項(xiàng)目的gradle

project的build.gradle:

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

module的build.gradle

compile 'com.github.githubwing:ByeBurger:1.2.3'

//Demo中用到了RecyclerView 和Design中的ui
compile 'com.android.support:recyclerview-v7:29.0.1'
compile 'com.android.support:design:29.0.1'
