私はアンドロイドスタジオでプロジェクトを進めています。データベースを作成する必要があります。データベースの仕組みを理解していますが、作成方法を理解できません。私のプロジェクトでは、データベースのテーブルを作成するクラスDataBaseHandlerを取得しました。アンドロイドプロジェクトのデータベースを作成する
public class DatabaseHandler extends SQLiteOpenHelper {
//DataBase name
public static final String TABLE_PERSON = "person";

だから、私は、データベースを作成します（どこで？他のクラスで）とどのように私はこれらのテーブルを埋めるんどのようにここで質問。私は私の質問があいまいだと知っていますが、私は一日中検索しましたが、私は諦めています。または、良いチュートリアルへのリンクがあります。
私はこのメソッドを使い始めました。誰が自分のデータベースにusersメソッドを埋めなければならないのですか。しかし、私が以前に述べたように、データベースは作成されません。あなたが私を助けることができる場合
public static void createPerson(User user,SQLiteDatabase db){
db.execSQL("insert into"+TABLE_PERSON+"values ("+user.getLoginStr()+", "+user.getPlaceStr()+", "+user.getPlaceStr()+", "+user.getFirstNameStr()+", "+user.getNameStr()+", "+user.getBirthdayStr()+", "+user.getLanguageStr()+", "+user.getHairStr()+", "+user.getEyesStr()+", "+user.getPassword()+", "+user.getDescriptionStr()+", "+user.getGenderStr()+", "+user.getOrientationStr());
}
はあなたにたくさんありがとう、またはあなたは私
