I can't understand what you mean by go to home page?

If u want to go HomeActivity/MainActivity, Just set a listener on the imageButton with an intent to start your home activity

Kotlin

class MainActivity : AppCompatActivity() {
    private lateinit var imageButton : ImageButton
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        imageButton = findViewById(R.id.iv_home)

        imageButton.setOnClickListener {
            val intent = Intent(this, HomeActivity::class.java)
            startActivity(intent)
            finish()
        }
    }
}

Java

public class MainActivity extends AppCompatActivity {
    private ImageButton imageButton;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        imageButton = findViewById(R.id.iv_home);
        imageButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent = new Intent(MainActivity.this, HomeActivity.class);
                startActivity(intent);
                finish();
            }
        });
    }
}
