几个比较常用的jar包

 implementation 'com.android.support:recyclerview-v7:26+'
implementation 'org.greenrobot:eventbus:3.1.1'
compile 'jp.wasabeef:glide-transformations:3.0.1'
implementation 'com.squareup.retrofit2:converter-gson:2.3.0'
implementation 'com.squareup.retrofit2:retrofit:2.3.0'
implementation 'com.squareup.okhttp3:okhttp:3.9.0'


implementation 'com.android.support:design:26.1.0'



implementation 'com.jakewharton:butterknife:8.8.1'
annotationProcessor 'com.jakewharton:butterknife-compiler:8.8.1'

implementation 'org.greenrobot:eventbus:3.1.1'
implementation 'com.ashokvarma.android:bottom-navigation-bar:1.3.0'
implementation 'com.android.support:cardview-v7:26.1.0'

implementation 'com.android.support:design:26.1.0'

如果在android studio 搜不出来的话可以把他们直接添加到build里面

compile 'com.squareup.retrofit2:converter-gson:2.3.0'

compile 'com.squareup.okhttp3:okhttp:3.9.0'

compile 'com.mcxiaoke.next:recycler:1.5.0'   

compile 'com.github.bumptech.glide:glide:3.7.0' 

compile 'eu.the4thfloor.volley:com.android.volley:2015.05.28' 

compile 'com.google.code.gson:gson:2.8.2'
