    import android.view.ViewGroup;
    import android.widget.BaseAdapter;
    import android.widget.ImageView;
    import android.widget.TextView;
    
    import com.kannada.newspaper.india.R;
    import com.kannada.newspaper.india.models.Users;
    
    import java.util.ArrayList;
    
    public class GalleryAdapter extends BaseAdapter{
        private ArrayList<Users> users;
        private Context context;
    
        public GalleryAdapter(ArrayList<Users> users, Context context) {
            this.users = users;
            this.context = context;
        }
    
        @Override
        public int getCount() {
            return users.size();
        }
    
        @Override
        public Object getItem(int i) {
            return null;
        }
    
        @Override
        public long getItemId(int i) {
            return 0;
        }
    
        @Override
        public View getView(int i, View view, ViewGroup viewGroup) {
            LayoutInflater layoutInflater=(LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            view=layoutInflater.inflate(R.layout.custom_gallery_layout,null);
            ImageView photo,option;
            if(view==null){
                photo=new ImageView(context);
            }
            photo=(ImageView)view.findViewById(R.id.photo);
    
            TextView name=(TextView)view.findViewById(R.id.name);
    
            Users user=users.get(i);
            photo.setImageResource(user.getPhoto());
