Question

我有数据库工作正常。我使用edittext将数据插入到database.data插入是很好的工作。但与edittext如何我可以通过code.anyone来帮助我存储我的数据库的价值。提前谢谢。

这是我的dbhelper类。

public class FoodDbHelper extends SQLiteOpenHelper {
private static final String DATABASE_NAME = "PKFM.DB";
private static final int DATABASE_VERSION = 1;
private static final String CREATE_QUERY =
        "CREATE TABLE "+ Food.NewDishInfo.TABLE_NAME+"("
                + Food.NewDishInfo.DISH_NAME+" TEXT NOT NULL,"
                + Food.NewDishInfo.DISH_QUANTITY+" TEXT NOT NULL,"
                + Food.NewDishInfo.DISH_CALORIE+" INTEGER,"
                + Food.NewDishInfo.DISH_FAT+" TEXT NOT NULL,"
                + Food.NewDishInfo.DISH_PROTEIN+" TEXT NOT NULL,"
                + Food.NewDishInfo.DISH_SUGAR+" TEXT NOT NULL,"
                + Food.NewDishInfo.DISH_CARBOHYDRATES+" TEXT NOT NULL);";
public FoodDbHelper(Context context)
{
    super(context,DATABASE_NAME,null,DATABASE_VERSION);
    Log.e("DATABASE OPERATION","Database created / opened...");
}
@Override
public void onCreate(SQLiteDatabase db) {
    db.execSQL(CREATE_QUERY);
    Log.e("DATABASE OPERATION","Table created...");


}
public void addInformations(String name ,String quantity, Integer calorie, String fat ,
                            String protein,String sugar,String carbohydrates, SQLiteDatabase db){


    ContentValues contentValues = new ContentValues();
    contentValues.put(Food.NewDishInfo.DISH_NAME,name);
    contentValues.put(Food.NewDishInfo.DISH_QUANTITY,quantity);
    contentValues.put(Food.NewDishInfo.DISH_CALORIE,calorie);
    contentValues.put(Food.NewDishInfo.DISH_FAT,fat);
    contentValues.put(Food.NewDishInfo.DISH_PROTEIN,protein);
    contentValues.put(Food.NewDishInfo.DISH_SUGAR,sugar);
    contentValues.put(Food.NewDishInfo.DISH_CARBOHYDRATES,carbohydrates);

    db.insert(Food.NewDishInfo.TABLE_NAME, null, contentValues);


    Log.e("DATABASE OPERATION","one row inserted...");
}

我做了这样的事情，但没有插入数据

foodDbHelper = new FoodDbHelper(context);
    foodDbHelper.addInformations("Paratha", "1 piece", 260,"8.99 g","5.16 g","2.18 g","38.94 g",sqLiteDatabase);

不太确定你在寻找什么...... 您还希望如何获取存储到数据库中的信息？

这似乎更像是一个用户体验问题，而不是“如何”＃。正确的方法似乎已经包含在你的代码中，无论你想要什么字符串都可以推送。
