You can find the source code here,git,it's not my repo.

I want to open a new activity when a specific book or item is clicked.

I use Recyclerview to display the books in grid.

How handle on clicks, where and how to implement them,thanks in advance.

book.java

public class Book {



private String Title;

private String Category ;

private String Description ;

private int Thumbnail ;



public Book() {

}



public Book(String title, String category, String description, int 

thumbnail) {

    Title = title;

    Category = category;

    Description = description;

    Thumbnail = thumbnail;

}





public String getTitle() {

    return Title;

}



public String getCategory() {

    return Category;

}



public String getDescription() {

    return Description;

}



public int getThumbnail() {

    return Thumbnail;

}





public void setTitle(String title) {

    Title = title;

}



public void setCategory(String category) {

    Category = category;

}



public void setDescription(String description) {

    Description = description;

}



public void setThumbnail(int thumbnail) {

    Thumbnail = thumbnail;

}

}

book activity.java

    import android.content.Intent;

import android.support.v7.app.AppCompatActivity;

import android.os.Bundle;

import android.widget.ImageView;

import android.widget.TextView;



public class Book_Activity extends AppCompatActivity {



private TextView tvtitle,tvdescription,tvcategory;

private ImageView img;



@Override

protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_book_);



    tvtitle = (TextView) findViewById(R.id.txttitle);

    tvdescription = (TextView) findViewById(R.id.txtDesc);

    tvcategory = (TextView) findViewById(R.id.txtCat);

    img = (ImageView) findViewById(R.id.bookthumbnail);



    // Recieve data

    Intent intent = getIntent();

    String Title = intent.getExtras().getString("Title");

    String Description = intent.getExtras().getString("Description");

    int image = intent.getExtras().getInt("Thumbnail") ;



    // Setting values



    tvtitle.setText(Title);

    tvdescription.setText(Description);

    img.setImageResource(image);





}
