How to open an Image in new activity when clicked in viewpager?

Question

I'm using viewpager to display the slideshow of the images but when I'm clicked on any one of the image it need to opened in new activity. Can anyone help me?

I'm displaying toast message when clicked on image but my actually requirement is to open the image in new activity.

The code is below:

class MyCustomPagerAdapter extends PagerAdapter{
private Context context;
private int images[];
private LayoutInflater layoutInflater;
public int i;

MyCustomPagerAdapter(Context context, int images[]) {
    this.context = context;
    this.images = images;
    layoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}

@Override
public int getCount() {
    return images.length;
}

@Override
public boolean isViewFromObject(View view, Object object) {
    return view == object;
}

@Override
public Object instantiateItem(final ViewGroup container, final int position) {
    View itemView = layoutInflater.inflate(R.layout.full_profile, container, false);

    ImageView imageView = (ImageView) itemView.findViewById(R.id.expandedImage);
    imageView.setImageResource(images[position]);

    container.addView(itemView);

    //listening to image click
    imageView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            //Toast.makeText(context, "you clicked image " + (position + 1), Toast.LENGTH_SHORT).show();
            Intent intent = new Intent(context, ImageOpeningActivity.class);
            intent.putExtra("MY_IMAGE", images[position]);
            context.startActivity(intent);

        }
    });

    return itemView;
}

@Override
public void destroyItem(ViewGroup container, int position, Object object) {
    container.removeView((View) object);
}

}

ImageOpeningActivity.class

class ImageOpeningActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.imageopening);



    ImageView imageView = (ImageView) findViewById(R.id.myImageView);

    if(getIntent()!=null){
        int image  = getIntent().getExtras().getInt("MY_IMAGE");
        imageView.setImageResource(image);
    }
}

}

although i changed my code i getting an error, the error is below.

 java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{com.vmax.kalyanam/com.vmax.kalyanam.ImageOpeningActivity}: java.lang.IllegalAccessException: java.lang.Class<com.vmax.kalyanam.ImageOpeningActivity> is not accessible from java.lang.Class<android.app.Instrumentation>

public class Full_profile extends Activity {
Toolbar toolbar;
CollapsingToolbarLayout collapsingToolbarLayout;
//public String title = "KANDIBANDA ROJA";


protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.full_profile);


    ViewPager viewPager;
    int images[] = {
            R.drawable.one,
            R.drawable.two,
            R.drawable.three,
            R.drawable.one
    };

    MyCustomPagerAdapter myCustomPagerAdapter;
    viewPager = (ViewPager)findViewById(R.id.viewPager);
    myCustomPagerAdapter = new MyCustomPagerAdapter(Full_profile.this, images);
    viewPager.setAdapter(myCustomPagerAdapter);

put intent here in "listening to image click"

      imageView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
               Intent intent = new Intent(this,PhotoViewerActivity.class);
intent.putExtra("image", imageurl);
    startActivity(intent);
            }
        });



public class PhotoViewerActivity extends Activity {

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState); 


        String url = getIntent().getStringExtra("image");
     // you can show image from url using library like glide or picasso
    }

    @Override
    protected int getLayoutResourceId() {
        return R.layout.activity_photo_viewer;
    }

    @Override
    public void onBackPressed() {
        PhotoViewerActivity.this.finish();
    }
}
