You can use this class to realize a simple sectioned RecyclerView.Adapter without changing your code.

The RecyclerView should use a LinearLayoutManager. You can use this code also with the TwoWayView with the ListLayoutManager (https://github.com/lucasr/twoway-view)

This is a porting of the class SimpleSectionedListAdapter provided by Google

Example:

JakeWharton

apply plugin: 'java'

sourceCompatibility = JavaVersion.VERSION_1_7
targetCompatibility = JavaVersion.VERSION_1_7

def logger = new com.android.build.gradle.internal.LoggerWrapper(project.logger)
def sdkHandler = new com.android.build.gradle.internal.SdkHandler(project, logger)
for (File file : sdkHandler.sdkLoader.repositories) {
  project.repositories.maven {
    url = file.toURI()
