1. Create the layout file activity_main.xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:padding="16dp">

<TableLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:stretchColumns="1">

<TableRow>
<TextView
android:text="Username"
android:padding="8dp"
android:textSize="18sp" />

<EditText
android:id="@+id/editTextUsername"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="8dp"
android:hint="Enter your username" />
</TableRow>

<TableRow>
<TextView
android:text="Password"
android:padding="8dp"
android:textSize="18sp" />

<EditText
android:id="@+id/editTextPassword"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="8dp"
android:inputType="textPassword"
android:hint="Enter your password" />
</TableRow>

<TableRow>
<Button
android:id="@+id/btnLogin"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Login" />
</TableRow>
</TableLayout>
</LinearLayout>

2. Create Second Activity Layout (activity_second.xml):

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:gravity="center">

<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Welcome to the Second Activity!"
android:textSize="20sp"
android:textStyle="bold"
android:padding="16dp"/>

</LinearLayout>

3. Create MainActivity Class (MainActivity.java):

import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TableRow;
import android.widget.Toast;

import androidx.appcompat.app.AppCompatActivity;

public class MainActivity extends AppCompatActivity {

private EditText editTextUsername, editTextPassword;
private Button btnLogin;

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

editTextUsername = findViewById(R.id.editTextUsername);
editTextPassword = findViewById(R.id.editTextPassword);
btnLogin = findViewById(R.id.btnLogin);

btnLogin.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
performLogin();
}
});
}

private void performLogin() {
String username = editTextUsername.getText().toString().trim();
String password = editTextPassword.getText().toString().trim();

// Check hardcoded login credentials (You can replace this with your own logic)
if (username.equals("user") && password.equals("password")) {

// Successful login, show a toast
Toast.makeText(this, "Login Successful!", Toast.LENGTH_SHORT).show();

// Start the second activity
Intent intent = new Intent(MainActivity.this, SecondActivity.class);
startActivity(intent);
} else {
// Invalid login, show a toast
Toast.makeText(this, "Invalid username or password", Toast.LENGTH_SHORT).show();
}
}
}

4. Create SecondActivity Class (SecondActivity.java):

import android.os.Bundle;
import android.widget.TextView;

import androidx.appcompat.app.AppCompatActivity;
public class SecondActivity extends AppCompatActivity {

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

TextView textViewWelcome=findViewById(R.id.textViewWelcome);
}
}
