        Button button;
        ImageView image;
     
        @Override

            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
     
            button = (Button)findViewById(R.id.button);
            image = (ImageView)findViewById(R.id.image);
     
            //load image on button click
            button.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    Glide.with(MainActivity.this).load(IMAGE_URL).into(image);
                }
            });
        }
    }

5. Save and run the project.
