Tugas UAS

Sama seperti postingan sebelumnya, kita siapkan terlebih dahulu tiga file pdf yang nantinya akan di taruh dalam Direktori Assets. File pdf nya jangan yang berat-berat gan, biar aplikasinya gak makan banyak ruang penyimpanan 😀 .

Selanjutnya buka Android Studio – Buat Project baru – Sesuaikan nama Package dengan yang kalian inginkan.

Ingat dengan tiga file pdf yang sudah kita siapkan tadi? Nah, sekarang akan kita masukkan kedalam project kita ini 😀
Masuk ke dalam App > main dan buat folder bernama assets. Lalu tempatkan file pdf kita tadi ke dalam folder assets tersebut. Lalu Rename file pdf kita itu dengan nama sample_1.pdf, sample_2.pdf, dan sample_3.pdf .

Selanjutnya, buka Gradle Scripts >build:gradle (Module:app) untuk di implementasi kan dengan project kita.

masukkan code :

implementation 'com.github.barteksc:android-pdf-viewer:2.8.2'

letakkan code di paling bawah gradle

Sinkronisasikan gradle dengan menekan Sync Now.

Lalu kita menuju app > java > [ nama.package.kalian ] dan buat dua fragment :

ListFragment.java
Pdf_sampleFragment.java

Lalu buat satu activity :

Main2Activity.java

Masukkan code pada :

ListFragment.java

package com.example.app_login_pdf;

import android.os.Bundle;

import androidx.fragment.app.Fragment;

import androidx.fragment.app.FragmentTransaction;

import android.view.LayoutInflater;

import android.view.View;

import android.view.ViewGroup;

import android.widget.ArrayAdapter;

import android.widget.ListView;

/**

public class ListFragment extends Fragment {

public ListFragment() {

// Required empty public constructor

}

@Override

public View onCreateView(LayoutInflater inflater, ViewGroup container,

Bundle savedInstanceState) {

// Inflate the layout for this fragment

View rootView = inflater.inflate(R.layout.fragment_list, container, false);

listView =(ListView) rootView.findViewById(R.id.list);

String[] values = new String[] {

"Sampul Cover",

"Kata Pengantar",

"Isi",

"Sampul Cover Ke 2",

"Kata Pengantar Ke 2",

"Isi Ke 2",

"Sampul Cover Ke 3",

"Kata Pengantar Ke 3",

"Isi Ke 3",

"Fadil Muhamad",

"161021450535",

};

ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity(), android.R.layout.simple_list_item_1, android.R.id.text1, values);

listView.setAdapter(adapter);

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {

@Override

}

return super.onOptionsItemSelected(item);

}

/**

* Listener for response to user permission request

* @param requestCode Check that permission request code matches

* @param permissions Permissions that requested

* @param grantResults Whether permissions granted

}

Lalu kita lanjutkan pada MainActivity.java . Activity ini untuk form login yang akan kita buat.

Buka MainActivity.java lalu masukkan code berikut :

MainActivity.java

package com.example.app_login_pdf;

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 MainActivity extends AppCompatActivity {

private Button btnlng;

private EditText inuser, inpass;

//public String username, password;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

inuser = (EditText) findViewById(R.id.inuser);

inpass = (EditText) findViewById(R.id.inpass);

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

btnlng.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View view) {

if (inuser.getText().toString().equals("admin") && inpass.getText().toString().equals("admin")){

Toast.makeText(getApplicationContext(),"Anda Login Sebagai : "+ inuser.getText().toString() + " dan Password : "+inpass.getText().toString(),Toast.LENGTH_SHORT).show();

Intent i = new Intent(MainActivity.this, Main2Activity.class);

i.putExtra("username",inuser.getText().toString());

i.putExtra("password",inpass.getText().toString());

startActivity(i);

}

else {

Toast.makeText(getApplicationContext(),"Username dan Pssword tidak sesuai Anda gagal Login",Toast.LENGTH_SHORT).show();

}

});

}

Saya membuat default username & passwordnya itu admin dan admin.

Buka Main2Activity.java lalu masukkan code berikut :

Main2Activity.java

package com.example.app_login_pdf;

import androidx.appcompat.app.AppCompatActivity;

import androidx.fragment.app.FragmentTransaction;

import androidx.fragment.app.FragmentTransitionImpl;

import android.content.Intent;

import android.os.Bundle;

import android.os.Handler;

import android.widget.Toast;

public class Main2Activity extends AppCompatActivity {

private static final int TIME_DELAY = 2000;

private static long back_pressed;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main2);

ListFragment listFragment = new ListFragment();

FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();

fragmentTransaction.replace(R.id.content, listFragment);

fragmentTransaction.commit();

}

boolean doubleBackToExitPressedOnce = false;

@Override

public void onBackPressed() {

//Checking for fragment count on backstack

if (getSupportFragmentManager().getBackStackEntryCount() > 0) {

getSupportFragmentManager().popBackStack();

} else if (!doubleBackToExitPressedOnce) {

this.doubleBackToExitPressedOnce = true;

Toast.makeText(this,"Tekan sekali lagi untuk keluar!", Toast.LENGTH_SHORT).show();

new Handler().postDelayed(new Runnable() {

@Override

public void run() {

doubleBackToExitPressedOnce = false;

}

}, 2000);

} else {

super.onBackPressed();

return;

}

Nah, sekarang kita tinggal menyesuaikan layoutnya saja. masukkan code berikut :
