Android:Eclipse如何设置格式化Java代码

为了避免截图，从另外一篇文章中抄来了图片：http://www.avajava.com/tutorials/lessons/how-do-i-create-a-profile-to-format-java-code-in-eclipse.html?page=2

1. 首先创建一个新的格式化Profile

菜单 Window → Preferences 选择Java → Code Style → Formatter. 点击New按钮进行新建Profile

2.基于内置的Eclipse格式新建一个Profile:myprofile

3.然后点击编辑进行设置：

本人是从C转过来的，对于Eclipse默认的Java的花括号格式非常的不习惯，还是喜欢c风格的花括号，其它的倒是无所谓。

因此主要修改了花括号的风格：

即在Braces页面，将大部分的设置从Same line改成Next line,这样看起来很舒服，很清楚每个block的起始位置。

下面是我的配置文件，可以通过Import按钮导入到你的环境中：
