Refactored Report - New 'Class'

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

public class Report extends Base
{
    ListView listView;

    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_report);

        listView = (ListView) findViewById(R.id.reportList);
        DonationAdapter adapter = new DonationAdapter(this,  donations);
        listView.setAdapter(adapter);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_donate, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item)
    {
        switch (item.getItemId())
        {
            case R.id.menuDonate : startActivity (new Intent(this, Donate.class));
                break;
        }
        return super.onOptionsItemSelected(item);
    }
}

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

class DonationAdapter extends ArrayAdapter<Donation>
{
  private Context        context;
  public  List<Donation> donations;

  public DonationAdapter(Context context, List<Donation> donations)
  {
    super(context, R.layout.row_donate, donations);
    this.context   = context;
    this.donations = donations;
  }

  @Override
  public View getView(int position, View convertView, ViewGroup parent)
  {
    LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

    View     view       = inflater.inflate(R.layout.row_donate, parent, false);
    Donation donation   = donations.get(position);
    TextView amountView = (TextView) view.findViewById(R.id.row_amount);
    TextView methodView = (TextView) view.findViewById(R.id.row_method);

    amountView.setText("$" + donation.amount);
    methodView.setText(donation.method);

    return view;
  }

  @Override
  public int getCount()
  {
    return donations.size();
  }
}

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