唯一约束失败，SQLite，Java

我有一个包含addPub和getAllpub方法的数据库：

         import android.content.ContentValues;
    import android.content.Context;
    import android.database.Cursor;
    import android.database.sqlite.SQLiteDatabase;
    import android.database.sqlite.SQLiteOpenHelper;

    import java.util.ArrayList;
    import java.util.List;


public class Database extends SQLiteOpenHelper{
public static final int DATABASE_VERSION = 1;
public static final String DATABASE_NAME = "Pubs.db";
public static final String DATABASE_TABLE = "pubsTable";
public static final String COL_1 = "ID";
public static final String COL_2 = "NAME";
public static final String COL_3 = "LAT";
public static final String COL_4 = "LNG";
public static final String COL_5 = "OPEN";
public static final String COL_6 = "CLOSE";
public static final String COL_7 = "PUB";
public static final String COL_8 = "COCKTAIL";
public static final String COL_9 = "BEER";
public static final String COL_10 = "FOOD";
public static final String COL_11 = "DART";
public static final String COL_12 = "POOL";
public static final String COL_13 = "MUSIC";
public static final String COL_14 = "SPORT";
public static final String COL_15 = "OUTSIDE";
public static final String COL_16 = "PAY";
public static final String COL_17 = "QUIZ";
public static final String COL_18 = "PHONE";


public Database(Context context) {
    super(context, DATABASE_NAME, null, DATABASE_VERSION);
}

@Override
public void onCreate(SQLiteDatabase db) {
    String CREATE_CONTACTS_TABLE = "CREATE TABLE" + " " +DATABASE_TABLE + "("
            + COL_1 +" " +"INTEGER PRIMARY KEY AUTOINCREMENT,"
            + COL_2 +" " + "TEXT,"
            + COL_3 +" " + "TEXT,"
            + COL_4 +" " + "TEXT,"
            + COL_5 +" " + "TEXT,"
            + COL_6 +" " + "TEXT,"
            + COL_7 +" " + "TEXT,"
            + COL_8 +" " + "TEXT,"
            + COL_9 +" " + "TEXT,"
            + COL_10 +" " + "TEXT,"
            + COL_11 +" " + "TEXT,"
            + COL_12 +" " + "TEXT,"
            + COL_13 +" " + "TEXT,"
            + COL_14 +" " + "TEXT,"
            + COL_15 +" " + "TEXT,"
            + COL_16 +" " + "TEXT,"
            + COL_17 +" " + "TEXT,"
            + COL_18 +" " + "TEXT"
            + ")";
    db.execSQL(CREATE_CONTACTS_TABLE);
}

@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
    db.execSQL("DROP TABLE IF EXISTS " + DATABASE_TABLE);
    onCreate(db);
}

void addPub(Pub pub) {
    SQLiteDatabase db = this.getWritableDatabase();
    ContentValues values = new ContentValues();
    values.put(COL_1, pub.getID());
    values.put(COL_2, pub.getName());
    values.put(COL_3, pub.getLat());
    values.put(COL_4, pub.getLng());
    values.put(COL_5, pub.getOpen());
    values.put(COL_6, pub.getClose());
    values.put(COL_7, pub.getPub());
    values.put(COL_8, pub.getCocktail());
    values.put(COL_9, pub.getBeer());
    values.put(COL_10, pub.getFood());
    values.put(COL_11, pub.getDart());
    values.put(COL_12, pub.getPool());
    values.put(COL_13, pub.getMusic());
    values.put(COL_14,pub.getSport());
    values.put(COL_15, pub.getOutside());
    values.put(COL_16, pub.getPay());
    values.put(COL_17, pub.getQuiz());
    values.put(COL_18, pub.getPhone_number());

    db.insert(DATABASE_TABLE, null, values);
    db.close();
}

public List<Pub> getAllPubs() {
    List<Pub> pubList = new ArrayList<>();
    String selectQuery = "SELECT  * FROM " + DATABASE_TABLE;

    SQLiteDatabase db = this.getWritableDatabase();
    Cursor cursor = db.rawQuery(selectQuery, null);
    if (cursor.moveToFirst()) {
        do {
            Pub pub = new Pub();
            pub.setID(Integer.parseInt(cursor.getString(0)));
            pub.setName(cursor.getString(1));
            pub.setLat(cursor.getString(2));
            pub.setLng(cursor.getString(3));
            pub.setOpen(cursor.getString(4));
            pub.setClose(cursor.getString(5));
            pub.setPub(cursor.getString(6));
            pub.setCocktail(cursor.getString(7));
            pub.setBeer(cursor.getString(8));
            pub.setFood(cursor.getString(9));
            pub.setDart(cursor.getString(10));
            pub.setPool(cursor.getString(11));
            pub.setMusic(cursor.getString(12));
            pub.setSport(cursor.getString(13));
            pub.setOutside(cursor.getString(14));
            pub.setPay(cursor.getString(15));
            pub.setQuiz(cursor.getString(16));
            pub.setPhone_number(cursor.getString(17));
            pubList.add(pub);
        } while (cursor.moveToNext());
    }
    return pubList;
}

}

但是，当我尝试运行添加函数时，如：

Database db = new Database(this);
    db.addPub( new Pub(1,"The Old Queen's Head","53.3809646","-1.4631316","10:00","23:00","p","0","1","1","0","0","1","0","1","0","0","07983559073"));

我得到这个错误：

E/SQLiteDatabase﹕ Error inserting OUTSIDE=1 PUB=p PHONE=07983559073 BEER=1 COCKTAIL=0 LNG=-1.4631316 NAME=The Old Queen's Head ID=1 CLOSE=23:00 LAT=53.3809646 SPORT=0 DART=0 QUIZ=0 OPEN=10:00 PAY=0 MUSIC=1 FOOD=1 POOL=0

我不知道原因是什么以及如何编辑我的代码。

我认为您已经将pubsTable.ID定义为主键，并且它已经包含1，因此您必须在添加新Pub时输入唯一ID。

无需添加

值。put（COL_1，Pub.getID（））

在您的

addPub（Pub-Pub）

方法中，因为您为

COL\u 1

放置了

INTEGER主键AUTOINCREMENT

，所以COL\u 1的id将自动生成并自动递增

在运行函数时，只需添加其他参数，无需添加COL_1参数，因此可以按如下方式调用函数-

`
db.addPub( newPub("TheOldQueen'sHead","53.3809646","1.4631316","10:00","23:00","p","0","1","1","0","0","1","0","1","0","0","07983559073"));`

省略语句

values.put（COL_1，pub.getID（））来自
addPub（Pub-Pub）


我希望有帮助

只需确保在进行所需更改后清除手机设置中的应用程序数据。
可能您已经在数据库中有ID等于1的记录。
`
db.addPub( newPub("TheOldQueen'sHead","53.3809646","1.4631316","10:00","23:00","p","0","1","1","0","0","1","0","1","0","0","07983559073"));`
