Android code specification 03, android code 03

I. sundy suggested the following directories for the entire project: system directory specification and source code directory specification.

1. System Directory specifications:

The project directory contains not only the source code, but also the requirement-related documents, design documents, plan log documents, test documents, and project learning documents (refer to the Demo ); make the entire project clearer,

2. Source Code directory specification:

Generally, the system namespace Directory should not exceed three layers. [organization name]. [project name]. [Module name]: mobidever. camera. pubshpic

Ii. common naming rules

1. Pascal naming method: String MyName; int MyAge // class name in JAVA

2. Camel naming method: String myName; int myAge // common in Java, Method Name

3. Hungarian name method: String strMyName; (VB6) String sMyName; int intMyName; // table name type prefix, attribute name

4. Underline naming: String s_MyName; private String m_MyName;

 

Private property: private int mAge;

Static variable: static String sName;

Internal variable of the function: int _ Age;

Parameter for method definition: int pAge;

It is better to form a good style and clearly distinguish the variables.

3. Notes

File, class, method, method parameter, variable, and attribute.

1. File and class annotations are in the JavaDoc format.

/**

*/

2. Variable comment: // my name

Private String mName;

Iv. import

Put them together, that is, all the namespaces defined by the framework are a group, and the custom and third-party namespaces are placed in another group.
