// app compact
implementation "androidx.appcompat:appcompat:1.1.0-alpha04"

// constraint layout
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'

// recycle view
implementation 'androidx.recyclerview:recyclerview:1.1.0-alpha04'


// glide

implementation 'com.github.bumptech.glide:glide:4.9.0'
annotationProcessor 'com.github.bumptech.glide:compiler:4.9.0'

**3. Use androidxRecycleview in view layout activity_main.xml **

` <androidx.recyclerview.widget.RecyclerView

    android:id="@+id/recycle_view_book"
    
    android:layout_width="match_parent"
    
    android:layout_height="match_parent"
    
    android:clipToPadding="false"
    
    android:layout_marginTop="?android:attr/actionBarSize"
    
    app:layout_constraintTop_toBottomOf="@+id/appbar"
    
    app:layout_constraintBottom_toBottomOf="parent"
    
    app:layout_constraintTop_toTopOf="@+id/appbar"
    
    app:layoutManager="androidx.recyclerview.widget.LinearLayoutManager" />

**4. Set Adapter in MainActivity.class **

    private fun setRecycleViewList() {

    val recyclerView = findViewById<RecyclerView>(R.id.recycle_view_book)
    
    val mAdapter = BooksAdapter(this@MainActivity, bookList)
    
    val mLayoutManager = LinearLayoutManager(applicationContext)
    
    recyclerView.layoutManager = mLayoutManager
    
    recyclerView.itemAnimator = DefaultItemAnimator()
    
    recyclerView.adapter = mAdapter
    
}


val bookList: List<Book>
    get() {

        val bookList = ArrayList<Book>()
        book = Book()
        book.bookTitle = "My Story"
        book.authorName = "John Deo"
        book.bookImage = "https://0.s3.envato.com/files/183895378/preview%20image_590x300.jpg"
        book.publishedYear = 1997
        bookList.add(book)

        book = Book()
        book.bookTitle = "White Dragon"
        book.authorName = "unknown"
        book.bookImage = "https://arthive.com/res/media/img/oy800/work/e58/183471.jpg"
        book.publishedYear = 2005
        bookList.add(book)


        book = Book()
        book.bookTitle = "XuGkeTK"
        book.authorName = "unknown"
        book.bookImage = "http://i.imgur.com/XuGkeTK.jpg"
        book.publishedYear = 2009
        bookList.add(book)
