我创建了一个带有倒数计时器的列表视图，结果第一次显示很好，但是当滚动列表时，它会被打乱，结果会出错。
适配器类：
public class EventsListAdapter extends BaseAdapter {
LayoutInflater inflater;
Activity context;
List<MyEvents> list;
long startTime = 0L;
long countUp;
String hrs = "00";
String mins = "00";
String secs = "00";
private MyCustomTimer myTimer;
public EventsListAdapter(Activity context, List<MyEvents> list) {
this.context = context;
inflater = context.getLayoutInflater();
this.list = list;
}
public void setActivityList(List<MyEvents> LoadList) {
list = LoadList;
}
public int getCount() {
return list.size();
}
public Object getItem(int position) {
return list.get(position);
}
public long getItemId(int position) {
return position;
}
static class ViewHolder {
TextView name;
}
public View getView(int position, View convertView, ViewGroup parent) {
MyEvents eventsData = list.get(position);
View rowView = convertView;
ViewHolder viewHolder;
if (rowView == null) {
LayoutInflater inflater = context.getLayoutInflater();
rowView = inflater.inflate(R.layout.likes_inflate, null);
viewHolder = new ViewHolder();
viewHolder.name = (TextView) rowView.findViewById(R.id.lblName);
if (eventsData.isStarted()){
myTimer = new MyCustomTimer(viewHolder.name);
myTimer.setTimer(eventsData.start_date);
}
rowView.setTag(viewHolder);
}else{
viewHolder = (ViewHolder) rowView.getTag();
}
return rowView;
}
}
CountDownTimer 类：
class MyCustomTimer{
TextView tv;
public MyCustomTimer(TextView tv) {
this.tv = tv;
}
void setTimer(final long time) {
new CountDownTimer(time, 1000) {
public void onTick(long millisUntilFinished) {
//Set formatted date to your TextView
tv.setText(Utilities.getDurationBreakdown(millisUntilFinished));
}
public void onFinish() {
tv.setText("Done!");
}
}.start();
}
}
这段代码有什么问题吗？请建议。
