Android สอบถามเริ่องการดึงข้อมูล database มาแสดงแบบ listview

if (c.moveToFirst())
{
do {
// Extract the quake details.
Long datems = c.getLong(EarthquakeProvider.DATE_COLUMN);
String details;
details = c.getString(EarthquakeProvider.DETAILS_COLUMN);
Float lat = c.getFloat(EarthquakeProvider.LATITUDE_COLUMN);
Float lng = c.getFloat(EarthquakeProvider.LONGITUDE_COLUMN);
Double mag = c.getDouble(EarthquakeProvider.MAGNITUDE_COLUMN);
String link = c.getString(EarthquakeProvider.LINK_COLUMN);

Location location = new Location("dummy");
location.setLongitude(lng);
location.setLatitude(lat);

Date date = new Date(datems);
Quake q = new Quake(date, details, location, mag, link);
addQuakeToArray(q);
} while(c.moveToNext());
}
}
