如何在導航紙盒上爲不同的選定項目設置不同的背景顏色？

我想爲Navigation Drawer上的不同選定項目設置不同的背景顏色。如何在導航紙盒上爲不同的選定項目設置不同的背景顏色？

贊，對於nav_camara它是紅色的，因爲nav_gallery是藍色等等。

我的MainActivity代碼

public class MainActivity extends AppCompatActivity 
    implements NavigationView.OnNavigationItemSelectedListener { 

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

    FragmentTransaction ft = getSupportFragmentManager().beginTransaction(); 
    ft.replace(R.id.main_fragment, new Main()); 
    ft.commit(); 


    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); 
    setSupportActionBar(toolbar); 



    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout); 
    ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
      this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close); 
    drawer.setDrawerListener(toggle); 
    toggle.syncState(); 

    NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view); 
    navigationView.setNavigationItemSelectedListener(this); 
} 

@Override 
public void onBackPressed() { 
    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout); 
    if (drawer.isDrawerOpen(GravityCompat.START)) { 
     drawer.closeDrawer(GravityCompat.START); 
    } else { 
     super.onBackPressed(); 
    } 
} 


@SuppressWarnings("StatementWithEmptyBody") 
@Override 
public boolean onNavigationItemSelected(MenuItem item) { 
    // Handle navigation view item clicks here. 
    int id = item.getItemId(); 

    if (id == R.id.nav_camara) { 
     FragmentTransaction ft = getSupportFragmentManager().beginTransaction(); 
     ft.replace(R.id.main_fragment, new Daily_packs_bl()); 
     ft.commit(); 
     getSupportActionBar().setTitle("Daily"); 
    } else if (id == R.id.nav_gallery) { 
     FragmentTransaction ft = getSupportFragmentManager().beginTransaction(); 
     ft.replace(R.id.main_fragment, new HI()); 
     ft.commit(); 
     getSupportActionBar().setTitle("HI"); 

    } else if (id == R.id.nav_slideshow) { 
     FragmentTransaction ft = getSupportFragmentManager().beginTransaction(); 
     ft.replace(R.id.main_fragment, new Two()); 
     ft.commit(); 
     getSupportActionBar().setTitle("Two"); 


    } 

    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout); 
    drawer.closeDrawer(GravityCompat.START); 
    return true; 
}

}
