``我正在使用SQLite数据库。我创建了两个表。第一个表是用户表,它已成功创建并插入。但在我的第二个表中也成功创建但没有插入。这是我的问题。感谢进步..

这是 OnClick 事件,这里尝试调用数据库类中存在的插入方法

public void onClick(View v) {
    String itemname;
    String price;
    int position;
    if(v.getId()==R.id.id_btn_submit){
        //insert the price into database
            itemname =mEditItemName.getText().toString();
            price =(mEditPrice.getText().toString());
            position=spinner.getSelectedItemPosition();

        if(itemname.isEmpty()){
            mEditItemName.setError("enter the item name");

        }else if(price.isEmpty()){
            mEditPrice.setError("pls enter the price");
        }else{
            dataBase=new DataBase(this);
            position=position+1;
            mItemId= dataBase.insertAll(itemname,price, String.valueOf(position));
        }
        mEditItemName.setText("");
        mEditPrice.setText("");
      Log.d("bucky ","succefully insert ");

    } 

这是插入方法

 public long insertAll(String itemname ,String price,String itemcategory){
    SQLiteDatabase sqLiteDatabase=databasehelper.getWritableDatabase();
    ContentValues content=new ContentValues();
    content.put(databasehelper.mITEMNAME, itemname);
    content.put(databasehelper.mITEMPRICE, price);
    content.put(databasehelper.mITEMCATEGORY, itemcategory);
    long id=sqLiteDatabase.insert(databasehelper.mTABLEMENUITEM,null,content);
    Log.d("bucky insert item", String.valueOf(id));
    return id;
}

创建语句和更新语句

 public class DataBaseHelper extends SQLiteOpenHelper{
    private final static String mDATABASENAME="foodpanta";
    private final static int mVERSION=9;
    private Context context;
    //user  information table
    private final static String mTABLEUSERDETAIL="userdetail";
    private final static String mUID="_id";
    private final static String mUSERNAME="username";
    private final static String mUSERMAIL="usermail";
    private final static String mUSERPASS="userpass";
    private final static String mUSERMOBILE="usermobile";
    private final static String mCREATETABLEUSER ="CREATE TABLE " + mTABLEUSERDETAIL +" ("+mUID+ " INTEGER PRIMARY KEY AUTOINCREMENT, " +mUSERNAME+" VARCHAR(255) NOT NULL, "+mUSERMAIL+" VARCHAR(255) NOT NULL, "+mUSERPASS+" VARCHAR(255) NOT NULL, "+mUSERMOBILE+" VARCHAR(255));";

    //Adding menu item table
    private final static String mTABLEMENUITEM="menuitem";
    private final static String mITEMID="_id";
    private final static String mITEMCATEGORY="item category";
    private final static String mITEMPRICE="itemprice";
    private final static String mITEMNAME="itemname";
    private final static String mCREATETABLEMENU="CREATE TABLE " + mTABLEMENUITEM +" ("+mITEMID+ " INTEGER PRIMARY KEY AUTOINCREMENT, " +mITEMNAME+" VARCHAR(255) NOT NULL, "+mITEMPRICE+" VARCHAR(255) NOT NULL, "+mITEMCATEGORY+" VARCHAR(255) NOT NULL);";
    public DataBaseHelper(Context context) {
        super(context, mDATABASENAME, null, mVERSION);
        this.context=context;
        Message.message(context,"on constructor called");

    }

    @Override
    public void onCreate(SQLiteDatabase db) {
        db.execSQL(mCREATETABLEUSER);

        db.execSQL(mCREATETABLEMENU);
        Message.message(context, "on create called");

    }

    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        db.execSQL("DROP TABLE IF EXISTS " + mTABLEUSERDETAIL);

         db.execSQL("DROP TABLE IF EXISTS " + mTABLEMENUITEM);
        Message.message(context, "on upgrade  called");
        onCreate(db);

    }

}

INSERT INTO menuitem(item category,itemprice,itemname) VALUES (?,?,?)

有你的错误,“项目类别”应该是“项目类别”,你在某处添加了一个空格,并且 sqlite 认为你试图插入四个值而不是三个值。

具体来说,这里:

private final static String mITEMCATEGORY="item category";
