Question

我使用适配器在列表中显示了10个不同的值。每个列表都有10个不同的值。如果我只有一个对象在列表中保存不同的值，那么我可以直接使用ArrayAdapter来过滤它。但就我而言，我正在使用不同的对象来显示值。现在我想根据单个值过滤列表。我怎样才能实现这种情况？

这是我的完整代码。

public class CustomEventAdapter extends BaseAdapter implements Filterable{
List<CalEvent> cont;
private CalEvent con;
private EventType event;
private EventStates states;
public static List<Meeting> mlist;
Context ctx;
TextView textView,textView2,textView3,textView4,textView5,textView6,textView7,actualend,meeting_place,meeting_person;
LayoutInflater inflater;
Context context;
public static Meeting meet;
static PendingIntent pendingIntent;
static AlarmManager alarmManager;
Button start_end_meet;
public CustomEventAdapter(Context ctx, List<CalEvent> cont) {
    this.ctx = ctx;
    this.cont = cont;
    inflater = (LayoutInflater) ctx
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}

@Override
public int getCount() {
    // TODO Auto-generated method stub
    return cont.size();
}

@Override
public CalEvent getItem(int position) {
    // TODO Auto-generated method stub
    return cont.get(position);
}

@Override
public long getItemId(int position) {
    // TODO Auto-generated method stub
    return cont.get(position).getId();
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    View rowView = convertView;
    if (convertView == null)
        rowView = inflater.inflate(R.layout.pd_eve_list_detail, parent,false);
    textView = (TextView) rowView.findViewById(R.id.start_Date);
    textView2 = (TextView) rowView.findViewById(R.id.actual_start);
    textView3 = (TextView) rowView.findViewById(R.id.requirement);
    textView4 = (TextView) rowView.findViewById(R.id.pd_event_type);
    textView5 = (TextView) rowView.findViewById(R.id.event_state);
    textView6 = (TextView) rowView.findViewById(R.id.current_stage);
    textView7 = (TextView) rowView.findViewById(R.id.notes);
    meeting_place = (TextView) rowView.findViewById(R.id.meeting_place);
    meeting_person = (TextView) rowView.findViewById(R.id.meet_person);
    con = getItem(position);
    event = EventType.getEventType(con.event_type);
    states = EventStates.getEventStates(con.event_state);
    try {
        textView5.setText(states.name);
        textView.setText(con.event_start);
        textView2.setText(con.actual_start);
        textView4.setText(event.name);
        textView7.setText(con.notes);
        meeting_place.setText(con.followup_location);
        meeting_person.setText(con.person_met);
        System.out.println(event.name+states.name+con.followup_location);
    }catch (Exception e) {
    }
    return rowView;
}

请帮帮我。提前谢谢。

我建议你使用这个组件：

https://github.com/matessoftwaresolutions/AndroidFilterableList

此组件允许您以dinamically方式过滤，按对象的属性进行过滤等。

您只需要使用其方法实现两个接口......不再需要。请参阅相关说明。

您还可以找到一个样本，这将使您的实施更加轻松。

给它一个机会!!我希望这会对你有所帮助;）
