I have a sqlite database for saving name, address, category, latitudeandlongitude. In activity(1) i construct a listview. I have been able to retrieve data name for show in the listview, If the list is clicked it will open activity(2) which will showing data name, address, category and at the bottom there a map. I have been able to retrieve name, address and category in Activity(2) but i am confused to retrieve latitude and longitude for use to put marker in the map.
This my database class:
public class DB_Restoran extends SQLiteOpenHelper {final static String DB_NAME = "db_restoran";public DB_Restoran(Context context) { super(context, DB_NAME, null, 1); //Todo auto}@Overridepublic void onCreate(SQLiteDatabase db) { String sql = "CREATE TABLE IF NOT EXISTS restoran(_id INTEGER PRIMARY KEY AUTOINCREMENT, name TEXT, category TEXT, address TEXT, latitude DOUBLE, longitude DOUBLE)"; db.execSQL(sql); ContentValues values = new ContentValues(); values.put("_id", "1"); values.put("name", "RM. Kemang Raya"); values.put("category", "Umum"); values.put("address", "Jl.Endro Suratmin"); values.put("latitude", "-5.384402"); values.put("longitude", "105.295443"); db.insert("restoran", "_id", values); values.put("_id", "2"); values.put("nama", "RM.
