错误: 无法将类 BindingRecyclerViewAdapters中的方法 setAdapter应用到给定类型; 需要: RecyclerView,ItemBinding<? super T>,List<T>,BindingRecyclerViewAdapter<T>,ItemIds<? super T>,ViewHolderFactory,AsyncDifferConfig<T> 找到: RecyclerView,ItemBinding<ContactItemViewModel>,ObservableList<ContactItemViewModel>,ContactAdapter,ItemIds,ViewHolderFactory,AsyncDifferConfig 原因: 推论变量 T 具有不兼容的限制范围 等式约束条件: CompanyInfo,ContactItemViewModel 上限: ContactItemViewModel,Object 其中, T是类型变量: T扩展已在方法 <T>setAdapter(RecyclerView,ItemBinding<? super T>,List<T>,BindingRecyclerViewAdapter<T>,ItemIds<? super T>,ViewHolderFactory,AsyncDifferConfig<T>)中声明的Object

android.build.gradle version 3.5.3 and setAdapter in Activity/Fragment（not in ViewModel）, This is different from the sample code

If I define the adapter in the ViewModel like the simple code, there is no problem, But I don't know if this code will cause a memory leak?

1. build.gradle Modify upgrade in file： classpath 'com.android.tools.build:gradle:3.6.3'

2. gradle-wrapper.properties Modify upgrade in file： distributionUrl=https://services.gradle.org/distributions/gradle-5.6.4-all.zip

在xml导入的类名后面加入 <Object>试试.

<variable
            name="ViewModel"
            type="xxx.xxx.DataListViewModel&lt;Object>" />
