Aplikasi Android Studio Menggunakan Listview

Aplikasi Sederhana Android Studio Menggunakan Listview

Aplikasi Sederhana Android Studio Menggunakan Listview, dimana Listview tersebut digunakan untuk memanggil Activity lain. Listview akan berisikan nama-nama group band yang jika di klik salah satu akan memanggil activity lain yng berisikan info band tersebut.

Aplikasi terdiri dari 3 Activity yaitu :

1. Login

2. Listview (daftar nama band)

3. Activity (info band)

Pembuatan Aplikasi :

1. Membuat Form Login

XML Login

</androidx.constraintlayout.widget.ConstraintLayout>

Activity Login

package com.e.utsmobileprograming;

import androidx.appcompat.app.AppCompatActivity;

import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;

public class Login extends AppCompatActivity {

    EditText ussername,password;
    Button btnLogin;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_login);

        ussername=(EditText) findViewById(R.id.id_ussername);
        password=(EditText) findViewById(R.id.id_password);
        btnLogin=(Button)findViewById(R.id.btn_login);
        btnLogin.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View view) {
                if (ussername.getText().toString().equals("Fikryfitriansyah") && password.getText().toString().equals("fikryfitriansyah97")){
                    Toast.makeText(getApplicationContext(),"Anda Login Sebagai : " + ussername.getText().toString() + "dan Password : " + password.getText().toString(),Toast.LENGTH_SHORT).show();
                    Intent i = new Intent(Login.this, Listview.class);
                    i.putExtra("Username",ussername.getText().toString());
                    i.putExtra("Password",password.getText().toString());
                    startActivity(i);
                }
                else {
                    Toast.makeText(getApplicationContext(),"Gagal Login",Toast.LENGTH_SHORT).show();
                }
            }
        });
    }
}

2. Membuat Listview (Daftar Nama Band)

XML Listview

<?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:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".Listview">

    <ListView
        android:id="@+id/listview"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
</RelativeLayout>

Activity Listview

import android.content.Intent;
import android.os.Bundle;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.view.View;
import android.widget.Toast;


public class Listview extends AppCompatActivity {

    ListView list;
    String rock[] = {"Profil", "Beatles", "Led Zeppelin", "Rolling Stones", "Queen",
            "Deep Purple", "Black Sabbath", "Pink Floyd"};

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_listview);
        list = (ListView) findViewById(R.id.listview);
        ArrayAdapter adapter = new ArrayAdapter(this, android.R.layout.simple_expandable_list_item_1, rock);
        list.setAdapter(adapter);


        list.setOnItemClickListener(new AdapterView.OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
                int item = arg2;
                String itemText = (String) list.getItemAtPosition(arg2);

                if (itemText.equals("Profil")) {
                    Intent profil = new Intent(arg0.getContext(), Profil.class);
                    startActivityForResult(profil, 0);
                    Toast.makeText(getApplicationContext(),"Anda Membuka Profil",Toast.LENGTH_SHORT).show();

                } else if (itemText.equals("Beatles")) {
                    Intent beatles = new Intent(arg0.getContext(), Beatles.class);
                    startActivityForResult(beatles, 0);
                    Toast.makeText(getApplicationContext(),"Anda Membuka The Beatles",Toast.LENGTH_SHORT).show();

                } else if (itemText.equals("Led Zeppelin")) {
                    Intent ledzeppelin = new Intent(arg0.getContext(), LedZeppelin.class);
                    startActivityForResult(ledzeppelin, 0);
                    Toast.makeText(getApplicationContext(),"Anda Membuka Led Zeppelin",Toast.LENGTH_SHORT).show();

                } else if (itemText.equals("Rolling Stones")) {
                    Intent rollingstones= new Intent(arg0.getContext(), RollingStones.class);
                    startActivityForResult(rollingstones, 0);
                    Toast.makeText(getApplicationContext(),"Anda Membuka The Rolling Stones",Toast.LENGTH_SHORT).show();

                } else if (itemText.equals("Queen")) {
                    Intent queen = new Intent(arg0.getContext(), Queen.class);
                    startActivityForResult(queen, 0);
                    Toast.makeText(getApplicationContext(), "Anda Membuka Queen", Toast.LENGTH_SHORT).show();

                } else if (itemText.equals("Deep Purple")) {
                    Intent deepppurple = new Intent(arg0.getContext(), DeepPurple.class);
                    startActivityForResult(deepppurple, 0);
                    Toast.makeText(getApplicationContext(), "Anda Membuka Deep Purple", Toast.LENGTH_SHORT).show();

                } else if (itemText.equals("Black Sabbath")) {
                    Intent blacksabbath = new Intent(arg0.getContext(), BlackSabbath.class);
                    startActivityForResult(blacksabbath, 0);
                    Toast.makeText(getApplicationContext(), "Anda Membuka Black Sabbath", Toast.LENGTH_SHORT).show();

                } else if (itemText.equals("Pink Floyd")) {
                    Intent pinkfloyd = new Intent(arg0.getContext(), PinkFloyd.class);
                    startActivityForResult(pinkfloyd, 0);
                    Toast.makeText(getApplicationContext(), "Anda Membuka Pink Floyd", Toast.LENGTH_SHORT).show();
                }






