      android:layout_width="match_parent"

* Create a new file called `admin_panel.java` in the `app > src > main > java > com.example.quizze` directory and add the following lines of code:
```java
public class AdminPanel extends AppCompatActivity {
    private EditText usernameEditText;
    private EditText passwordEditText;

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

        usernameEditText = findViewById(R.id.username);
        passwordEditText = findViewById(R.id.password);
        loginButton = findViewById(R.id.login);

        loginButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                String username = usernameEditText.getText().toString();
                String password = passwordEditText.getText().toString();

                // Check if the username and password are valid
                if (/* username and password are valid */) {
                    // Start the quiz activity
                    startActivity(new Intent(AdminPanel.this, QuizActivity.class));
                } else {
                    // Show an error message
                    Toast.makeText(AdminPanel.this, "Invalid username or password", Toast.LENGTH_SHORT).show();
                }
            }
