Les meilleures pratiques pour setOnClickListener dans le tiroir de navigation personnalisé

Question

J'utilise un tiroir de navigation personnalisé dans mon application. Pour les activités de commutation, j'utilise setOnClickListener pour chaque bouton. Mais je pense que cela pourrait consommer beaucoup de mémoire car le même code doit être chargé dans chaque activité à chaque fois. Donc, y a-t-il un moyen efficace de gérer sur l'écouteur de clic pour le menu comme cas de commutateur?

Mon code pour les clics nav-point.

Button oneButton = (Button) findViewById(R.id.nav_one); 
    Button twoButton = (Button) findViewById(R.id.nav_two); 
    Button threeButton = (Button) findViewById(R.id.nav_three); 
    Button fourButton = (Button) findViewById(R.id.nav_four); 
    Button fiveeButton = (Button) findViewById(R.id.nav_five); 

     oneButton.setOnClickListener(new View.OnClickListener() { 
@Override 
public void onClick(View view) { 

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

     Intent firstIntent = new Intent(getApplicationContext(), MainActivity.class); 
     startActivity(firstIntent); 
     } 
     }); 

     twoButton.setOnClickListener(new View.OnClickListener() { 
@Override 
public void onClick(View view) { 

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

     Intent secondIntent = new Intent(getApplicationContext(), SecondActivity.class); 
     startActivity(secondIntent); 

     } 
     }); 

     threeButton.setOnClickListener(new View.OnClickListener() { 
@Override 
public void onClick(View view) { 

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

     Intent threeButton = new Intent(getApplicationContext(), ThirdActivity.class); 
     startActivity(thirdIntent); 

     } 
     }); 

     threeButton.setOnClickListener(new View.OnClickListener() { 
@Override 
public void onClick(View view) { 

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

     Intent fourButton = new Intent(getApplicationContext(), FouthActivity.class); 
     startActivity(fourthIntent); 

     } 
     }); 

     fourButton.setOnClickListener(new View.OnClickListener() { 
@Override 
public void onClick(View view) { 


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

     Intent fiveButton = new Intent(getApplicationContext(), FifthouthActivity.class); 
     startActivity(fifthIntent); 
     } 
     });

Utilisez cette méthode, il peut vous aider

Ne pas oublier d'ajouter cette

class YourClass ... implements View.OnClickListener 

    onCreate { 
     Button oneButton = (Button) findViewById(R.id.nav_one); 
     Button twoButton = (Button) findViewById(R.id.nav_two); 
     Button threeButton = (Button) findViewById(R.id.nav_three); 
     Button fourButton = (Button) findViewById(R.id.nav_four); 
     Button fiveeButton = (Button) findViewById(R.id.nav_five); 

     DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout); 

     oneButton.setOnClickListener(this); 
     twoButton .setOnClickListener(this); 
     threeButton .setOnClickListener(this); 
     fourButton .setOnClickListener(this); 
     fiveeButton .setOnClickListener(this); 
    }//onCreate method ends here 

    @Override 
    public void onClick(View view) { 

     switch (view.getId()) 
     { 

      case R.id.nav_one: 
       drawer.closeDrawer(GravityCompat.START); 

       Intent firstIntent = new Intent(getApplicationContext(), MainActivity.class); 
       startActivity(firstIntent); 
       break; 
      case R.id.nav_two: 
       //same way other buttons also 

     } 
    }
