Tutorial Membuat Aplikasi Barcode Generator dengan Android Studio

Barcode Generator
Barcode Generator
Halo sobat 48😁 kali ini admin akan membagikan sebuah tutorial dengan tema Tutorial Membuat Aplikasi Barcode Generator dengan Android Studio. Untuk WhatsApp Mod saya skip dulu ya gan😂. Oh ya, aplikasi Barcode Generator ini berfungsi bisa untuk Scan Barcode, membuat QR code dan membuat Barcode. Kalian cukup memilih Tab yang ada untuk membuka menu-menu tersebut.

VIDEO PREVIEW:

Gimana setelah melihat vide preview diatas? Untuk SOURCE CODE kalian bisa download DISINI. Apa kalian tertarik untuk membuatnya sendiri? Kalau ya, berikut admin akan jelaskan langkah-langkah untuk membuat Aplikasi Barcode Generator:

1. Buat Project Baru
  • Pastikan kalian sudah instal Android Studio
  • Buat Project baru, disini saya memberi nama Barcode Generator
2. Tambahkan Gradle


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'
implementation 'me.dm7.barcodescanner:zbar:1.9.8'
implementation 'me.dm7.barcodescanner:zxing:1.9.8'

3. Buat activity_main.xml


<?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"

android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">

<FrameLayout
android:id="@+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />

<android.support.design.widget.BottomNavigationView
android:id="@+id/bottomNavigationView"
android:layout_width="match_parent"

app:elevation="3dp" />

</LinearLayout>

</RelativeLayout>

</ScrollView>

</RelativeLayout>

6. Buat fragment_generate_qrcode.xml


<?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"
android:layout_width="match_parent"

7. Buat fragment_scan.xml


<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">

<FrameLayout

8. Buat folder menu, dan isikan didalamnya menu_bottom.xml


<?xml version="1.0" encoding="utf-8"?>

android:icon="@drawable/ic_generate"
android:title="Barcode" />

<item
android:id="@+id/navigation_generate_qrcode"
android:icon="@drawable/ic_generate"
android:title="QR" />

</menu>

9. Buat MainActivity.java


package com.azhar.barcodegenerator;

import android.Manifest;
import android.content.Context;
import android.content.pm.PackageManager;
import android.os.Bundle;
import android.support.annotation.NonNull;
import android.support.design.widget.BottomNavigationView;
import android.support.v4.app.ActivityCompat;
import android.support.v4.app.FragmentTransaction;
import android.support.v7.app.AppCompatActivity;
import android.view.MenuItem;

import com.azhar.barcodegenerator.fragments.GenerateBarcodeFragment;
import com.azhar.barcodegenerator.fragments.GenerateQRcodeFragment;
import com.azhar.barcodegenerator.fragments.ScanFragment;

public class MainActivity extends AppCompatActivity {

private BottomNavigationView mBottomNavigationView;

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

mBottomNavigationView = findViewById(R.id.bottomNavigationView);
mBottomNavigationView.setOnNavigationItemSelectedListener(mOnNavigationItemSelectedListener);

FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
transaction.replace(R.id.content_frame, new ScanFragment());
transaction.commit();
}

public static boolean hasPermissions(Context context, String... permissions) {
if (context != null && permissions != null) {
for (String permission : permissions) {
if (ActivityCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED) {
return false;
}
}
}
return true;
}

private void checkPermission() {
int PERMISSION_ALL = 1;
String[] PERMISSIONS = {
Manifest.permission.READ_EXTERNAL_STORAGE,
Manifest.permission.WRITE_EXTERNAL_STORAGE,
Manifest.permission.CAMERA
};

if (!hasPermissions(this, PERMISSIONS)) {
ActivityCompat.requestPermissions(this, PERMISSIONS, PERMISSION_ALL);
}
}

private BottomNavigationView.OnNavigationItemSelectedListener mOnNavigationItemSelectedListener
= new BottomNavigationView.OnNavigationItemSelectedListener() {

@Override
public boolean onNavigationItemSelected(@NonNull MenuItem item) {
switch (item.getItemId()) {
case R.id.navigation_scan:
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
transaction.replace(R.id.content_frame, new ScanFragment());
transaction.commit();
return true;
case R.id.navigation_generate_barcode:
FragmentTransaction transaction2 = getSupportFragmentManager().beginTransaction();
transaction2.replace(R.id.content_frame, new GenerateBarcodeFragment());
transaction2.commit();
return true;
case R.id.navigation_generate_qrcode:
FragmentTransaction transaction3 = getSupportFragmentManager().beginTransaction();
transaction3.replace(R.id.content_frame, new GenerateQRcodeFragment());
transaction3.commit();
return true;
}
return false;
}
};
}

10. Buat folder fragment lalu buat CustomDialogFragment.java, GenerateBarcodeFragment.java, GenerateQRcodeFragment.java, MessageDialogFragment.java dan ScanFragment.java


package com.azhar.barcodegenerator.fragments;

import android.support.annotation.Nullable;

import com.azhar.barcodegenerator.R;

public class CustomDialogFragment extends DialogFragment {

private TextView mActionOk, mActionCancel;
private EditText editTextNewContent;

@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_custom_dialog, container, false);

mActionCancel = view.findViewById(R.id.action_cancel);
mActionOk = view.findViewById(R.id.action_ok);
editTextNewContent = view.findViewById(R.id.editTextNewContent);

if (getArguments() != null) {
if (getArguments().containsKey("content")) {
editTextNewContent.setText(getArguments().getString("content"));
}
}

mActionCancel.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
getDialog().dismiss();
}
});

mActionOk.setOnClickListener(new View.OnClickListener() {
@Override

getDialog().dismiss();

});

return view;
}
}

11. Ubah Android Manifest.xml
