Android中变量的命名规范

Follow Field Naming Conventions

• Non-public, non-static field names start with m.

• Static field names start with s.

• Other fields start with a lower case letter.

• Public static final fields (constants) are ALL_CAPS_WITH_UNDERSCORES.

  • 非公有、非静态域的变量以m开头（其实就是protected和private成员变量）
  • 静态变量以s开头
  • 其它变量以小写字母开头
  • Public static final变量（常量）以下划线连接全大写ALL_CAPS_WITH_UNDERSCORES
  
  

For example:

public class MyClass {
    public static final int SOME_CONSTANT = 42;
    public int publicField;
    private static MyClass sSingleton;
    int mPackagePrivate;
    private int mPrivate;
    protected int mProtected;
}
