Question

我的简单帐簿代码存在一些问题。

我想在点击保存按钮时插入一行。

我检查了我的表格已成功创建。

save.setOnClickListener(new Button.OnClickListener(){

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub

            mDbOpenHelper.open();

            try{
            mDbOpenHelper.insertColumn(
                    rButton, 
                    mEditTexts[1].getText().toString().trim(), 
                    spinnerSelected, 
                    mEditTexts[0].getText().toString().trim());
            }catch(Exception e){
                Log.d("TAG","error");
            }

            mDbOpenHelper.close();
            mCursor.close();

        }

    });

insertColumn（）

// Insert DB
        public long insertColumn(String cashORcard, String amount, String category, String detail){
            mDB = mDBHelper.getWritableDatabase();
            ContentValues values = new ContentValues();
            values.put(Database.CreateDB.CASH, cashORcard);
            values.put(Database.CreateDB.AMOUNT, amount);
            values.put(Database.CreateDB.CATEGORY, category);
            values.put(Database.CreateDB.DETAIL, detail);

            return mDB.insert(Database.CreateDB.TABLENAME, null, values);

        }

定义我的数据库表

public class Database {

public static final class CreateDB implements BaseColumns{
    public static String firstCash="0";
    public static String firstAccount="0";
    public static String allMoney="0";
    public static final String CASH="cash";
    public static final String CATEGORY="category";
    public static final String DETAIL="detail";
    public static final String AMOUNT="0";
    public static final String ID="0";
    public static final String TABLENAME="Accountbook";
    public static final String CREATE=
            "CREATE TABLE "+TABLENAME
            +" ( _id integer primary key autoincrement, "
            +" CASH text not null , "
            +" AMOUNT text not null , "
            +" CATEGORY text not null , "
            +" DETAIL text , "
            +" firstCash text not null , "
            +" firstAccount text not null , "
            +" allMoney text not null );";  
    }
}

需要更多代码，请告诉我！谢谢！

Answer 1

首先，您要插入行而非列。

然后，日志中的错误非常清楚

android.database.sqlite.SQLiteException: near "0": ... INSERT INTO Accountbook(cash,detail,category,0) VALUES (?,?,?,?) ...

您试图将值插入无效的列名称： 0

Answer 2

public static final String AMOUNT="0"

这应该是

public static final String AMOUNT="AMOUNT"

您尝试插入名为“0”

的列的结果

Answer 3

请参阅错误0=567。您的列名称位于integer类型中。所以这是错误的。 Colomn名称应该有效。所以，试试以下

public static final String CREATE=
        "CREATE TABLE "+TABLENAME
        +" (_id integer primary key autoincrement, "
        + CASH +" text not null , "
        + AMOUNT+" text not null , "
        + CATEGORY+" text not null , "
        + DETAIL+" text , "
        + firstCash+" text not null , "
        + firstAccount+" text not null , "
        + allMoney+" text not null );";

而不是这个

public static final String CREATE=
        "CREATE TABLE "+TABLENAME
        +" ( _id integer primary key autoincrement, "
        +" CASH text not null , "
        +" AMOUNT text not null , "
        +" CATEGORY text not null , "
        +" DETAIL text , "
        +" firstCash text not null , "
        +" firstAccount text not null , "
        +" allMoney text not null );";

同时更改

firstCash,firstAccount,allMoney,AMOUNT varibales values to be valid string.

像

public static String firstCash="firstCash";
public static String firstAccount="firstAccount";
public static String allMoney="allMoney";
public static final String AMOUNT="AMOUNT";

为什么因为列名应该有效。

我希望这会对你有所帮助。

Answer 4

您已将mEditTexts[0].getText().toString().trim()的值传递给字符串详细信息。检查字符串详细信息的值和ID Database.CreateDB.DETAIL。如果它显示“0”那么它应该是“细节”。

Answer 5

尝试更改插入查询，如下所示：

您还需要传递其他剩余列firstCash,firstAccount,allMoney值，因为在您的创建表查询中，您已将其属性定义为NOT NULL。

public long insertColumn(String cashORcard, String amount, String category, String detail,String cashValue,String AccountVal,String money){
        mDB = mDBHelper.getWritableDatabase();
        ContentValues values = new ContentValues();
        values.put(Database.CreateDB.CASH, cashORcard);
        values.put(Database.CreateDB.AMOUNT, amount);
        values.put(Database.CreateDB.CATEGORY, category);
        values.put(Database.CreateDB.DETAIL, detail);
        values.put(Database.CreateDB.firstCash, cashValue);
        values.put(Database.CreateDB.firstAccount, AccountVal);
        values.put(Database.CreateDB.allMoney, money);
        return mDB.insert(Database.CreateDB.TABLENAME, null, values);
    }
