List<Integer> image;
Activity context;
public CustomView( Activity context, List<Integer> image,List<String> date, List<String> description) {
super(context, R.layout.urlop,date);
this.context=context;
this.image=image;
this.date=date;
this.description=description;
}
@NonNull
@Override
public View getView(int position, @Nullable View convertView, @NonNull ViewGroup parent) {
ViewHolder vv=null;
if(convertView==null)
{
LayoutInflater layoutInflater=context.getLayoutInflater();
convertView=layoutInflater.inflate(R.layout.urlop,null,true);
vv=new ViewHolder(convertView);
convertView.setTag(vv);
}else {
vv= (ViewHolder) convertView.getTag();
}
vv.img.setImageResource(image.get(position));
vv.dd.setText(date.get(position));
vv.desc.setText(description.get(position));
return convertView;
}
class ViewHolder{
TextView dd;
TextView desc;
ImageView img;
ViewHolder(View v){
dd=(TextView) v.findViewById(R.id.data);
desc=(TextView) v.findViewById(R.id.description);
img=(ImageView) v.findViewById(R.id.imageView);
