Android在ArrayAdapter<>里如何得到List<>的Items

时间:2021-10-19 20:20:06
public class ItemAdapter extends ArrayAdapter<DemoModel> {
private final List<DemoModel> items;
public AnswerItemAdapter(Context c, List<DemoModel> items) {
super(c, 0, items);
this.items = items;
} @Override
public View getView(int position, View convertView, ViewGroup parent) {
//Do something...
return convertView;
} public List<DemoModel> getItems() {
return items;
} }

当前,也可以使用list.clone()也克隆一份list。

然后在Activity里通过 adapter来获取items。

        List<ModeModel> items=ItemAdapter.getItems();
