Настраиваемый просмотр списка NullPointerException

У меня есть пользовательский SimpleCursor listView и хронометр. Я пытаюсь сделать, когда Chronometer (таймер) равен 00:10. Нарисуйте цвет строки, но его выброс NullPointerException.

Спасибо U за помощь Вот код:

public class ListViewcursorActivity extends ListActivity {
/** Called when the activity is first created. */
Chronometer timer;
ListView lvItems;
SimpleCursorAdapter colours;
private testDBAdapter thisTestDBAdapter;
LinearLayout[] Row;
View[] v;
@Override
public void onCreate(Bundle savedInstanceState) {

    thisTestDBAdapter = new testDBAdapter(this);
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    lvItems =getListView();fillData();

    timer = (Chronometer)findViewById(R.id.chronometer1);

    timer.setBase(android.os.SystemClock.elapsedRealtime());
    timer.start();

     Row =new LinearLayout[lvItems.getCount()];
     v = new View[lvItems.getCount()];
    for(int i=0;i<lvItems.getChildCount();i++) {
        v[i] =lvItems.getChildAt(i);
        Row[i] = (LinearLayout)v[i].getParent();    
    }
    timer.setOnChronometerTickListener(new Chronometer.OnChronometerTickListener() {

        public void onChronometerTick(Chronometer chronometer) {
            // TODO Auto-generated method stub
            for(int i=0;i<lvItems.getChildCount();i++){

            //  TextView child =(TextView)Row[i].getChildAt(0);
                if(  chronometer.getText().toString().equalsIgnoreCase("Timer: 00:10")){

                    try {
                        Row[1].setBackgroundColor(Color.RED);
                    } catch (NullPointerException e) {
                        // TODO Auto-generated catch block
                        Toast.makeText(ListViewcursorActivity.this, e.toString(), Toast.LENGTH_SHORT).show();
                    }
                }

            }
    }
    });
}

Проблема заключается в следующем://TextView child = (TextView) Row [i].getChildAt(0); и Row [1].setBackgroundColor(Color.RED);
