Android Update Data to Server via Web Service |
Android Update Data to Server via Web Service การเขียน Android เพื่อแก้ไข Update ข้อมูลที่อยู่บน Server Database ผ่าน Web Service ที่ทำงานร่วมกับ PHP กับ MySQL หลักการก็คือ ออกแบบ Web Service ไว้ 3 ตัวคือ
- getMember.php ว้สำหรับแสดงรายการข้อมูลทั้งหมดลงใน ListView ของ Android
- resultByMemberID.php ใช้สำหรับแสดงข้อมูลที่ได้เลือกทำการ Update
- updateMemberData.php ใช้สำหรับ Update ข้อมูลที่ถูกแก้ไขและส่งมาจาก Android
AndroidManifest.xml
<uses-permission android:name="android.permission.INTERNET" />
ในการเขียน Android เพื่อติดต่อกับ Internet จะต้องกำหนด Permission ในส่วนนี้ด้วยทุกครั้ง
