填充数据库时出错：字段“价格”不是“ Android Studio版本：3.4.2”

Question

我尝试创建一个数据库并尝试填充它，但是字段“ price”不是错误，我显示的代码以及常量Util.KEY_PRICE的状态不是这样，请帮助boloe谢谢。我第一次使用Android Studio中的数据库在教室中通过视频进行操作，但是没有办法。AndroidStudio版本：3.4.2

尝试添加此

SQLiteDatabase db = databaseHandler.getWritableDatabase(); in
MainActivity.java in onCreate ,don't work

    public class DatabaseHandler extends SQLiteOpenHelper {
        public DatabaseHandler(Context context) {
            super(context, Util.DATABASE_NAME, null, Util.DATABASE_VERSION);
        }

        @Override
        public void onCreate(SQLiteDatabase db) {
            //SQL - structured query language (язык структурированных запросов)
            String CREATE_CARS_TABLE = "CREATE TABLE "+Util.TABLE_NAME+"("
                    + Util.KEY_ID + " INTEGER PRIMARY KEY,"
                    + Util.KEY_NAME + " TEXT,"
                    + Util.KEY_PRICE + " TEXT" + ")";
            db.execSQL(CREATE_CARS_TABLE);

            //public static final String KEY_PRICE = "price";
        }

MainActivity.java：

import androidx.appcompat.app.AppCompatActivity;

import android.database.sqlite.SQLiteDatabase;
import android.os.Bundle;
import android.util.Log;

import java.util.List;

import Data.DatabaseHandler;
import Model.Car;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        DatabaseHandler databaseHandler = new DatabaseHandler(this);
        //SQLiteDatabase db = databaseHandler.getWritableDatabase();
        databaseHandler.addCar(new Car("Toyota","30 000 $"));
        databaseHandler.addCar(new Car("Opel","25 000 $"));
        databaseHandler.addCar(new Car("Mersedes","50 000 $"));
        databaseHandler.addCar(new Car("KIA","28 000 $"));
        databaseHandler.addCar(new Car("Mazda","30 000 $"));
        databaseHandler.addCar(new Car("Honda","25 000 $"));
        databaseHandler.addCar(new Car("Skoda","50 000 $"));
        databaseHandler.addCar(new Car("Hundai","28 000 $"));
        List<Car> carList = databaseHandler.getAllCars();
        for (Car car : carList){
            Log.d("CarInfo : ","ID " + car.getId()+ ", name " + car.getName()+
                    ",price " + car.getPrice());
        }

    }
}
