Question

我有一个ExpandableListView列表工作得很好但我想当我点击Childs一个时钟图标改变颜色并做一些事情并保存但当我点击孩子时第一个时钟第一个孩子做了工作，但当我向下滚动一个随机的孩子或者其中2 3 3也会改变颜色，如果我关闭应用程序这个os我的适配器代码将保存

public class exTourListAdapter extends BaseExpandableListAdapter {

private Context context;
private ArrayList<GroupTour> groups;
private int count;
SharedPreferences preferences;
AppCompatTextView timeTour ,tvPrize ,tvGameMode,tvBuyIn,tvLateReg
,tvReBuy,tvDays;
RelativeLayout childToursLayout;


Clock clock ;
public exTourListAdapter(Context context , ArrayList<GroupTour> groups,int count) {
    this.context = context;
    this.groups = groups;
    this.count = count;
}

@Override
public ChildTour getChild(int groupPosition, int childPosition) {
    GroupTour group = groups.get(groupPosition);
    exChild exchild = group.getChildren().get(groupPosition);
    ChildTour child = exchild.getChildTours().get(childPosition);
    return child;
}

@Override
public long getChildId(int groupPosition, int childPosition) {
    ChildTour childTour= getChild(groupPosition,childPosition);
    int id= childTour.getTourId();
    return id;
}

    if (convertView == null) {

    tvDays.setTag(child.getTourId());
    clock.setHours(child.getHour());
    clock.setMinutes(child.getMin());

    tvLateReg.setText("Late Register: "+child.getLateReg()+" min");
    int id = (int) getChildId(groupPosition,childPosition);

    }
    if (child.getReBuy().equals("")){
        tvReBuy.setText("Rebuy: ?");
    }else {
        tvReBuy.setText("Rebuy: "+child.getReBuy());
    }
    tvDays.setText(child.getDay());

    return convertView;

}

@Override

   int number = groups.get(groupPosition).getChildren().get(groupPosition).getChildNumbers();

    return number;
}

这是我的片段代码，Clock类是Clock Icon

public class ListToursexFragment extends Fragment {
SwipeRefreshLayout refresh;
ExpandableListView listView;
SharedPreferences.Editor editor;
SharedPreferences pref;
@Nullable
@Override
public View onCreateView(LayoutInflater inflater,
                         @Nullable ViewGroup container,
                         @Nullable Bundle savedInstanceState) {
    View view= inflater.inflate(R.layout.activity_tours,container,false);
    pref= getActivity().getSharedPreferences("timeonoff", Context.MODE_PRIVATE);
    editor =pref.edit();
    refresh = (SwipeRefreshLayout) view.findViewById(R.id.refresh_tours);
    listView = (ExpandableListView) view.findViewById(R.id.list_tours);
    refresh.setColorSchemeColors(
            R.color.material_green_200,
            R.color.material_green_400,
            R.color.material_green_600,
            R.color.material_green_800
    );
    refresh.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
        @Override
        public void onRefresh() {
            prepareData(url,listView);
        }
    });
    prepareData(url,listView);
    return view;
}

    JsonObjectRequest request = new JsonObjectRequest(Request.Method.GET, url, null, new Response.Listener<JSONObject>() {
        @Override

            try {

                JSONArray array = response.getJSONArray("sites");
                int count = response.getInt("sitescount");
                exTourParser parser = new exTourParser();
                final ArrayList<GroupTour> items = parser.Parse(array);

                exTourListAdapter adapter = new exTourListAdapter(getContext(), items,count);
                listView.setAdapter(adapter);

                        Clock clock = (Clock) view.findViewById(R.id.clock_layour);
                        boolean b= pref.getBoolean("time"+id,false);
                        if (b ==true){
                            editor.putBoolean("time"+id,false);
                            editor.commit();
                            clock.setClockColor(R.color.material_brown_700);
                        }else if (b == false){
                            editor.putBoolean("time"+id,true);
                            editor.commit();
                            clock.setClockColor(R.color.material_green_700);
                        }
                        return false;

                    }
                });
            } catch (JSONException e) {
                e.printStackTrace();
            }
        }
    }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            Toast.makeText(getContext(), "ridiok", Toast.LENGTH_SHORT).show();
        }
    });
    RequestQueue quew = Volley.newRequestQueue(getActivity().getApplicationContext());
    quew.add(request);
}

此屏幕截图 first second仅点击第一个孩子然后滚动几次然后发生黑色是默认颜色

Answer 1

当您在适配器的getView方法内部工作时，您在其中使用IF条件，然后尝试使用“else”。在你的情况下，我可以看到'if'和'else if'，而

否则

缺失。

 if (b)
    {
                 editor.putBoolean("time"+id,false);
                 editor.commit();
                 clock.setClockColor(R.color.material_brown_700);
    }
    else 
    {
              editor.putBoolean("time"+id,true);
              editor.commit();
              clock.setClockColor(R.color.material_green_700);
    }

可以转换为

$spilt=explode(',',$newstyle);
          foreach ($spilt as $splitkey => $splitvalue) {
            if ($splitkey == 0) {
            $this->db->where("FIND_IN_SET(".$splitvalue.",w_card_style)!=",0);
            }
            else{
              $this->db->or_where("FIND_IN_SET(".$splitvalue.",w_card_style)!=",0);
            }
          }

ChildClick Listner上的android可扩展ListView无法正常工作
