框架引入

先在 build.gradle(Project:XXXX) 的 repositories 添加:

    allprojects {        repositories {            ...            maven { url "https://jitpack.io" }        }    }

然后在 build.gradle(Module:app) 的 dependencies 添加:

    dependencies {            compile 'com.github.CymChad:BaseRecyclerViewAdapterHelper:2.9.22'    }

在此感谢， BRVAH是一个强大的RecyclerAdapter框架。
