Question

您好我已创建CustomListView复选框。当我点击第一个项目时，它也会自动启用第三个项目。怎么解决？

holder.orderCheckBox.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View v) {                      
   if(((CheckBox)v).isChecked()) {
     checkboxstate[position]=true;  
     if(observationDetailsList.get(position).LaboratoryUid.toString().equalsIgnoreCase(GlobalVariables.UUIDEmpty.toString()))
     {
        displayWarning();
     }       
     patientOrderList.add(orderDetailsList.get(position));
     patientObservationList.add(observationDetailsList.get(position));

  } else {
    checkboxstate[position]=false;
    patientOrderList.remove(orderDetailsList.get(position));
    patientObservationList.remove(observationDetailsList.get(position));
  }
 }
});

以下是处理此

的完整适配器类

我正在使用toogle按钮，并且您可以使用相同的复选框来维护复选框的状态

public class SettingsListAdapter extends BaseAdapter implements 
{
    private LayoutInflater mInflater;
    private DealsSTRUC[] setings_Adapt_Catagories;
    Context mContext;
    String isNotificationEnnabled;

    public SettingsListAdapter( Context context, DealsSTRUC[] catagories ,String isEnnabled)
        {
            mContext = context;
            setings_Adapt_Catagories = catagories;
            mInflater = LayoutInflater.from(context);
            isNotificationEnnabled=isEnnabled;
        }

    @Override
    public int getCount()
        {
            return setings_Adapt_Catagories.length;
        }

    @Override
    public Object getItem(int arg0)
        {
            return null;
        }

    @Override
    public long getItemId(int position)
        {
            return 0;
        }

    @Override
    public View getView(final int position, View convertView, ViewGroup parent)
        {
            SettingsAdptorViewHolder holder;
            if (convertView == null)
                {
                    convertView = mInflater.inflate(R.layout.adapter_settingslist, null);
                    holder = new SettingsAdptorViewHolder();
                    holder.settings_catagory = (TextView) convertView.findViewById(R.id.settings_lable_text);
                    holder.settings_list_checkbox = (ToggleButton) convertView.findViewById(R.id.settings_checkbox);
                    holder.settings_list_checkbox.setOnClickListener(new OnClickListener()
                        {
                            @Override
                            public void onClick(View v)
                                {
                                    ToggleButton cb = (ToggleButton) v;
                                    if (cb.isChecked() == true)
                                        {
                                            setings_Adapt_Catagories[position].setStatus("true");
                                        }
                                    else
                                        {

                                        }
                                }
                        });
                    convertView.setTag(holder);
                }
            else
                {
                    holder = (SettingsAdptorViewHolder) convertView.getTag();
                }
            if(setings_Adapt_Catagories[position].getStatus().equals("true")&&isNotificationEnnabled.equals("on"))
                {
                    holder.settings_list_checkbox.setChecked(true);                     
                }
            else if(setings_Adapt_Catagories[position].getStatus().equals("false"))
                {
                    holder.settings_list_checkbox.setChecked(false);
                }               
            holder.settings_catagory.setText(setings_Adapt_Catagories[position].getDealName());
            return convertView;
        }

    class SettingsAdptorViewHolder
        {
            TextView settings_catagory;
            ToggleButton settings_list_checkbox;
        }
}
