Register dan Login Android Menggunakan Async Task

Ke Database Server

Oleh Yusuf Mufti – ym1315@gmail.com- yusufmufti.com

Membuat Register / Pendaftaran dan Login pada Android akan dibahas berikut ini,

Langkah-langkahnya

1. Membuat database

2. Membuat PHP untuk handle request

3. Membuat projek Android

A. Membuat Database.

Buatlah database dengan nama “login” dan buatlah tabel “user”. Adapun struktur tabel

user sebagai berikut ini.

B. PHP untuk handle request

Ada 3 file PHP yang kita akan buat, yaitu koneksi.php,register.php dan login.php dan

simpan di htdocs dengan folder “login”.

- File koneksi.php

mysql_connect("localhost","root","");

mysql_select_db("login");

- File register.php

$email = $_POST['email'];

$password=$_POST['password'];

$alamat=$_POST['alamat'];

$telepon=$_POST['telepon'];

$nama=$_POST['nama'];

include "koneksi.php";

$namaTabel = "user";

header('Content-Type: text/xml');

$query = "INSERT INTO $namaTabel

VALUES('','$nama','$email','$password','$alamat','$telepon')";

$hasil = mysql_query($query);

if($hasil)

$response["success"] = "1";

$response["message"] = "Data sukses diinput";

echo json_encode($response);

{$response["success"] = "0";

$response["message"] = "Maaf , terjadi kesalahan";

// echoing JSON response

- File login.php

include "koneksi.php";

$username = $_GET["username"];

$password = $_GET["password"];

$query = "select * from user where email='$username' and

password='$password' ";

$hasil = mysql_query($query);

if (mysql_num_rows($hasil) > 0) {

$response = array();

$response["login"] = array();

while ($data = mysql_fetch_array($hasil))

$h['id'] = $data['id'] ;

$h['nama'] = $data['nama'] ;

$h['alamat'] = $data['alamat'] ;

$h['email'] = $data['email'];

array_push($response["login"], $h);

else {

$response["message"] = "Tidak ada data";

C. Membuat Projek Android

- Membuat projek Android dengan klik File > New > Android Application Project,

kemudian konfigurasi untuk penamaan package, icon, dan file xml.

- Membuat file xml di folder res layout

Sebelum membahas kodenya, saya ingin menunjukkan struktur file di folder res sebagai

berikut

1. activity_dashboard.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

xmlns:tools="http://schemas.android.com/tools"

android:id="@+id/LinearLayout1"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:orientation="vertical"

android:paddingBottom="@dimen/activity_vertical_margin"

android:paddingLeft="@dimen/activity_horizontal_margin"

android:paddingRight="@dimen/activity_horizontal_margin"

android:paddingTop="@dimen/activity_vertical_margin"

tools:context=".Dashboard" >

<ScrollView

android:scrollbarStyle="insideInset">

<LinearLayout

android:orientation="vertical">

<LinearLayout

android:layout_height="wrap_content"

android:layout_marginTop="20sp">

<Button

android:id="@+id/pasang"

android:layout_width="0dp"

android:layout_weight="1"

style="@style/DashboardButton"

android:drawableTop="@drawable/tomboladd"

android:text="Akun"

android:textColor="#000000"/>

</LinearLayout>

<LinearLayout

android:layout_marginTop="20sp">

<Button

android:id="@+id/exit"

android:layout_width="0dp"

android:layout_weight="1"

style="@style/DashboardButton"

android:drawableTop="@drawable/tombolexit"

android:text="Keluar"

android:textColor="#000000"/>

</LinearLayout>

</ScrollView>

</LinearLayout>

Sedikit tambahan,

1. Untuk file dimens.xml di dalam folder res /value pastikan terdapat kode berikut

2. Kemudian untuk styles.xml di dalam folder res/value pastikan terdapat kode

berikut ini, jika tidak ada ketikalah di dalam <resource></resource>

<item name="android:layout_gravity">center_vertical</item>

<item name="android:layout_width">wrap_content</item>

<item name="android:layout_height">wrap_content</item>

<item name="android:gravity">center_horizontal</item>

<item name="android:textColor">#ffffff</item>

</style>

3. Kode tomboladd.xml di dalam folder res/drawable-hdpi

<item android:drawable="@drawable/add_100_pressed"

android:state_focused="true"

android:state_pressed="true" />

android:state_focused="false"

android:state_focused="true" />

<item android:drawable="@drawable/add_100"

android:state_pressed="false" />

</selector>

4. Kode tombolexit.xml di dalam folder res/drawable-hdpi

<item android:drawable="@drawable/exit_pressed"

android:state_focused="true"

android:state_focused="true" />

<item android:drawable="@drawable/exit"

android:state_pressed="false" />

</selector>

5. Androidmanifest.xml editlah menjadi seperti berikut ini

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.yusfa.login" android:versionCode="1" android:versionName="1.0" > <uses-sdk android:minSdkVersion="8" android:targetSdkVersion="17" />  <uses-permission android:name="android.permission.INTERNET"/> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <application android:allowBackup="true" android:icon="@drawable/icon" android:label="@string/app_name" android:theme="@style/AppTheme" > <activity android:name="com.login.Dashboard" android:label="@string/app_name" > <intent-filter> <action android:name="android.intent.action.MAIN" />
