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:

ZkHaider

public static class ExampleViewHolder extends RecyclerView.ViewHolder 
    implements View.OnClickListener {

    private int originalHeight = 0;
    private boolean isViewExpanded = false;
    private YourCustomView yourCustomView
    
    public ExampleViewHolder(View v) {
     super(v);
     v.setOnClickListener(this);

        cameraFileName = Constants.DOWNLOAD_IMAGE_PATH + System.currentTimeMillis();
        File file = new File(Constants.DOWNLOAD_IMAGE_PATH);
        if(!file.exists()){
            file.mkdirs();
        }
        intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File(cameraFileName)));

Unless specified otherwise, all of the below tinting applies to both Lollipop and pre-Lollipop using AppCompat v21. 
To use the support version of these attributes, remove the android namespace.  

For instance, "android:colorControlNormal" becomes "colorControlNormal".  

These attributes will be propagated to their corresponding attributes within the android namespace 
for devices running Lollipop.  Any exceptions to this will be noted by including the "android:" prefix.
