【详细】idea设置格式化方式 google style

下载google style文件

Google 在 GitHub 上有一个专门放置编码规范的仓库，地址在：
https://github.com/google/styleguide
里面有一个intellij-java-google-style.xml文件，链接：google-style.xml文件链接

修改google style文件

这个文件直接导入idea会出现一些问题（例如tab键默认2格，回车也是2格，导致更加不规范），所以需要修改一下
主要修改这三个配置

<option name="INDENT_SIZE" value="4" />
<option name="TAB_SIZE" value="4" />
<option name="CONTINUATION_INDENT_SIZE" value="8" />

• INDENT_SIZE：缩进宽度（一般指普通语句块的缩进）
• TAB_SIZE：一个 制表符 Tab 显示为多少个空格（TAB_SIZE=4 → 1 个 Tab 看起来等于 4 个空格；TAB_SIZE=2 → 1 个 Tab 看起来等于 2 个空格）
• CONTINUATION_INDENT_SIZE：换行缩进量，也就是代码太长换行时的额外缩进

这里可以全局搜索替换，也可以直接用我给的模版：

使用google style文件

step1：导入xml文件

设置一个名字，应用即可。

应用——确定
然后随便修改一个文件（加空格等），保存，可以看到全部格式化完成。
