CustomAdapter.Java

public class SearchJobsCustomList extends BaseAdapter implements View.OnClickListener {
    Context c;
    ArrayList<HashMap<String, String>> data;

    HashMap<String, String> resultp = new HashMap<String, String> ();


    public SearchJobsCustomList(Context c, ArrayList<HashMap<String, String>> data) {
        super ();
        this.c = c;
        this.data = data;


    }
