setText in CountDownTimer in ListView Adapter in Android?

Question

I am working in an Wedding App where I am maintaining a ListView of feeds.

The First element of my Feed Screen ListView is having a TIMER for the CURRENT DATE to the WEDDING DATE.

As I have taken the TIMER in a ListView, it getting hard to update the text of the TextView in onTick() method.

Wedding time is only visible in the first element of the list view.

_time = new CountDownTimer(WeddingTimeinMiliSec, 5000) {
                String showDate;
                long subtractvalue = 1000;

                Calendar currentTime = Calendar.getInstance();

                public void onTick(long millisUntilFinished) {
                    long diff = Day.getTimeInMillis() - currentTime.getTimeInMillis();
                    diff-=subtractvalue;
                    StringBuffer text = new StringBuffer("");
                    if (diff > DAY) {
                        //showDate = showDate+""+(diff / DAY)+("days ");
                        final long dif = diff;
                        if(holder!=null && holder._dayRespTextView!=null){
                            runOnUiThread(new Runnable() {
                                @Override
                                public void run() {
                                    holder._dayRespTextView.setText(String.valueOf((dif / DAY)));
                                }
                            });
                        }
                        text.append(diff / DAY).append(" days ");
                        diff %= DAY;
                    }
                    if (diff > HOUR) {
                        //  showDate = showDate+""+(diff / HOUR)+("hours ");
                        final long dif = diff;
                        if(holder!=null && holder._hoursRespTextView!=null){
                            runOnUiThread(new Runnable() {
                                public void run() {
                                    holder._hoursRespTextView.setText(String.valueOf((dif / HOUR)));
                                }
                            });
                        }
                        text.append(diff / HOUR).append(" hours ");
                        diff %= HOUR;
                    }
                    if (diff > MINUTE) {
                        //  showDate = showDate+""+(diff / MINUTE)+("minutes ");
                        final long dif = diff;
                        if(holder!=null && holder._minRespTextView!=null){
                            runOnUiThread(new Runnable() {
                                public void run() {
                                    holder._minRespTextView.setText(String.valueOf((dif / MINUTE)));
                                }
                            });
                        }

                        text.append(diff / MINUTE).append(" minutes ");
                        diff %= MINUTE;
                    }
                    if (diff > SECOND) {
                        //  showDate = showDate+""+(diff / SECOND)+("seconds ");
                        final long dif = diff;
                        if(holder!=null && holder._secRespTextView!=null){
                            runOnUiThread(new Runnable() {
                                public void run() {
                                    holder._secRespTextView.setText(String.valueOf((dif / SECOND)));
                                }
                            });                         
                        }

                        text.append(diff / SECOND).append(" seconds ");
                        diff %= SECOND;
                    }
                    /*_tvTime.setText(""+WeddingTime);*/    
                    showDate="";
                    subtractvalue+=1000;
                    notifyDataSetChanged();
                }
                public void onFinish() {

                }
            }.start();

This is my CountDownTimer code that I am using inside the CONSTRUCTOR of my ListView ADAPTER.

How can I update the text of the TextViews in the ListView's first element on onTick event. Please suggest me.

try this..

/**
* ADDING HEADER LAYOUT TO THE LISTVIEW
*/

View headerView = ((LayoutInflater)PostScreen.this.getSystemService(PostScreen.this.LAYOUT_INFLATER_SERVICE)).
inflate(R.layout.header_layout, null, false);
textview = (TextView)headerView.findViewById(R.id.countdown_tv);


 _time = new CountDownTimer(WeddingTimeinMiliSec, 5000) {
String showDate;
long subtractvalue = 1000;

Calendar currentTime = Calendar.getInstance();
public void onTick(long millisUntilFinished) {
long diff = Day.getTimeInMillis() - currentTime.getTimeInMillis();
diff-=subtractvalue;
StringBuffer text = new StringBuffer("");
if (diff > DAY) {
//showDate = showDate+""+(diff / DAY)+("days ");
final long dif = diff;
dayThread = String.valueOf((dif / DAY));
text.append(diff / DAY).append(" days ");
diff %= DAY;
}
if (diff > HOUR) {
final long dif = diff;
hoursThread = String.valueOf((dif / HOUR));
text.append(diff / HOUR).append(" hours ");
diff %= HOUR;
}
if (diff > MINUTE) {
final long dif = diff;
minThread = String.valueOf((dif / MINUTE));
text.append(diff / MINUTE).append(" minutes ");
diff %= MINUTE;
}
if (diff > SECOND) {
final long dif = diff;
secThread = String.valueOf((dif / SECOND));
text.append(diff / SECOND).append(" seconds ");
diff %= SECOND;
}
showDate="";
subtractvalue+=1000;

String dateText = "<font color="+countDown_TextColor+">"+dayThread+
" DIAS </font> <font color="+countDown_TextColor+">"+hoursThread+
" HOURAS </font><font color="+countDown_TextColor+">"+minThread+" MIN</font>" +
"<font color="+countDown_TextColor+">"+secThread+" MIN</font>";
textview.setText(Html.fromHtml(dateText));
}

public void onFinish() {

}
}.start();
