Cara Buat Tampilan LOGIN Keren Dengan Android Studio


Cara  Buat Tampilan LOGIN Keren 

Dengan Android Studio

Jika sebelumnya kita pernah belajar membuat ui login desain menarik dalam 30 menit menggunakan android studio. Kali ini kita akan belajar membuat form  login android pada android studio dengan menggunakan sqlite database.
Untuk  aplikasi login sqlite yang sudah running kamu bisa melihatnya pada video dibawah ini.

Membuat Login Android 

Tanpa basa basi langsung saja kita praktekan membuat login android menggunakan sqlite database.

1. Buat Project Baru

Langkah pertama silahkan buat project baru di android studio dengan menggunakan nama project loginsqlite. Jika masih bingung kamu bisa membaca tutorial membuat project pertama di android.

2. Library Material Design

Tambahkan library material design dengan cara klik gradle (module:app) > masukan 1 baris kode berikut pada dependencies > klik sync now (pastikan terknoneksi dengan internet ) 
implementation 'com.android.support:design:26.1.0'

3. Edit String

Edit string yang nantinya digunakan untuk nama aplikasi dan beberapa komponen widget. Buka res > values > string.xml. disini Kamu bisa pelajari struktur folder android .
<resources>
    <string name="app_name">LoginRegisterScreenDesign</string>
    <string name="create_account"><font color="#00ff00">text</font></string>
    <string name="email">Email</string>
    <string name="password">Password</string>
    <string name="login">Login</string>
    <string name="username">Username</string>
    <string name="register">Register</string>
    <string name="back_to_login">Back to Login</string>
</resources>

4. Edit Color

Edit warna yang dengan cara buka res > values > colors.xml. 
<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="colorPrimary">#607d8b</color>
    <color name="colorPrimaryDark">#455a64</color>
    <color name="colorAccent">#0c0099</color>
</resources>

5. Drawable

Copykan gambar/ icon pendukung  (download disini ). Caranya klik kanan pada drawable > klik paste. 

6. Edit Style

Edit tema pada res > values > styles.xml. Dalam aplikasi yang akan kita buat ini kita tidak akan menampilkan action bar (app bar). Sehingga kode-kodenya kita edit menjadi seperti seperti berikut.
<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>

    <style name="AppTheme.NoActionBar">
        <item name="windowActionBar">false</item>
        <item name="windowNoTitle">true</item>
    </style>

    <style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />

    <style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light" />

</resources>

7. Activity Login

Buat activity login dengan cara klik folder java > klik kanan nama package > New > Activity > Empty Activity > Isikan Nama LoginActivity. Sehingga akan terdapat class java LoginActivity.java dan layout activity_login.xml.
  • LoginActivity.java
Masukan kode-kode berikut dibawah nama package.

9. Class SqliteHelper

Tambahkan class SqliteHelper. Untuk membuatnya silahkan klik folder java > klik kanan pada nama package > pilih new > class > beri nama class SqliteHelper. Masukan kode-kode berikut ini pada SqliteHelper.java (tempatkan dibawah nama package).
import android.content.ContentValues;
import android.content.Context;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;



public class SqliteHelper extends SQLiteOpenHelper {

    //DATABASE NAME
    public static final String DATABASE_NAME = "loopwiki.com";

    //DATABASE VERSION
    public static final int DATABASE_VERSION = 1;

    //TABLE NAME
    public static final String TABLE_USERS = "users";

    //TABLE USERS COLUMNS
    //ID COLUMN @primaryKey
    public static final String KEY_ID = "id";

    //COLUMN user name
    public static final String KEY_USER_NAME = "username";

    //COLUMN email
    public static final String KEY_EMAIL = "email";

    //COLUMN password
    public static final String KEY_PASSWORD = "password";

    //SQL for creating users table
    public static final String SQL_TABLE_USERS = " CREATE TABLE " + TABLE_USERS
            + " ( "
            + KEY_ID + " INTEGER PRIMARY KEY, "
            + KEY_USER_NAME + " TEXT, "
            + KEY_EMAIL + " TEXT, "
            + KEY_PASSWORD + " TEXT"
            + " ) ";


    public SqliteHelper(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
    }

    @Override
    public void onCreate(SQLiteDatabase sqLiteDatabase) {
        //Create Table when oncreate gets called
        sqLiteDatabase.execSQL(SQL_TABLE_USERS);

