#RecyclerView-in-Kotlin

#Creating a new Android Project with Kotlin in Android Studio.

#Add Dependencies in build.gradle file

//picasso is an image loading/processing library implementation 'com.squareup.picasso:picasso:2.71828'

//Retrofit Networking library implementation "com.squareup.retrofit2:retrofit:2.3.0"

//Gson is a library that can be used to convert Java Objects into their JSON representation implementation "com.squareup.retrofit2:converter-gson:2.3.0"

//RecyclerView implementation 'com.android.support:recyclerview-v7:27.1.1'

#Adding User Interface in your main Layout file

<android.support.v7.widget.RecyclerView android:id="@+id/recyclerView" android:layout_width="match_parent" android:layout_height="match_parent" android:scrollbars="vertical"/>

#Create a single row item for your RecyclerView.

#Create a Model Class

data class MovieModel( @SerializedName("title") @Expose var title: String? = null, @SerializedName("image") @Expose var image: String? = null, @SerializedName("rating") @Expose var rating: Double? = null, @SerializedName("releaseYear") @Expose var releaseYear: Int? = null, @SerializedName("genre") @Expose var genre: List? = null)

#Create a Adapter class

Here, I created a custom adapter name MovieAdapter with ViewHolder.

The Holder contains the members of the layout to bind viewItems.

Hear I used Picasso library for image loading. Picasso.get().load(movieModel.image).into(itemView.imageView_movie)

#Creating RecyclerView And Set Data To Adapter Class

    var linearLayoutManager = LinearLayoutManager(this)
    var adapter = MovieAdapter(arrList)
    recyclerView.layoutManager = linearLayoutManager
    recyclerView.adapter = adapter
