使用此对话框执行 [Change Signature 重构](change-signature.html)。

使用可用的控件更改方法签名。 指定应如何处理方法调用。

点击   重构   立即执行重构。 点击   预览   可在实际重构之前查看 [查找工具窗口](find-tool-window.html) 中的潜在更改。

|  条目  |  描述  |
| --- | --- |
|  可见性  |  从列表中选择方法可见性范围（访问级别修饰符）。  |
|  返回值类型  |     使用此字段修改方法返回值类型。       [代码补全](auto-completing-code.html) `Ctrl+Space` (Windows), `⌃ Space` (macOS), `⌃ Space` (IntelliJ IDEA Classic (macOS)), `⌃ Space` (macOS System Shortcuts), `Ctrl+Space` (XWin), `Ctrl+Space` (GNOME), `Ctrl+Space` (KDE), `Alt+/` (Emacs), `Ctrl+Space` (Sublime Text), `⌃ Space` (Sublime Text (macOS)), `Ctrl+Space` (Visual Studio), `⌃ Space` (Visual Studio (macOS)), `Ctrl+Space` (NetBeans), `Ctrl+Space` (Eclipse), `⌃ Space` (Eclipse (macOS)) 在此字段中可用，并且在用于指定类型的其他字段中也可用。     |
|  名称  |  使用此字段修改方法名称。  |
|  修改方法调用  |  现有的方法调用已被修改，因此调用了具有新签名的方法。  |
|  添加到定义  |  如果选择此选项，将向方法定义中添加新参数。  |
|  指定结果类型  |  使用此选项配置类型注解设置。  |
|  签名预览  |  在此区域，当前方法签名会显示。 （此区域中的信息与您对方法签名所做的更改同步。）  |

在指定参数的区域，您可以添加新的参数、编辑、重新排序或删除现有参数。 重构将相应地分配您的更改。

若要开始编辑参数，请点击它。 或者，使用 `Up` (Windows), `↑` (macOS), `↑` (IntelliJ IDEA Classic (macOS)), `↑` (macOS System Shortcuts), `Up` (XWin), `Up` (GNOME), `Up` (KDE), `Up` (Emacs), `Up` (Sublime Text), `↑` (Sublime Text (macOS)), `Up` (Visual Studio), `↑` (Visual Studio (macOS)), `Up` (NetBeans), `Up` (Eclipse), `↑` (Eclipse (macOS)) 和 `Down` (Windows), `↓` (macOS), `↓` (IntelliJ IDEA Classic (macOS)), `↓` (macOS System Shortcuts), `Down` (XWin), `Down` (GNOME), `Down` (KDE), `Down` (Emacs), `Down` (Sublime Text), `↓` (Sublime Text (macOS)), `Down` (Visual Studio), `↓` (Visual Studio (macOS)), `Down` (NetBeans), `Down` (Eclipse), `↓` (Eclipse (macOS)) 箭头键导航到感兴趣的参数，并使用 `Enter` (Windows), `⏎` (macOS), `⏎` (IntelliJ IDEA Classic (macOS)), `⏎` (macOS System Shortcuts), `Enter` (XWin), `Enter` (GNOME), `Enter` (KDE), `Enter` (Emacs), `Enter` (Sublime Text), `⏎` (Sublime Text (macOS)), `Enter` (Visual Studio), `⏎` (Visual Studio (macOS)), `Enter` (NetBeans), `Enter` (Eclipse), `⏎` (Eclipse (macOS)) 开始修改它。
