onItemClick(AdapterView<?> parent, View view, int position, long id)

can someone explain what parent, and view does here? We don't really use them when we create this chunk of code:

public void onItemClick(AdapterView<?> parent, View view, int position, long id) { String dayOfTheWeek = mDays[position].getDayOfTheWeek(); String conditions = mDays[position].getSummary(); String highTemp = mDays[position].getTemperatureMax() + ""; String message = String.format("On %s the high will be %s and it will be %s", dayOfTheWeek, highTemp, conditions); Toast.makeText(DailyForecastActivity.this, message, Toast.LENGTH_LONG).show(); }

view is the item in the display that was clicked/tapped and parent is the ListView it's in (or other, like a Spinner). They are passed in case they are needed.
