问题描述

限时送ChatGPT账号..

SQLiteDatabase db = this.getWritableDatabase();
ContentValues cv = new ContentValues();
  cv.put(colDeptID, 1);
  cv.put(colDeptName, "Sales");
  db.insert(deptTable, colDeptID, cv);

  cv.put(colDeptID, 2);
  cv.put(colDeptName, "IT");
  db.insert(deptTable, colDeptID, cv);
                    db.close();

使用此代码，在输入每一行并收到此错误后，我在括号下得到一个红色下划线:标记("上的语法错误，请删除此标记.

With this code, I am getting a red underline under the parenthesis after put in every line and getting this error: Syntax error on token "(", delete this token.

我也收到一条错误消息:令牌上的语法错误，而是预期的 variableDeclarator.有任何想法吗?我已经尝试了所有我知道的方法，但都没有奏效.

I also get an error that says: Syntax error on tokens, variableDeclarator expected instead. Any ideas? I've tried everything I know to do, and none of it worked.

我也得到关闭"时出现语法错误，此令牌后应有标识符

I also get Syntax error on "close", identifier expected after this token

我从教程中复制并粘贴了这段代码，所有评论都说它有效，但我遇到了很多问题.感谢您如此快速的回复.

I copy and pasted this code from a tutorial and all the comments said it worked, but I've had quite a few problems out of it. Thanks for such quick replies.

推荐答案

仅声明，例如:

SQLiteDatabase db = this.getWritableDatabase();
ContentValues cv = new ContentValues();

可以直接在类声明中.非声明，例如:

can be directly inside a class declaration. Non-declarations, such as:

  cv.put(colDeptID, 1);
  cv.put(colDeptName, "Sales");
  db.insert(deptTable, colDeptID, cv);

必须在方法、构造函数、初始化块或静态初始化块中.在这种情况下，它们可能应该在构造函数或方法中.

must be inside a method, constructor, initializer block, or static initializer block. In this case they should probably be in a constructor or method.
