 和 相关的 子 module 均需配置

android {

    dataBinding {
        enabled = true
    }
}

Cause: couldn't make a guess for xxx

Cause: couldn't make a guess for cc.androidx.app_widget.adapter.BaseRecyclerViewAdapter.entity.Person

错误分析: 问题出在type引用对象的包名包含了大写
解决方法: 包路径都为小写

<data>
    <variable
        name="person"
        type="cc.androidx.app_widget.adapter.brva.entity.Person"/>

    <variable
        name="presenter"
        type="cc.androidx.app_widget.adapter.brva.entity.PersonPresenter"/>
</data>
