我有一个自定义ArrayAdapter来表示微调器控件上的对象,我可以加载我的项目列表并显示它以供选择,但是当实际选择发生时,微调器没有显示任何内容.

活动代码:

public MetroData metroData;
private Spinner spinner;

@Override
public void onCreate(Bundle savedInstanceState) {

StopArrayAdapter:

public class StopArrayAdapter extends ArrayAdapter<MetroStop> {

private List<MetroStop> items;
private Activity activity;

public StopArrayAdapter(Activity activity, List<MetroStop> items) {

    this.items = items;
    this.activity = activity;
}

@Override
public View getDropDownView(int position, View convertView, ViewGroup parent) {
    TextView v = (TextView) super.getView(position, convertView, parent);

    if (v …

这是我在清单文件中使用的代码.
