我正在尝试在我的应用片段中生成警报列表。但我无法让它发挥作用。我已阅读很多关于自定义列表视图生成的文章，但无法弄清楚我的适配器有什么问题。 以下是我的片段..
public class AlarmListFragment extends MainFragment {
private ListView listViewAlarmList;
private ImageButton addAlarm;
private DBHandler dbObj;
private Alarm alarmCounter;
List<FinalAlarms> finalAlarmses = new ArrayList<FinalAlarms>();
public AlarmListFragment(){}
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState){
View rootView = inflater.inflate(R.layout.fragment_home_alarm,container,false);
listViewAlarmList = (ListView)rootView.findViewById(R.id.listViewAlarms);
addAlarm = (ImageButton)rootView.findViewById(R.id.imageButtonAddAlarm);
return rootView;
}
@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
finalAlarmses.add(new FinalAlarms(){{
this.setAlarm_title("pattoki");
this.setTimeFromString("16:08");
}});
finalAlarmses.add(new FinalAlarms(){{
this.setAlarm_title("Lahore");
this.setTimeFromString("18:10");
}});
FinalAlarmAdaptor finalAlarmAdaptor = new FinalAlarmAdaptor(getActivity(),finalAlarmses);
listViewAlarmList.setAdapter(finalAlarmAdaptor);
}
以下是我的适配器类
public class FinalAlarmAdaptor extends BaseAdapter {
LayoutInflater inflater;
List<FinalAlarms> alarm;
public FinalAlarmAdaptor(Activity context, List<FinalAlarms> items) {
super();
this.alarm = items;
this.inflater = (LayoutInflater) context.
getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
public int getCount() {
return alarm.size();
}
public Object getItem(int position) {
return alarm.get(position);
}
public long getItemId(int position) {
return 0;
}
private class Holder{
TextView title,time,date;
ToggleButton mon,tue, wed, thu, fri,sat,sun;
ToggleButton isOff;
ImageButton isShared;
}
public View getView(final int position, View convertView, ViewGroup parent) {
FinalAlarms item = alarm.get(position);
Holder holder;
View vi = convertView;
if (convertView == null) {
holder = new Holder();
vi = inflater.inflate(R.layout.customlist_row_reschedule_alarm, null);
holder.title = (TextView) vi.findViewById(R.id.textViewHomeTitle);
holder.time = (TextView) vi.findViewById(R.id.textViewHomeTime);
holder.date = (TextView)vi.findViewById(R.id.textViewHomeDate);
holder.mon = (ToggleButton) vi.findViewById(R.id.toggleBtnMon);
holder.tue = (ToggleButton) vi.findViewById(R.id.toggleBtnTues);
holder.wed = (ToggleButton) vi.findViewById(R.id.toggleBtnWed);
holder.thu = (ToggleButton) vi.findViewById(R.id.toggleBtnThu);
holder.fri = (ToggleButton) vi.findViewById(R.id.toggleBtnFri);
holder.sat = (ToggleButton) vi.findViewById(R.id.toggleBtnSat);
holder.sun = (ToggleButton) vi.findViewById(R.id.toggleBtnSun);
holder.isOff = (ToggleButton)vi.findViewById(R.id.toggleButtonHomeIsOff);
holder.isShared = (ImageButton)vi.findViewById(R.id.imageButtonHomeIsShared);
vi.setTag(holder);
}else{
holder = (Holder)vi.getTag();
}
holder.title.setText(item.getAlarm_title());
holder.time.setText(item.getTime().getHours()+":"+item.getTime().getMinute());
if(item.getWeek().isMon()) {
holder.mon.setChecked(true);
}
if(item.getWeek().isTues()){
holder.tue.setChecked(true);
}
if(item.getWeek().isWed()){
holder.wed.setChecked(true);
}
if(item.getWeek().isThu()){
holder.thu.setChecked(true);
}
if(item.getWeek().isFri()){
holder.fri.setChecked(true);
}
if(item.getWeek().isSat()){
holder.sat.setChecked(true);
}
if(item.getWeek().isSun()){
holder.sun.setChecked(true);
}
holder.isOff.setChecked(true);
return vi;
}
}