            }
        });
    }
}

3. Membuat Activity (Info Band)

XML Activity (Info Band)

<?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:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#3F51B5"
    tools:context=".Beatles">

    <TextView
        android:id="@+id/textView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="10dp"
        android:textStyle="bold"
        android:textSize="35sp"
        android:textColor="#F7F2F2"
        android:text="The Beatles" />

    <ImageView
        android:id="@+id/imageView"
        android:layout_width="150dp"
        android:layout_height="200dp"
        android:layout_marginTop="65dp"
        android:layout_centerHorizontal="true"
        app:srcCompat="@drawable/beatles" />

    <TextView
        android:id="@+id/textView3"
        android:layout_width="350dp"
        android:layout_height="wrap_content"
        android:layout_marginTop="260dp"
        android:textSize="18sp"
        android:textColor="#F7F2F2"
        android:layout_centerHorizontal="true"
        android:text="
        \n      The Beatles adalah kelompok pemusik Inggris beraliran rock, dibentuk di Liverpool pada tahun 1960, seringkali dianggap sebagai pemusik tersukses secara komersial dan paling banyak mendapat pujian dalam musik populer. Sejak tahun 1962,
        \n      kelompok ini terdiri dari John Lennon (gitar ritem, vokal), Paul McCartney (gitar bass, vokal), George Harrison (gitar utama, vokal), Ringo Starr (drum, vokal)." />

</RelativeLayout>

Activity Info Band

package com.e.utsmobileprograming;

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;

public class Beatles extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_beatles);
    }
}

Jadi pertama kita harus Login terlebih dengan memasukkan Ussername dan Password, jika berhasil Login maka akan membuka Form Listview. Lalu pilih salah satu nama band yang ada pada daftar Listview untuk membuka Activity info band tersebut.

Sekian Pembuat Aplikasi Sederhana Android Studio Menggunakan Listview.

Perancangan Basis Data Sql Server 2012 dan Website pada Asp.Net dengan Metode Normalisasi

Pada postingan kali ini saya menulis tentang perancangan basis data (database) dari sebuah struk belanja. Perancangannya melewati beberapa tahap diantaranya Unnormalized, 1NF, 2NF, 3NF & Relasi. setelah membuat perancangan lanjut ke tahap penerapannya yaitu dengan membuat tabel - tabel pada software Sql Server 2012. setelah tabel-tabel tersebut selesai selanjutnya buat project web dengan visual studio (ASP.NET) lalu mengkoneksikan database tersebut, pada database juga saya berikan perintah - perintah yaitu simpan, edit, hapus dan cari. Untuk lebih jelasnya saya akan menjelaskan sebagai berikut :

Ini Struk Belanja yang saya gunakan sebagai bahan

1. Membuat Basis data menggunakan Metode Normalisasi

A. Bentuk Unnormalized

Bentuk ini merupakan kondisi data apa adanya, tidak mengikuti suatu format tertentu termasuk ketidak lengkapan ataupun redundansi

B. Bentuk Normal 1 (1NF)
Bentuk normal pertama jika relasi tidak mengandung atribut yang bernilai ganda harus mengandung 1 nilai) dan harus diisi datanya (tidak boleh kosong)

C. Bentuk Normal 2 (2NF)
Telah memenuhi 1NF

D. Bentuk Normal 3 (3NF)
Telah memenuhi 2NF. Semua atribut bukan primer tidak punya hubungan yang transitif (tidak ada dependensi transitif).

E. Tabel Relasi
Semua tabel yang ada di 3NF dihubungkan.

2. Setelah melewati tahap normalisasi kita lanjut membuat Basis Data (DATABASE) pada Sql Server 2012 sesuai dengan bentuk normal 3 (3NF).

3. Setelah database selesai dibuat. langkah selanjutnya membuat website pada visual studio (ASP.Net)

Tampilan Awal, yang nantinya apabila di klik akan memunculkan Tabel-tabel.

Koneksi Visual Studio Ke Database Ms.Access

Membuat Koneksi Visual Studio Ke Ms.Access

Disini saya akan membuat Aplikasi sederhaha menggunakan Visual Studio Ultimate 2012, disini Aplikasi berbasis Web (Web Form asp.net) yang nantinya Data yang di buat pada Aplikasi tersebut akan tersimpan di Ms.Access

Ini Desain sederhana Aplikasi yang saya buat

Buat juga Tabel di Ms.Acccess sesuai dengan Aplikasi yang kita buat pada Visual Sutio

Jalankan Aplikasi dan masukan Datanya, lalu tekan tombol simpan, Jika sukses tekan tombol lihat

Data akan masuk ke Database Ms.Acces

Untuk dapat melihat Database, buat Web Form baru lalu Drag and Drop database yang sudah di buat ke Web Form baru tersebut

Ini Untuk semua Codingnya

Koneksi untuk Database Access

Imports System.Data
Imports System.Data.OleDb
Public Class UAS
Inherits System.Web.UI.Page
Dim Koneksi As String = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=E:\New folder (2)\Database\UAS.accdb"
Dim ObjKoneksi As New OleDb.OleDbConnection(Koneksi)
Dim xReader As OleDb.OleDbDataReader

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

End Sub
