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

The RecyclerView has to use a GridLayoutManager.

This is a porting of the class SimpleSectionedListAdapter provided by Google

Centralize the support libraries dependencies in gradle

Working with multi-modules project, it is very useful to centralize the dependencies, especially the support libraries.

A very good way is to separate gradle build files, defining something like:

root
  --gradleScript
 ----dependencies.gradle

Centralize the firebase libraries dependencies in gradle

ext {
      firebaseVersion = '9.0.0';

      firebaseDependencies = [
              core :         "com.google.firebase:firebase-core:${firebaseVersion}",
              database :     "com.google.firebase:firebase-database:${firebaseVersion}",
              storage :      "com.google.firebase:firebase-storage:${firebaseVersion}",

The Material Components Library introduced with the 1.2.0-alpha03 the new ShapeableImageView.

In your layout you can use:

 <com.google.android.material.imageview.ShapeableImageView
      android:id="@+id/image_view"
      app:srcCompat="@drawable/..." />

Then in your code apply the ShapeAppearanceModel to define your custom corners:

	repositories {
	mavenCentral()
	//snapshot for rc1
	maven { url "https://oss.sonatype.org/content/repositories/snapshots/" }
	}


	dependencies {
	//Core card library
	compile 'com.github.gabrielemariotti.cards:cardslib-core:2.0.0-RC1-SNAPSHOT'

	ImageView imageView = (ImageView) findViewById(R.id.card_thumbnail_image);
	Bitmap mBitmap = BitmapFactory.decodeResource(getResources(), R.drawable.rose);

	if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP){
	//Default
	imageView.setBackgroundResource(R.drawable.rose);
	} else {
	//RoundCorners
	RoundCornersDrawable round = new RoundCornersDrawable(mBitmap,
	getResources().getDimension(R.dimen.cardview_default_radius), 0); //or your custom radius

	//Create a Card, set the title over the image and set the thumbnail
	CustomMaterialLargeImageCard card = (CustomMaterialLargeImageCard)
	CustomMaterialLargeImageCard.with(getActivity())
	.setTextOverImage("Italian Beaches "+i)
	.setTitle("This is my favorite local beach "+i)
	.setSubTitle("A wonderful place")
	.useDrawableId(R.drawable.sea)
	.setupSupplementalActions(R.layout.carddemo_native_material_supplemental_actions_large, actions)
	//It is important to use this build method
	.build(new CustomMaterialLargeImageCard(getActivity()));
