2. 다른 화면 구성

activity main 과 동일한 코드로 다른 화면 구성

3. MainActivity

import androidx.annotation.NonNull;
import androidx.appcompat.app.AppCompatActivity;

import android.content.Intent;
import android.os.Bundle;
import android.view.MenuItem;

import com.google.android.material.bottomnavigation.BottomNavigationView;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        //바텀네비 설정
        BottomNavigationView bottomNavigationView = findViewById(R.id.bottom_navigation);
        bottomNavigationView.setSelectedItemId(R.id.home);
        bottomNavigationView.setOnNavigationItemReselectedListener(new BottomNavigationView.OnNavigationItemReselectedListener() {
            @Override
            public void onNavigationItemReselected(@NonNull MenuItem menuItem) {
                switch (menuItem.getItemId()){
                    case R.id.dashboard:
                        startActivity(new Intent(getApplicationContext(),DashBoard.class));
                        overridePendingTransition(0,0);
                        return;

                    case R.id.home:
                        return;

                    case R.id.about:
                        startActivity(new Intent(getApplicationContext(),About.class));
                        overridePendingTransition(0,0);
                        return;

                }


            }
        });
    }
