我正面臨有關sqlite數據庫的問題。我想將數據保存在數據庫中。 KEY_LATITUDE和KEY_LONGITUDE分別從info.getLatitude()和info.getLongitude()獲得空值。但info.getLongitude()和info.getLatitude()分別爲12.99999和50.9999。如何在android中的sqlite中保存double數據類型值
private static final String KEY_ID = "id";
private static final String KEY_EventName = "event_name";
private static final String KEY_Description = "description";
private static final String KEY_Location = "location";
private static final String KEY_Date = "date";
private static final String KEY_Time = "time";
private static String KEY_LATITUDE ;
private static String KEY_LONGITUDE ;
addinfo函數將數據保存到數據庫中。
public void addInfo(Event info) {
SQLiteDatabase db = this.getWritableDatabase();
ContentValues values = new ContentValues();
values.put(KEY_EventName, info.getEventName());
values.put(KEY_Location, info.getLocationName());
values.put(KEY_Description, info.getDescription());
values.put(KEY_Date, info.getDate());
values.put(KEY_Time, info.getTime());
values.put(KEY_LATITUDE, info.getLatitude()); // it return Double
// value.i.e 12.999999
values.put(KEY_LONGITUDE, info.getLongitude()); // it return Double
// value.i.e 12.999999
db.insert(TABLE_EVENT_DATA, null, values);
db.close(); // Closing database connection
}
