Android Edit/Update Data to Web Server Database (Web Server) |
Android Edit/Update Data to Web Server Database (Web Server) ตัวอย่างการเขียน Android เพื่อทำการอัพเดดแก้ไขข้อมูล (Update) ที่อยู่ในฝั่งของ Web Server โดยใน Web Server จะใช้ PHP กับ MySQL ทำหน้าที่เป็นสื่อกลางที่จะจัดการข้อมูลที่ถูกส่งมาจาก Android Client ขั้นตอนการทำงานคือ Android จะอ่านข้อมูลจาก Web Server ทั้งหมดแสดงบน ListView จากนั้นจะให้เลือกแก้ไขข้อมูลในแต่ล่ะรายการ พร้อม ๆ กับการออกแบบ Form เพื่อรอรับการแก้ไขข้อมูลจากผู้ใช้
รูปภาพ Model การแก้ไขข้อมูลจาก Android เพื่อ Update ไปยัง Web Server
Basic Android Server and Client
AndroidManifest.xml
<uses-permission android:name="android.permission.INTERNET" />
ในการเขียน Android เพื่อติดต่อกับ Internet จะต้องกำหนด Permission ในส่วนนี้ด้วยทุกครั้ง
