Comment ajouter un tiroir de navigation sur l'application pré-construite?

Question

Je suis nouveau pour le développement Android. J'ai déjà construit mon application sans tiroir de navigation. Maintenant, je veux ajouter un tiroir de navigation qui sera identique pour toutes les activités de mon application. Aidez-moi sur cette question.

En supposant que vos activités d'origine étendent 'AppCompatActivity', effectuez l'activité de base comme suit et étendez toutes vos autres activités à 'BaseActivity'. La mise en page BaseActivity contentera DrawaerLayout et un framelayout. Inside BaseActivity ovveride setcontentview méthode et inflat votre disposition d'activité à l'intérieur framelayout.

BaseActivity.Java

public class BaseActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener { 


    private FrameLayout baseLayout; 
    public ActionBarDrawerToggle drawerToggle; 
    public Toolbar toolbar; 

    @Override 
    protected void onCreate(@Nullable Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     super.setContentView(R.layout.base_layout); 
     toolbar = (Toolbar) findViewById(R.id.toolbar); 
     setSupportActionBar(toolbar); 
     baseLayout = (FrameLayout) findViewById(R.id.base_view); 
     NavigationView navigationView = (NavigationView) findViewById(R.id.navigation_view); 
     DrawerLayout drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout); 
     navigationView.setNavigationItemSelectedListener(this); 
     drawerToggle = new ActionBarDrawerToggle(this, drawerLayout, toolbar, 0, 0); 
     drawerLayout.addDrawerListener(drawerToggle); 
    } 

    @Override 
    public void setContentView(View view) { 
     if (baseLayout != null) { 
      ViewGroup.LayoutParams params = new ViewGroup.LayoutParams(
        ViewGroup.LayoutParams.MATCH_PARENT, 
        ViewGroup.LayoutParams.MATCH_PARENT); 
      baseLayout.addView(view, params); 
     } 
    } 

    @Override 
    public void setContentView(View view, ViewGroup.LayoutParams params) { 
     if (baseLayout != null) { 
      baseLayout.addView(view, params); 
     } 
    } 

    @Override 
    public boolean onNavigationItemSelected(@NonNull MenuItem item) { 
     //TODO 
     return false; 
    } 
} 

base_layout.xml

Ajouter drawer.xml dans le dossier "menu" dans vos ressources.

<?xml version="1.0" encoding="utf-8"?> 
<menu xmlns:android="http://schemas.android.com/apk/res/android" 
    android:checkableBehavior="single"> 
    <item 
     android:id="@+id/nav_home" 
     android:icon="@drawable/icon_home" 
     android:title="Home" /> 


</menu>
