Android PHP/MySQL (UTF-8) : รับ-ส่ง ภาษาไทย ระหว่าง Android กับ MySQL |
Android PHP/MySQL (UTF-8) : รับ-ส่ง ภาษาไทย ระหว่าง Android กับ MySQL ตัวอย่างการเขียน Android ติดต่อกับ PHP และ MySQL Database ผ่าน HttpPost ที่อยู่ในรูปแบบของ URL Website จากแหล่งต่าง ๆ โดย Android จะใช้ HttpPost และ HttpGet ในรูปแบบของข้อความภาษาไทย (Thai Wording) โดยจะใช้รูปแบบการรับ-ส่งข้อมูลแบบ (UTF-8 Encoding)
ในการส่ง Post ที่เป็นภาษาไทยให้เพื่มคำสั่ง httpPost.setEntity(new UrlEncodedFormEntity(params,"UTF-8")); เข้าไปใน HttpPost
และที่ PHP กับ MySQL จะต้องใช้ mysql_query("SET NAMES UTF8");
Basic Android and JSON
AndroidManifest.xml
<uses-permission android:name="android.permission.INTERNET" />
ในการเขียน Android เพื่อติดต่อกับ Internet จะต้องกำหนด Permission ในส่วนนี้ด้วยทุกครั้ง
Example การรับส่งภาษาไทยระหว่าง Android กับ PHP/MySQL
Web Server (PHP and MySQL)
member
CREATE TABLE `member` (
`MemberID` int(2) NOT NULL auto_increment,
`Username` varchar(50) NOT NULL,
`Password` varchar(50) NOT NULL,
`Name` varchar(50) NOT NULL,
`Tel` varchar(50) NOT NULL,
`Email` varchar(150) NOT NULL,
PRIMARY KEY (`MemberID`),
UNIQUE KEY `Username` (`Username`),
UNIQUE KEY `Email` (`Email`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=4 ;
--
-- Dumping data for table `member`

INSERT INTO `member` VALUES (1, 'weerachai', 'weerachai@1', 'Weerachai Nukitram', '0819876107', '[email protected]');