    }

    @Override
    public void onUpgrade(SQLiteDatabase sqLiteDatabase, int i, int i1) {
        //drop table to create new one if database version updated
        sqLiteDatabase.execSQL(" DROP TABLE IF EXISTS " + TABLE_USERS);
    }

    //using this method we can add users to user table
    public void addUser(User user) {

        //get writable database
        SQLiteDatabase db = this.getWritableDatabase();

        //create content values to insert
        ContentValues values = new ContentValues();

        //Put username in  @values
        values.put(KEY_USER_NAME, user.userName);

        //Put email in  @values
        values.put(KEY_EMAIL, user.email);

        //Put password in  @values
        values.put(KEY_PASSWORD, user.password);

        // insert row
        long todo_id = db.insert(TABLE_USERS, null, values);
    }

    public User Authenticate(User user) {
        SQLiteDatabase db = this.getReadableDatabase();
        Cursor cursor = db.query(TABLE_USERS,// Selecting Table
                new String[]{KEY_ID, KEY_USER_NAME, KEY_EMAIL, KEY_PASSWORD},//Selecting columns want to query
                KEY_EMAIL + "=?",
                new String[]{user.email},//Where clause
                null, null, null);

        if (cursor != null && cursor.moveToFirst()&& cursor.getCount()>0) {
            //if cursor has value then in user database there is user associated with this given email
            User user1 = new User(cursor.getString(0), cursor.getString(1), cursor.getString(2), cursor.getString(3));

            //Match both passwords check they are same or not
            if (user.password.equalsIgnoreCase(user1.password)) {
                return user1;
            }
        }

        //if user password does not matches or there is no record with that email then return @false
        return null;
    }

    public boolean isEmailExists(String email) {
        SQLiteDatabase db = this.getReadableDatabase();
        Cursor cursor = db.query(TABLE_USERS,// Selecting Table
                new String[]{KEY_ID, KEY_USER_NAME, KEY_EMAIL, KEY_PASSWORD},//Selecting columns want to query
                KEY_EMAIL + "=?",
                new String[]{email},//Where clause
                null, null, null);

        if (cursor != null && cursor.moveToFirst()&& cursor.getCount()>0) {
            //if cursor has value then in user database there is user associated with this given email so return true
            return true;
        }

        //if email does not exist return false
        return false;
    }
}
Di dalam Class SqliteHelper merupakan bagian dari SQLiteOpenHelper di dalamnya terdapat :
  • Nama database
  • Versi database
  • Tabel
  • Kolom

10. Class User

Tambahkan class User yang akan dijadikan model dari user.  Untuk membuatnya sama seperti point 8, lalu beri nama class User. Tambahkan kode-kode dibawah ini pada User.java.
public class User {
    public String id;
    public String userName;
    public String email;
    public String password;

    public User(String id, String userName, String email, String password) {
        this.id = id;
        this.userName = userName;
        this.email = email;
        this.password = password;
    }

}

 11. Home Screen

Jika login berhasil maka aplikasi akan menampilkan home screen. Home screen yang kita buat kali ini hanya menampilkan komponen TextView.Tambahkan kode-kode dibawah ini pada activity_main.xml. 
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout 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:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="badoystudio.com.loginsqlite.MainActivity">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="20sp"
        android:text="Kamu telah berhasil login "
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

</android.support.constraint.ConstraintLayout>

12. Android Manifest

Buka AndroidManifest.xml yang ada pada folder app > manifest. Edit kode-kodenya sehingga menjadi seperti dibawah ini(pakcagenya sesuaikan dengan nama package yang kamu buat).
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="badoystudio.com.loginsqlite">

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity
            android:name=".LoginActivity"
            android:label="@string/app_name"
            android:theme="@style/AppTheme.NoActionBar">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity
            android:name=".RegisterActivity"
            android:label="@string/app_name"
            android:theme="@style/AppTheme.NoActionBar" />

        <activity
            android:name=".MainActivity"
            android:label="Home Screen"
            android:theme="@style/AppTheme.NoActionBar" />


    </application>

</manifest>

13. Running Project
