我试图将新项目添加到我的数据库中，并且我收到此错误消息。我已经尝试了所有我能想到的东西。有什么我搞砸了吗？

这是实际提交数据并从editTexts和东西中获取数据的onClick方法。 

public void onSubmitClick(View view){

    productName = (EditText)findViewById(R.string.AddNew_editTextNameName);
    productPalletName = (EditText)findViewById(R.string.AddNew_editTextPalletName);
    productBrandName = (EditText)findViewById(R.string.AddNew_editTextBrandName);
    productDatePurchased = (EditText)findViewById(R.string.AddNew_editViewDatePurchasedName);
    productMisc = (EditText)findViewById(R.string.AddNew_editViewOtherName);

    productType = (Spinner)findViewById(R.string.AddNew_spinnerTypeName);
    productColor = (Spinner)findViewById(R.string.AddNew_spinnerColorCatName);


    ProductsDataSource datasource = new ProductsDataSource(this);
    datasource.open();

    if(isPallet){
        datasource.createProduct(productName.getText().toString(), productType.getId(), productColor.getId(),
                productBrandName.getText().toString(), productPalletName.getText().toString(), prodPath, swatchPath,
                productDatePurchased.getText().toString(), productMisc.getText().toString());
        datasource.close();
        Toast.makeText(this, "Creating New Product In Database", Toast.LENGTH_SHORT).show();
    } else{

        datasource.createProduct(productName.getText().toString(), productType.getSelectedItemPosition(), productColor.getSelectedItemPosition(),
                productBrandName.getText().toString(), null, prodPath, swatchPath,
                productDatePurchased.getText().toString(), productMisc.getText().toString());
        datasource.close();
        Toast.makeText(this, "Creating New Product In Database", Toast.LENGTH_SHORT).show();

    }

    productListActivity();
    finish();
}

这是实际创建项目的方法。我使用database.insert，我创建了SQL插件，试图解决我的问题。

public void createProduct(String productName, int productType, int productColor, String productBrand, 
            String productPalletName, String productProdPic, String productSwatchPic, String productDateOpened, String productMisc){

    ContentValues productValues = new ContentValues();
        //productValues.putNull(SQLiteHelper.colID);; //0 - written for order ease 
        productValues.put(SQLiteHelper.colName, productName); //1
        productValues.put(SQLiteHelper.colType, productType);//2
        productValues.put(SQLiteHelper.colPalletName, productPalletName); //3
        productValues.put(SQLiteHelper.colBrand, productBrand); //4
        productValues.put(SQLiteHelper.colColor,productColor);//5
        productValues.put(SQLiteHelper.colProdPic, productProdPic);//6
        productValues.put(SQLiteHelper.colSwatchPic, productSwatchPic); //7
        productValues.put(SQLiteHelper.colDate, productDateOpened); //8
        productValues.put(SQLiteHelper.colMisc, productMisc); //9

            // Inserting Row

            database.insert(productTable, null, productValues);
            database.close(); // Closing database connection 

    /*  database.execSQL("INSERT INTO "+ productTable + " (" + SQLiteHelper.colName + ","
        + SQLiteHelper.colType + "," + SQLiteHelper.colColor + "," + SQLiteHelper.colBrand + 
        "," + SQLiteHelper.colPalletName + "," + SQLiteHelper.colProdPic + "," + SQLiteHelper.colSwatchPic 
        + "," + SQLiteHelper.colDate + "," + SQLiteHelper.colMisc + ") VALUES ( '" + productName + "' , " + productType 
        + " , " + productColor + " ,'" + productBrand + "' , '" + productPalletName + "' , '" + productProdPic + "','" + 
        productSwatchPic + "'," + productDateOpened + ",'" + productMisc + "');");
        database.close();  */
    }

以下是它引用的另一种方法 - 它为列表视图提供了项目列表

public Cursor getAllProduct() {
        List<Product> productsList = new ArrayList<Product>();

        Cursor cursor = database.query(SQLiteHelper.productTable,
                allColumns, null, null, null, null, null);

        cursor.moveToFirst();
        while (!cursor.isAfterLast()) {
            Product product = cursorToProduct(cursor);
            productsList.add(product);
            cursor.moveToNext();        
            cursor.close();
        }
        return cursor;
    }

如果你想要它，这里是表创建

公共类SQLiteHelper扩展了SQLiteOpenHelper {

static final String dbName="MakeupMethodology";
static final String productTable="Products";
static final String colID="_id";
static final String colName="Product_Name";
static final String colType= "Type";
static final String colPalletName = "Pallet_Name";
static final String colBrand="Brand";
static final String colColor="Color";
static final String colProdPic="Prod_Pic";
static final String colSwatchPic = "Swatch_Pic";
static final String colDate = "Date_Purchased";
static final String colMisc = "Misc";
static final String CreateDatabase = 
        "CREATE TABLE IF NOT EXISTS " + productTable +" (" + colID + " INTEGER PRIMARY KEY AUTOINCREMENT , "+ colName + " TEXT NOT NULL , " 
        + colType + " TEXT NOT NULL, " + colPalletName + " TEXT , "+ colBrand + " TEXT NOT NULL, " + colColor + " TEXT NOT NULL, " 
        + colProdPic + " TEXT , " + colSwatchPic + " TEXT , " + colDate + " DATE NOT NULL , " + colMisc + " TEXT)";

private static final int DATABASE_VERSION = 1;

编辑：我在某处找到了（初学者:(）拼写错误以及我是如何得到新的错误消息。它已经更新了旧版本的地方

编辑：我再过几个小时就无法回答我自己的问题，所以我只是把它放在这里以防万一有人遇到类似的问题：

如果您的数据库表现得很奇怪并且您在模拟器上，则清理工作区并重新启动模拟器是不够的。删除整个过程并从SCRATCH开始（如果您已将sdcard图像附加到模拟器上，则可以保留它，只需从配置菜单中删除模拟器并创建一个新模拟器）

1 个答案:

答案 0 :(得分：0)

日志说明了一切：没有名为Product_Name的列。这应该告诉你：

  • 检查它是否真的存在。如果您使用sqlite在模拟器或root设备上进行测试，请尝试在shell上运行.schema Products

  • 如果您直接从eclipse安装，请确保每次运行应用时都更新数据库版本。除非应用检测到数据库版本已升级，否则表定义不会反映出来。
