</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

package com.e.utsmobileprograming;

import androidx.appcompat.app.AppCompatActivity;

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.
