enter image description heream trying to get String and image url from database and display it on ListView using JDBC, the application every time show application force stop.
I tried to display the string on Toast and it's working 100%.
I am not sure where is the problem but i guess it's on View Holder, or on access the TextView and ImageView.
public class Viewholder{TextView textView; ImageView imageView; }
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View rowView=convertView;
Viewholder viewholder=null ;
if (rowView==null){
LayoutInflater inflater=getLayoutInflater(); rowView=inflater.inflate(R.layout.list_content,parent,false);
viewholder =new Viewholder();
viewholder.imageView =(ImageView)findViewById(R.id.imageView);
viewholder.textView =(TextView)findViewById(R.id.textview2);
rowView.setTag(viewholder);
name=parkinglist.get(position).getName();
Toast.makeText(context, name, Toast.LENGTH_SHORT).show();
}else {
viewholder =(Viewholder)convertView.getTag();
}
//i have error in next lines **************
viewholder.textView.setText(parkinglist.get(position).getName()+""); Picasso.with(context).load(parkinglist.get(position).getImg()).into(viewholder.imageView);
return rowView; }
