android - Multiple markers at this line - Syntax error on token ",", ; expected

Question

@Override
public void onActivityResult((int requestCode,int resultCode,Intent data))
{
    super.onActivityResult(requestCode, resultCode, data);
    fb.authorizeCallback(requestCode, resultCode, data);
}

I actually took the above code from net and placed but am getting error like this:

Multiple markers at this line:

• Syntax error on token ",", ; expected
• Syntax error on token ",", ; expected
• Syntax error on token(s), misplaced construct(s)
• void is an invalid type for the variable onActivityResult
• Syntax error, insert ";" to complete LocalVariableDeclarationStatement
• Syntax error, insert ";" to complete LocalVariableDeclarationStatement

Answer 1

去掉多余的括号：

public void onActivityResult((int requestCode,int resultCode,Intent data))

试试这个：

public void onActivityResult(int requestCode, int resultCode, Intent data)

Answer 2

您的方法签名中有一组额外的括号。尝试使用：

@Override
protected void onActivityResult(int requestCode,int resultCode,Intent data)
{
    super.onActivityResult(requestCode, resultCode, data);
    fb.authorizeCallback(requestCode, resultCode, data);
}

Answer 3

这一行：

public void onActivityResult((int requestCode,int resultCode,Intent data))

应该：

public void onActivityResult(int requestCode,int resultCode,Intent data)

请注意删除了方法参数周围的第二组括号。

Answer 4

参数说明的括号是多余的。尝试：

@Override
public void onActivityResult(int requestCode,int resultCode,Intent data)
{
    super.onActivityResult(requestCode, resultCode, data);
    fb.authorizeCallback(requestCode, resultCode, data);
}

如果仍然遇到语法错误，粘贴整个 Activity 类的源代码会很有帮助。
