SQLite：将数组字符串插入表中未增加 ID

Question

尝试将字符串数组插入表中，但插入的 id 没有增加，并且第一个字符串已插入。我对 id 使用自动增量？

表创建

//Multi Farm Table
String CREATE_MULTI_FARM_TABLE = "CREATE TABLE " + TABLE_MULTI_FARM + "(" +
        KEY_MULTI_FARM_ID + " INTEGER PRIMARY KEY AUTOINCREMENT, " +
        KEY_MULTI_FARM_FARM_NAME + " TEXT" + ")";
db.execSQL(CREATE_MULTI_FARM_TABLE);

插入记录函数

//Add Multi Farm
public void addMultiFarm(MultiFarmModel multiFarm) {
    SQLiteDatabase db = this.getWritableDatabase();
    ContentValues values = new ContentValues();
    values.put(KEY_MULTI_FARM_ID, multiFarm.getId());
    values.put(KEY_MULTI_FARM_FARM_NAME, multiFarm.getFarmName());
    //Insert Record
    Log.e("StringInsertId", "" + db.insert(TABLE_MULTI_FARM, null, values));
    db.close();
}

类中的函数

public MultiFarmModel(String farmName){
    this.farmName = farmName;
}

插入代码

String smsContent = "InsertToTable A|B|C|D|E";
DBHandler db = new DBHandler(context);
                smsContent = smsContent.substring(smsContent.indexOf(" ")+1);
                String[] string = smsContent.split("\\|");
                db.deleteAllMultiFarmRecord();
                for (String s : string) {
                    Log.e("StringToInsert", s + " ? ");
                    db.addMultiFarm(new MultiFarmModel(s));
                }
            }

日志控制台

E/String Number: A|B|C|D|E
E/StringToInsert: A ? 
E/StringInsertId: 0
E/StringToInsert: B ? 
E/StringInsertId: -1
E/StringToInsert: C ? 
E/StringInsertId: -1
E/StringToInsert: D ? 
E/StringInsertId: -1
E/StringToInsert: E ? 
E/StringInsertId: -1

删除此 KEY_MULTI_FARM_ID 行，因为它是自动递增列...您传递的值相同，这就是它抛出错误的原因

public void addMultiFarm(MultiFarmModel multiFarm) {
    SQLiteDatabase db = this.getWritableDatabase();
    ContentValues values = new ContentValues();
   // values.put(KEY_MULTI_FARM_ID, multiFarm.getId()); 
    values.put(KEY_MULTI_FARM_FARM_NAME, multiFarm.getFarmName());
    //Insert Record
    Log.e("StringInsertId", "" + db.insert(TABLE_MULTI_FARM, null, values));
    db.close();
