Project Mobile Programming | UTS_06TPLP003

Assalamu’alaikum Wr.Wb

Di tutorial saya kali ini, saya akan mencoba membuat project tentang mobile programming dengan software android studio "cara membuat aplikasi Digital Shop berbasis android”. Didalam aplikasi digital shop saya terdapat form login, tampilan welcome, menu tabhost, dan exit.

Tanpa basa basi langsung saja kita lakukan langkah - langkah pembuatannya >>>

Didalam project saya terdapat 7 Activity.java yaitu :

1. MainActivity.java

2. Welcome.java

3. TabHostActivity.java

4. Menu.java

5. Pesan.java

6. CostumListAdapter.java

7. Exit.java

Dan terdapat 7 Activity.xml yaitu :

1. activity_main.xml

2. activity_welcome.xml

3. activity_tab_host.xml

4. activity_menu.xml

5. activity_pesan.xml

6. activity_list.xml

7. activity_exit.xml

Langkah pertama mari kita buat dulu designnya, berikut dibawah ini code XML untuk designnya

package com.example.project_uts;

import android.content.Intent;

import android.support.v7.app.AppCompatActivity;

import android.os.Bundle;

import android.view.View;

import android.widget.Button;

public class Exit extends AppCompatActivity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_exit);

getSupportActionBar().setTitle("DIGITAL_SHOPE");

Button btnbck = (Button) findViewById(R.id.btnbck);

btnbck.setOnClickListener(new View.OnClickListener(){

@Override

public void onClick(View v){

Intent intent = new Intent(Exit.this,MainActivity.class);

Exit.this.startActivity(intent);

finish();

}

});

}

Setelah codingannya selesai semua, mari kita RUN dan lihat hasil designnya dan lakukan proses - prosesnya.

note: Saya menjalankan aplikasi ini menggunakan gadget android langsung.

1. Form login (Username :Tulus || Password: 062)

- Proses pertama yang dapat dilakukan diapliksi digital shop yang saya buat ini, yaitu melakukan login input username dan password, setelah diinput langsung klik log in, jika username atau password salah maka akan muncul dialog username atau password anda salah!

2. Masuk ketampilan welcome
- LOGIN SUKSES

3. Masuk ke menu TabHost (Katalog)
- Dimenu katalog kita bisa lihat gambar, nama produk dan harga.

4. Menu TabHost (Pesan)
- Disini saya membuat 2 pilihan kondisi produk new dan second, menggunakan radiogroup & radiobutton
- Apabila diklik salah satunya maka akan muncul toast seperti contoh dibawah ini.

Lalu klik tombol proses, dan langsung terlihat total belanja dll.

Setelah itu klik tombol reset, dan tampilan akan muncul seperti dibawah ini.

5. Exit

- Ditampilan exit kita bisa masuk ke form login lagi dengan mengklik tombol back to form login, atau langsung close aplikasinya jika ingin keluar dari aplikasi digital shop.

Sekian hanya itu saja tutorial yang bisa saya berikan, project ini dibuat yang bertujuan untuk pengambilan nilai UTS mata kuliah mobile programming.
