您好，我有一个不响应的 gridview 的客户适配器
setOnItemClickListener。
我已经查看了这个问题，但没有任何帮助：
https://code.google.com/p/android/issues/detail?id=3414
http://www.androidhive.info/2012/02/android-custom-listview-with-image-and-text/
我在我的 logcat 上测试了我的响应，但是当我单击 gridview 中的项目时我没有得到任何响应。
这是我的适配器代码：
public class GridCellAdapter extends BaseAdapter{
private static final String tag = "GridCellAdapter";
private final Context _context;
private final List<String> list;
private static final int DAY_OFFSET = 1;
private final String[] weekdays = new String[] { "Sun", "Mon", "Tue",
"Wed", "Thu", "Fri", "Sat" };
private final String[] months = { "January", "February", "March",
"April", "May", "June", "July", "August", "September",
"October", "November", "December" };
private final int[] daysOfMonth = { 31, 28, 31, 30, 31, 30, 31, 31, 30,
31, 30, 31 };
private final int month, year;
private int daysInMonth, prevMonthDays;
private int currentDayOfMonth;
private int currentWeekDay;
public String lastDateString;
// Days in Current Month
public GridCellAdapter(Context context, int textViewResourceId,
int month, int year) {
super();
this._context = context;
this.list = new ArrayList<String>();
this.month = month;
this.year = year;
//Log.d(tag, "==> Passed in Date FOR Month: " + month + " "
// + "Year: " + year);
Calendar calendar = Calendar.getInstance(Locale.ENGLISH);
setCurrentDayOfMonth(calendar.get(Calendar.DAY_OF_MONTH));
setCurrentWeekDay(calendar.get(Calendar.DAY_OF_WEEK));
//Log.d(tag, "New Calendar:= " + calendar.getTime().toString());
//Log.d(tag, "CurrentDayOfWeek :" + getCurrentWeekDay());
//Log.d(tag, "CurrentDayOfMonth :" + getCurrentDayOfMonth());
// Print Month
printMonth(month, year);
}

return months[i];
}

}
public Object getItem(int position) {

return list.size();
}
/**

private void printMonth(int mm, int yy) {
//Log.d(tag, "==> printMonth: mm: " + mm + " " + "yy: " + yy);

int trailingSpaces = 0;
int daysInPrevMonth = 0;
int prevMonth = 0;
int prevYear = 0;
int nextMonth = 0;

}
int currentWeekDay = cal.get(Calendar.DAY_OF_WEEK) - 1;
trailingSpaces = currentWeekDay;
if (cal.isLeapYear(cal.get(Calendar.YEAR)) && mm == 2) {
++daysInMonth;
}

}
}

}
我的 onCreate 中的代码：
calendarView = (GridView) this.findViewById(R.id.calendar);
adapter = new GridCellAdapter(getApplicationContext(),
R.id.calendar_day_gridcell, month, year);
adapter.notifyDataSetChanged();
calendarView.setAdapter(adapter);
calendarView.setOnItemClickListener(this);
监听器：
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
Log.i("position", arg2+"");
}
