Tutorial Membuat Aplikasi Name Card dengan Android Studio

Aplikasi Name Card

Halo sobat 48😁 kali ini saya akan membagikan sebuah artikel yang berjudul Tutorial Membuat Aplikasi Name Card dengan Android Studio. Disini saya akan membahas bagaimana cara untuk membuat aplikasi Name Card atau Kartu Nama menggunakan Database SQLite. Dengan aplikasi Name Card ini kalian bisa menyimpan kontak orang yang menurut kalian penting, mulai dari: Nama, Tanggal Lahir, Telepon dan Alamat seperti layaknya Aplikasi Biodata yang pernah saya buatkan tutorialnya.

Selain itu, disini saya menambahkan opsi untuk Update, View (Lihat Data) dan Hapus. Jika kalian ingin SOURCE CODE Aplikasi Name Card ini, silahkan download di Github saya DISINI. Tetapi jika kalian ingin tahu cara mengaplikasikannya, silahkan lanjut baca artikel ini sampai selesai😄

Oke langsung saja tanpa basa-basi lagi kita langsung ke langkah pertama :

1. Buat project baru di Android Studio dengan cara klik File ⇒ Project Baru. Ketika diminta untuk memilih Default Activity, pilih Empty Activity dan klik next. Untuk minSDK, disini saya set API 16 ya.

2. Buka build.gradle dan ubah menjadi seperti ini :

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support:design:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

3. Buka AndroidManifest.xml dan ubah menjadi seperti ini :

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.azhar.namecard">

    <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=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity android:name=".BuatKontak"
            android:label="@string/title_activity_buatbiodata">
        </activity>
        <activity android:name=".LihatKontak"
            android:label="@string/title_activity_lihatbiodata">
        </activity>
        <activity android:name=".UpdateKontak"
            android:label="@string/title_activity_updatebiodata">
        </activity>
    </application>

</manifest>

4. Ubah isi MainActivity.java dan activity_main.xml menjadi seperti ini :

package com.azhar.namecard;

import android.app.AlertDialog;
import android.content.DialogInterface;
import android.content.Intent;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.os.Bundle;
import android.support.design.widget.FloatingActionButton;
import android.support.v7.app.AppCompatActivity;
import android.view.Menu;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.ListView;

                startActivity(inte);
            }

        daftar = new String[cursor.getCount()];
        cursor.moveToFirst();
        for (int cc = 0; cc < cursor.getCount(); cc++) {
            cursor.moveToPosition(cc);
            daftar[cc] = cursor.getString(1).toString();
        }
        ListView01 = (ListView) findViewById(R.id.listView1);
        ListView01.setAdapter(new ArrayAdapter(this, android.R.layout.simple_list_item_1, daftar));

                                        Intent in = new Intent(getApplicationContext(), UpdateKontak.class);

5. Buat BuatKontak.java dan activity_buat_kontak.xml :

7. Buat LihatKontak.java dan activity_lihat_kontak.xml :

import android.os.Bundle;
import android.support.design.widget.FloatingActionButton;

import android.widget.TextView;

/**

public class LihatKontak extends AppCompatActivity {
    protected Cursor cursor;
    DataHelper dbHelper;
    FloatingActionButton ton2;
    TextView text1, text2, text3, text4, text5;

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

        dbHelper = new DataHelper(this);
        text1 = (TextView) findViewById(R.id.textView1);
        text2 = (TextView) findViewById(R.id.textView2);

        SQLiteDatabase db = dbHelper.getReadableDatabase();
        cursor = db.rawQuery("SELECT * FROM namecard WHERE nama = '" + getIntent().getStringExtra("nama") + "'", null);
        cursor.moveToFirst();
        if (cursor.getCount() > 0) {
            cursor.moveToPosition(0);
            text1.setText(cursor.getString(0).toString());
            text2.setText(cursor.getString(1).toString());
            text3.setText(cursor.getString(2).toString());
            text4.setText(cursor.getString(3).toString());
            text5.setText(cursor.getString(4).toString());
        }
        ton2 = (FloatingActionButton) findViewById(R.id.button1);
        ton2.setOnClickListener(new View.OnClickListener() {

8. Langkah yang terakhir buat Databasenya DataHelper.java dan isinya seperti ini :

package com.azhar.namecard;

import android.content.Context;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;
import android.util.Log;

/**
 * Created by Azhar Rivaldi on 09/04/2019.
 */

public class DataHelper extends SQLiteOpenHelper {
    private static final String DATABASE_NAME = "kontak.db";
    private static final int DATABASE_VERSION = 1;

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

    @Override
    public void onCreate(SQLiteDatabase db) {
        String sql = "create table namecard(no integer primary key, nama text null, tgl text null, tlp text null, alamat text null);";
        Log.d("Data", "onCreate: " + sql);
        db.execSQL(sql);
        sql = "INSERT INTO namecard (no, nama, tgl, tlp, alamat) VALUES ('1', 'Azhar Rivadi', '1996-07-09', '0217819078','Jakarta');";
        db.execSQL(sql);
    }

    @Override
    public void onUpgrade(SQLiteDatabase arg0, int arg1, int arg2) {
    }
}

Jika sudah selesai, silahkan kalian RUN dengan emulator bawaan Android Studio atau langsung melalui Device. Untuk hasil outpunya seperti ini:
