在 IntelliJ 中重新排序 Java 类方法的简单方法？

Simple way to reorder methods of a Java class in IntelliJ?

提问by Péter T?r?k

Is there a simpler way of reordering methods within a class source file in IntelliJ than cutting and pasting the code manually? Nowadays I often need this while refactoring legacy code, e.g. to move related methods close to each other in the source code.

有没有比手动剪切和粘贴代码更简单的在 IntelliJ 中的类源文件中重新排序方法的方法？现在我在重构遗留代码时经常需要这个，例如在源代码中将相关方法彼此靠近。

In Eclipse AFAIK there is a view similar to the Structure view of IntelliJ, where I can drag and drop methods around. However, this does not work in IntelliJ and I couldn't find any hints from its help either.

在 Eclipse AFAIK 中有一个类似于 IntelliJ 的结构视图的视图，我可以在其中拖放方法。但是，这在 IntelliJ 中不起作用，我也无法从它的帮助中找到任何提示。

I am using IntelliJ 9.0.2 to be specific.

具体来说，我使用的是 IntelliJ 9.0.2。

You can select a method name and hit: Ctrl+Shift+Upor Ctrl+Shift+Downto move it up and down.

您可以选择的方法名称和命中：Ctrl+ Shift+Up或Ctrl+ Shift+Down将其上下移动。

On OS X: Cmd+Shift+Upor Cmd+Shift+Down

在OS X：Cmd+ Shift+Up或Cmd+ Shift+Down

Beyond this the Rearranger Pluginlets you move methods around quickly, and even define a standard ordering based on your coding convention.

除此之外，Rearranger Plugin允许您快速移动方法，甚至根据您的编码约定定义标准排序。

Select a block of text (hit Ctrl-W a few times) and then use Ctrl-Shift-Up and Ctrl-Shift-Down to move it around.

选择一个文本块（按几次 Ctrl-W），然后使用 Ctrl-Shift-Up 和 Ctrl-Shift-Down 来移动它。

With your cursor on the method definition line (you do not have to and press ctrl+shift+upor ctrl+shift+down, to move up or down respectively.

将光标放在方法定义行上（您不必按ctrl+ shift+up或ctrl+ shift+down分别向上或向下移动。

You can also to ctrl+shift+numberpad -to quickly collapse everything so you can focus on moving around (plain -works on my laptop as well, not sure why) and ctrl+shift+numberpad +to get back to see everything (ctrl-shift-equals works on my laptop as well).

您也可以以ctrl+ shift+numberpad -快速崩溃一切，让您可以专注于中移动（纯-的作品在我的笔记本电脑为好，不知道为什么）和ctrl+ shift+numberpad +要回看到的一切（按Ctrl移等于我的笔记本电脑作为作品好）。

Not a perfect answer yet, due to a bug in IntelliJ.

没有一个完美的答案还没有，因为在的IntelliJ的错误。

Though IntelliJ offers this feature implicitly, but it needs to be enabled as well as fixed. The OP's suggested way is technically arranging methods in depth-first order. However, if you use Breadth-first ordering(which works properly), it should reduce the manual work of moving functions by a lot, by arranging all caller and callee methods together.

尽管 IntelliJ 隐式提供了此功能，但它需要启用和修复。OP 建议的方法是在技术上按深度优先顺序排列方法。但是，如果您使用广度优先排序（它可以正常工作），通过将所有调用方和被调用方方法安排在一起，它应该可以减少大量移动函数的手动工作。

The appropriate action for this is Rearrange Code. This has no key assigned to it, but you can define your own using Preferences->Keymap.

对此的适当操作是重新排列代码。这没有分配给它的键，但您可以使用 Preferences->Keymap 定义自己的键。

IntelliJ has a built in system that allows you to specify how to order your methods. You need to go to Settings (Ctrl + Alt +S) -> Editor -> Code Style -> Java -> Arrangement (tab) and scroll down until you find the icons with methods. There you can manipulate the options to sort them by visibility, or alphabetically, or to keep related ones grouped together. Here is a screenshot of my settings which will order methods automatically by visibility (public, protected, private) and alphabetically (a-z). The blue highlights show the currently selected rules.

IntelliJ 有一个内置系统，允许您指定如何对方法进行排序。您需要转到设置 (Ctrl + Alt +S) -> 编辑器 -> 代码样式 -> Java -> 排列（选项卡）并向下滚动，直到找到带有methods. 您可以在那里操作选项以按可见性或字母顺序对它们进行排序，或将相关的组合在一起。这是我的设置的屏幕截图，它将按可见性（公共、受保护、私有）和字母顺序 (az) 自动对方法进行排序。蓝色高亮显示当前选择的规则。

There is an automated way, which you can later tweak

有一种自动化的方式，您可以稍后对其进行调整

Code -> show reformat file dialog

代码 -> 显示重新格式化文件对话框

and tick "rearrange code" box

并勾选“重新排列代码”框
