Refactored Report - New ‘Class’

Finally, rework the Report class to remove the hard coded values - and use a different ‘adapter’

  1. public class Report extends Base {
  2.   private ListView listView;
  4.   @Override
  5.   public void onCreate(Bundle savedInstanceState) {
  6.     super.onCreate(savedInstanceState);
  7.     setContentView(R.layout.activity_report);
  9.     listView = (ListView) findViewById(R.id.reportList);
  10.     DonationAdapter adapter = new DonationAdapter(this, donations);
  11.     listView.setAdapter(adapter);
  12.   }
  13. }

This is the new adapter - DonationAdapter. You can place this at the end of the Report class (outside the closing brace) if you like:

  1. class DonationAdapter extends ArrayAdapter<Donation>
  2. {
  3.   private Context        context;
  4.   public  List<Donation> donations;
  6.   public DonationAdapter(Context context, List<Donation> donations)
  7.   {
  8.     super(context, R.layout.row_donate, donations);
  9.     this.context   = context;
  10.     this.donations = donations;
  11.   }
  13.   @Override
  14.   public View getView(int position, View convertView, ViewGroup parent)
  15.   {
  16.     LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
  18.     View     view       = inflater.inflate(R.layout.row_donate, parent, false);
  19.     Donation donation   = donations.get(position);
  20.     TextView amountView = (TextView) view.findViewById(R.id.row_amount);
  21.     TextView methodView = (TextView) view.findViewById(R.id.row_method);
  23.     amountView.setText("" + donation.amount);
  24.     methodView.setText(donation.method);
  26.     return view;
  27.   }
  29.   @Override
  30.   public int getCount()
  31.   {
  32.     return donations.size();
  33.   }
  34. }

If all goes well - then you should be able to make donations, and then see a list of them in the report activity.
