Menampilkan Data Menggunakan RecyclerView (Retrofit) Part 1


Hello Sobat, Hari ini saya akan memberikan tutorial untuk menampilkan data menggunakan RecylerView dengan  HTTP REQUEST menggunakan library Retrofit untuk lebih jelasnya mengenai library ini sobat bisa kunjungi situs resminya disini, Tanpa berpikir panjang karna saya sudah kehabisan kata-kata saya akan memberikan langkah-langkah untuk membuat aplikasinya perhatikan iya.

Membuat Databases
Sobat copy code databases dibawah ke mysql



/* Navicat MySQL Data Transfer Source Server : tanwir Source Server Version : 50624 Source Host : localhost:3306 Source Database : db_blogspot Target Server Type : MYSQL Target Server Version : 50624 File Encoding : 65001 Date: 2017-07-03 09:16:54 */ SET FOREIGN_KEY_CHECKS=0; -- ---------------------------- -- Table structure for siswa -- ---------------------------- DROP TABLE IF EXISTS `siswa`; CREATE TABLE `siswa` ( `nis` int(11) NOT NULL, `nama` varchar(255) DEFAULT NULL, PRIMARY KEY (`nis`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1; -- ---------------------------- -- Records of siswa -- ---------------------------- INSERT INTO `siswa` VALUES ('1111', 'CodeTR'); INSERT INTO `siswa` VALUES ('2222', 'Randi'); INSERT INTO `siswa` VALUES ('3333', 'Tanwir'); INSERT INTO `siswa` VALUES ('5555', 'Hama'); INSERT INTO `siswa` VALUES ('6666', 'Cinta'); INSERT INTO `siswa` VALUES ('7777', 'Naruto'); INSERT INTO `siswa` VALUES ('8888', 'Budi'); INSERT INTO `siswa` VALUES ('9999', 'Tutu'); INSERT INTO `siswa` VALUES ('67676', 'hgfh');

 Membuat API menggunakan PHP
Sesuaikan dengan nama yang diberikan
  • koneksi.php
PHP

<?php
// deklarasi variable untuk koneksi ke MySQL
$hostname = "localhost";
$username = "root";
$password = "";
$database = "db_blogspot";

// membuat koneksi ke MySQL
$status = mysqli_connect($hostname, $username, $password, $database);
if (!$status){
die("Koneksi ke MySQL gagal dilakukan!<br>");
}
?>
  • siswa.php
PHP

<?php if($_SERVER['REQUEST_METHOD']=='GET'){ require_once('koneksi.php'); $sql = "SELECT * FROM siswa"; $result = mysqli_query($status,$sql); $total_results = mysqli_num_rows($result); $res = array(); if ($total_results == 0){ array_push($res, array("pesan"=>"Data tidak ada..!!!", $total_results)); }else{ while($row = mysqli_fetch_array($result)){ array_push($res, array("nis"=>$row['nis'],"nama"=>$row['nama'],"jmhdata"=>$total_results)); } } echo json_encode($res); mysqli_close($status); } ?>

 Android Studio
Selanjutnya masuk ke tools android studio buat project baru 
  • Membuat desian layout denga struktur sebagai berikut

  • Masukan source code xml dibagian content_main.xml


<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:id="@+id/content_main" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    app:layout_behavior="@string/appbar_scrolling_view_behavior" 
    tools:context="com.codetr.tanwir.codetr.MainActivity" 
    tools:showIn="@layout/activity_main"> 
 
    <android.support.v7.widget.RecyclerView 
        android:id="@+id/ryView" 
        android:layout_width="match_parent" 
        android:layout_height="match_parent" 
        android:scrollbars="none" /> 
 
</RelativeLayout>
  • Membuat item dengan nama item_siswa.xml dan masukan source code berikut

  • Jika sudah selesai melakukan design pada tampilan layout selanjutnya melakukan penambahan uses permission pada Manifest


<uses-permission android:name="android.permission.INTERNET" />
  • Menambahkan library di bagian gridle


compile 'com.android.support:recyclerview-v7:25.3.1'compile 'com.squareup.retrofit2:retrofit:2.1.0'compile 'com.squareup.retrofit2:converter-gson:2.1.0'

  • Perhatikan struktur folder code java
  • Tambahkan di folder adapter dengan nama SAdapter.java dan masukan source code
